A urobilinogen result of 0.2 mg/dL on a urine test is considered normal, since typical reference ranges fall between 0.1 and 1.0 mg/dL. This value suggests your liver, bile ducts, and red blood cell breakdown are functioning as expected, and it is generally not a cause for concern on its own. However, urobilinogen is interpreted alongside other urinalysis markers like bilirubin, blood, protein, and urine color, and factors such as dehydration, recent antibiotics, or vitamin C intake can shift results. There are several important details to consider before assuming your result is meaningless, especially if you have symptoms like fatigue, dark urine, pale stools, abdominal pain, or yellowing of the skin or eyes. See below to understand what a 0.2 reading does and does not rule out. If you have symptoms that prompted this test, or your result came back alongside other abnormal values, a lab number alone will not tell you the full story. Taking a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> takes only a few minutes, uses your specific symptoms and history, and helps you understand which conditions are worth discussing and how urgently you should act. It is a practical first step toward knowing whether you can monitor at home or should book an appointment soon. Last reviewed for medical accuracy: 10/09/2026

Absolute neutrophil count (ANC) measures the actual number of neutrophils, the white blood cells that form your body's first defense against bacterial and fungal infection, typically reported as cells per microliter with a normal adult range of roughly 1,500 to 8,000. A high ANC (neutrophilia) often points to infection, inflammation, physical or emotional stress, smoking, corticosteroid use, or less commonly a bone marrow disorder, while a low ANC (neutropenia) can follow chemotherapy, viral illness, certain medications, autoimmune conditions, or vitamin B12 and folate deficiency, and raises infection risk as levels drop below 1,000 and especially below 500. Because the same number can mean very different things depending on your symptoms, medications, recent illnesses, and the rest of your CBC, there are several important factors to consider before drawing conclusions, which are explained below. Rather than guessing what your result signals, you can take a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> to see how your ANC fits with what you are actually experiencing. It takes only a few minutes, is private, and gives you a clearer, better-organized picture to bring to your doctor so your next appointment leads to answers instead of more questions.

A positive or abnormal leukocyte esterase result means white blood cells are present in your urine, which usually points to inflammation or infection somewhere in the urinary tract, most often a bladder infection (UTI). It can also be triggered by kidney infection, kidney stones, sexually transmitted infections, vaginal inflammation or contamination, strenuous exercise, pregnancy, or a catheter, and results are typically read alongside nitrites, blood, and a urine culture before anything is confirmed. A false positive or a false negative is possible, so the strength of the reading, your symptoms, and your medical history all change what the result actually means. There are several important factors and follow-up steps to consider, including when this finding needs urgent care, so see below to understand more. Because an abnormal leukocyte esterase reading can mean anything from a simple contaminated sample to an infection moving toward your kidneys, the fastest way to make sense of it is to look at it next to your actual symptoms. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> walks you through questions about burning, urgency, flank or back pain, fever, and other clues, then helps you understand likely explanations and how soon you should be seen.

AST (aspartate aminotransferase) is an enzyme found mainly in the liver, but also in the heart, muscles, kidneys, brain, and red blood cells, and blood levels rise when those cells are damaged or inflamed. Common causes of elevated AST include fatty liver disease, alcohol use, viral hepatitis, certain medications and supplements, strenuous exercise, muscle injury, hemolysis, and heart conditions. Most labs consider roughly 8 to 33 U/L normal, though reference ranges vary, and the AST to ALT ratio often helps clinicians distinguish liver causes from muscle or alcohol-related ones. Mild elevations are frequently temporary and harmless, while persistent or very high results warrant further testing. Several important factors affect how your result should be interpreted, so see below to understand more. Because AST alone rarely tells the full story, it helps to look at your result alongside your symptoms, medications, and health history before assuming the worst. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are experiencing, see which conditions may explain an elevated AST, and understand which follow-up tests or specialists may be worth discussing with your doctor. It takes just a few minutes, requires no sign-up, and gives you clearer questions to bring to your next appointment instead of guessing or worrying. Last reviewed for medical accuracy: 10/09/2025

Lethargy means more than ordinary tiredness: it is a state of sluggishness, low energy, mental fog, and reduced alertness that rest does not fully relieve, and it can stem from dehydration, poor sleep, infection, anemia, thyroid problems, depression, medication side effects, or serious conditions affecting the heart, liver, kidneys, or brain. Several warning signs mean you should see a doctor promptly, including lethargy with fever, confusion, slurred speech, chest pain, shortness of breath, fainting, unexplained weight loss, or symptoms lasting more than two weeks, and there are important age-specific red flags for infants and older adults you should consider below. Because lethargy overlaps so many causes, from easily fixable habits to urgent medical emergencies, guessing can delay care that matters. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> lets you describe what you are feeling in a few minutes and see which conditions best match your pattern.

Bubbles in urine in men are often harmless, caused by a fast urine stream, a full bladder, toilet cleaning products, or mild dehydration, but persistent foam can signal protein in the urine (proteinuria) linked to kidney disease, diabetes, or high blood pressure, and less commonly retrograde ejaculation, a urinary tract infection, or a rare bladder fistula. Key warning signs include foam that lingers after flushing, swelling in the feet, ankles, face, or hands, cloudy or dark urine, burning during urination, and fatigue. There are several important distinctions between normal bubbles and true foamy urine, including how long symptoms last and which conditions require urgent testing, so see below to understand more before deciding whether to wait or seek care.

A low sodium result does not always signal disease, since drinking too much water, intense endurance exercise, very low-salt diets, or heavy fluid loss from sweating, vomiting, or diarrhea can temporarily dilute blood sodium. Lab-related causes also matter, including pseudohyponatremia from high blood fats or proteins, blood drawn near an IV line, or sample handling issues that skew the reading. Common medications such as diuretics, antidepressants, and NSAIDs can lower sodium even in otherwise healthy people. There are several important distinctions between a harmless fluctuation and a result that needs follow-up testing, and they are explained in detail below.

Low potassium on a blood test, called hypokalemia, most often results from potassium loss through the digestive tract or kidneys, including vomiting, diarrhea, laxative overuse, and diuretic medications. Other common causes include excessive sweating, chronic kidney disease, hormonal disorders such as hyperaldosteronism or Cushing syndrome, low magnesium levels, and shifts of potassium into cells triggered by insulin, certain asthma inhalers, or alkalosis. Rarely, inadequate dietary intake, alcohol use disorder, eating disorders, or inherited conditions like Gitelman or Bartter syndrome are responsible, and some results are falsely low due to sample handling. Symptoms range from none at all to muscle weakness, cramping, constipation, fatigue, and irregular heartbeats that can become dangerous. There are several factors that determine which cause applies to you, including how low the level is and what medications you take, so see below for the important details to consider. Still unsure why your potassium came back low or what to do next? A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you connect your lab result with the symptoms you are actually experiencing, flag whether your medications or other conditions could be contributing, and clarify whether this calls for urgent care or a routine follow-up conversation with your doctor.

A low red blood cell count, often reported as anemia on a complete blood count, can stem from iron, vitamin B12, or folate deficiency, blood loss from heavy periods or gastrointestinal bleeding, chronic kidney disease, bone marrow disorders, inflammatory conditions, certain medications, pregnancy, or inherited conditions like thalassemia and sickle cell disease. Some causes are mild and easily corrected, while others signal a condition that needs prompt evaluation, so the specific pattern of your other lab values matters. There are several important factors to consider, including your symptoms, medical history, and related results such as hemoglobin, hematocrit, MCV, and ferritin, all explained in the complete answer below. Because the same lab finding can point to very different underlying problems, guessing can delay care you may need or cause worry you do not.

Glucose in your urine, called glycosuria, means sugar has spilled past your kidneys into your urine, most often because blood sugar is running high from diabetes or prediabetes. Other causes include pregnancy, kidney conditions such as renal glycosuria, certain medications like SGLT2 inhibitors, and stress or illness that temporarily raises blood sugar. A single positive result does not confirm diabetes, so doctors typically follow up with fasting glucose, A1C, or repeat urine testing. Warning signs that deserve prompt attention include excessive thirst, frequent urination, unexplained weight loss, blurred vision, and fatigue. There are several important factors to consider, including how your other test values and symptoms fit together, so review the complete details below before drawing conclusions. Because glucose in urine can point to anything from a harmless kidney quirk to undiagnosed diabetes, the smartest next step is clarifying which explanation matches your situation.

Hemoglobin is the iron-rich protein in your red blood cells that carries oxygen from your lungs to your tissues and returns carbon dioxide for exhalation, and your result reports how much of it is in your blood, typically in grams per deciliter. Low hemoglobin can point to anemia from iron, B12, or folate deficiency, blood loss, pregnancy, kidney disease, or chronic inflammation, while high hemoglobin may reflect dehydration, smoking, high altitude, lung or heart conditions, or a bone marrow disorder. Normal ranges differ by age, sex, pregnancy status, and altitude, and a single number out of range does not always mean disease, so there are several important factors to consider before drawing conclusions, explained in detail below. Because the same hemoglobin value can mean very different things depending on your symptoms, history, and other labs, the fastest way to make sense of yours is a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> that asks about fatigue, shortness of breath, dizziness, and other clues in minutes.

Immature granulocytes (IG) are young, not-yet-fully-developed white blood cells that are normally confined to the bone marrow, so finding more than a trace of them in circulating blood usually signals that your marrow is releasing defenders early, most often because of acute bacterial infection, sepsis, inflammation, tissue injury, surgery, steroid use, or pregnancy, though rarely it can point to a bone marrow or blood disorder such as leukemia or a myeloproliferative condition. A typical reference range is roughly 0 to 0.5 percent of white blood cells (about 0 to 0.03 x 10⁹/L), and a mildly elevated result in an otherwise healthy person is often temporary and not alarming. What matters most is the pattern, meaning whether your IG count is rising, how high it is, and what your neutrophils, total white count, and symptoms show alongside it. There are several important factors that change how this result should be interpreted, including timing, medications, and accompanying labs, so see below to understand more before drawing conclusions. Because an elevated immature granulocyte count can mean anything from a passing infection to something that needs prompt treatment, the smartest next step is to put your result in context with your actual symptoms, and a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you do exactly that in just a few minutes, giving you clearer language and better questions for your doctor instead of hours of uncertainty.

Elevated ALT and AST together usually signal that liver cells are injured or inflamed, with common causes including fatty liver disease, alcohol use, viral hepatitis, certain medications or supplements, and autoimmune or genetic liver conditions. The AST/ALT ratio matters: a ratio near or above 2:1 often points toward alcohol-related liver damage, while ALT higher than AST is more typical of fatty liver or viral hepatitis. Not every cause is the liver, since strenuous exercise, muscle injury, thyroid disease, and celiac disease can also raise both enzymes, and mildly high results are sometimes harmless or temporary. How high the numbers are, whether they are rising, and whether you have symptoms like jaundice, dark urine, abdominal pain, or swelling all change how urgent the situation is. There are several important factors to consider, including when values become dangerous and what testing typically comes next, so see below for the complete answer. Because abnormal ALT and AST results can mean anything from a minor, reversible issue to serious liver disease, the fastest way to make sense of your own numbers is to look at them alongside your symptoms, medications, and health history. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> takes just a few minutes, asks the same kinds of questions a clinician would, and helps you see which causes best fit your situation. It can also tell you whether this warrants a routine follow-up or more prompt medical attention, so you walk into your next appointment with clearer questions and less guesswork.

Ketones in your urine mean your body is burning fat instead of glucose for energy, which can happen with fasting, low-carb or ketogenic diets, prolonged vomiting, intense exercise, pregnancy, or illness. Small amounts are often harmless, but moderate to large levels may signal uncontrolled diabetes or diabetic ketoacidosis, a medical emergency that needs urgent care, especially alongside thirst, frequent urination, fruity breath, nausea, confusion, or rapid breathing. Because the meaning of a positive result depends on your ketone level, blood sugar, symptoms, and medical history, there are several important factors to consider before drawing conclusions.

Lethargy is a state of abnormally low energy and reduced alertness in which thinking feels slowed, movement feels heavy, and even simple tasks demand unusual effort. Unlike ordinary tiredness, which improves with rest, sleep, or a lighter schedule, lethargy tends to persist, worsen, or appear without any clear reason such as a late night or hard workout. It can signal underlying issues like anemia, thyroid disease, infection, dehydration, depression, medication side effects, or problems with blood sugar, and sudden lethargy paired with confusion, fever, or trouble breathing may be urgent. There are several important distinctions and warning signs to consider, so see below for the complete answer before deciding your next step. Because lethargy and everyday fatigue can look similar but mean very different things, it helps to sort through your specific symptoms rather than guess.

Lipase is a digestive enzyme made mainly by the pancreas, and a blood lipase test measures how much of it is circulating in your bloodstream, which helps doctors assess pancreatic health. A high lipase level, often three or more times the upper limit of normal, most commonly points to acute pancreatitis, but it can also be raised by gallstones, blocked pancreatic ducts, chronic pancreatitis, kidney disease, certain medications, bowel obstruction, or celiac disease. Mildly elevated results do not always mean pancreatic damage, and the number must be read alongside your symptoms, amylase levels, and imaging, so there are several important factors to consider before drawing conclusions, explained in detail below.

Low ferritin with normal hemoglobin signals that your body's iron stores are depleted even though red blood cell production is still holding steady, a stage often called iron deficiency without anemia. This can still cause real symptoms, including fatigue, hair thinning, brain fog, cold intolerance, restless legs, exercise intolerance, and shortness of breath, often months or years before hemoglobin falls. Common drivers include heavy menstrual periods, pregnancy, gastrointestinal blood loss, celiac disease or other absorption problems, low dietary iron, and frequent endurance training, and inflammation can falsely raise ferritin and mask the deficiency, so there are several important factors to consider before assuming the result is harmless; see below for the complete answer, including the ferritin thresholds that matter and when further testing is warranted.

Low MCH (mean corpuscular hemoglobin) and low MCHC (mean corpuscular hemoglobin concentration) mean your red blood cells carry less hemoglobin than expected, a pattern called hypochromic anemia that most often points to iron deficiency, chronic blood loss, or an inherited condition such as thalassemia. Less common causes include lead exposure, chronic inflammatory disease, vitamin B6 deficiency, and copper deficiency, and mildly low values can also appear in otherwise healthy people. Symptoms may include fatigue, pale skin, shortness of breath, headaches, cold hands and feet, or no symptoms at all, and your MCV, RDW, ferritin, and hemoglobin results all change how these numbers should be interpreted. There are several important factors to consider, including when low MCH and MCHC signal something that needs prompt evaluation; see below to understand more. If you are trying to make sense of your lab report and whether your symptoms fit the picture, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are experiencing, see which conditions commonly explain low MCH and MCHC, and know whether to request iron studies or book a visit now rather than wait.

A high MCV (mean corpuscular volume) means your red blood cells are larger than average, a condition called macrocytosis, which most often points to vitamin B12 or folate deficiency, heavy alcohol use, thyroid or liver problems, certain medications, or bone marrow disorders. Symptoms can include fatigue, weakness, pale skin, shortness of breath, tingling in the hands or feet, and trouble concentrating, though many people feel fine at first. A mildly elevated result is not always serious, but the cause matters, and it is usually interpreted alongside hemoglobin, hematocrit, MCH, and RDW rather than on its own. There are several important factors to consider, including when a high MCV needs follow-up testing and when it can be safely monitored, so see below to understand more.

Monocytes are a type of white blood cell made in the bone marrow that circulate in the blood, engulf germs and debris, and mature into macrophages and dendritic cells that help direct the immune response. A high monocyte count, called monocytosis, generally means more than about 800 to 1,000 monocytes per microliter, or over roughly 10 percent of total white blood cells on a complete blood count. Common causes include recovery from infection, chronic bacterial or viral infections such as tuberculosis or mononucleosis, autoimmune and inflammatory conditions like lupus or inflammatory bowel disease, and less often blood disorders such as leukemia. Because results are interpreted alongside your other blood counts, symptoms, medications, and medical history, there are several important factors to consider, and the details below explain what truly elevated levels may signal and when testing should be repeated. A lab number on its own rarely tells the whole story, and the difference between a harmless post-infection rebound and something that needs prompt attention often comes down to the symptoms you are experiencing right now, such as fever, night sweats, unexplained weight loss, fatigue, swollen lymph nodes, or easy bruising.

Nitrite in your urine is not normally present, and a positive result most often means bacteria such as E. coli are converting nitrate into nitrite, which points toward a urinary tract infection involving the bladder, urethra, or kidneys. Common accompanying signs include burning during urination, urgency, frequent urination, cloudy or strong smelling urine, and pelvic pressure, while fever, chills, nausea, or flank pain can suggest the infection has reached the kidneys and needs prompt care. A negative nitrite result does not fully rule out an infection, because some bacteria do not produce nitrite, and diet, vitamin C, dilute urine, recent antibiotics, and how long the sample sat before testing can all skew results, so there are several important factors to consider before drawing conclusions. See below to understand more about what your full urinalysis findings, including leukocyte esterase, blood, and protein, may mean together.

RDW, or red cell distribution width, measures how much your red blood cells vary in size, and a high RDW means they are unusually uneven, which can be an early clue to iron, B12, or folate deficiency, anemia, chronic inflammation, liver or kidney issues, or recent blood loss. A mildly elevated RDW can also be temporary or harmless, which is why it is interpreted alongside hemoglobin, MCV, and your symptoms rather than on its own. There are several important factors that determine whether a flagged RDW needs follow-up testing, and the complete answer below breaks down what each pattern of results can point to.

Red blood cells in your urine, called hematuria, mean blood is present in a urine sample and can point to causes ranging from urinary tract infections, kidney stones, strenuous exercise, or menstruation to kidney disease, an enlarged prostate, or, less commonly, bladder or kidney cancer. Results are usually reported as a number of RBCs per high power field, and even a small amount with no visible color change (microscopic hematuria) is worth evaluating, especially when paired with protein, white blood cells, or nitrites on the same urinalysis. Accompanying symptoms like burning with urination, flank or back pain, frequent urges, fever, or visible pink, red, or cola-colored urine help narrow down the cause, and several important details and risk factors are explained below.

On a blood cell differential, "relative" values describe each type of white blood cell as a percentage of the total white blood cell count, while "absolute" values give the actual number of those cells per microliter of blood. Because a percentage shifts any time the total white blood cell count rises or falls, a relative result can appear abnormal while the true cell numbers are normal, which is why clinicians confirm findings like neutropenia, lymphocytosis, or eosinophilia using absolute counts, calculated by multiplying the percentage by the total white blood cell count. Several factors affect how these numbers should be read, including infection, inflammation, medications, recent stress, pregnancy, and the specific reference ranges used by your lab, so see below to understand the important details behind each value. If your differential flagged a relative or absolute result and you are unsure whether it signals something minor or something worth prompt follow-up, your symptoms matter just as much as the numbers on the page.

Urobilinogen is a compound created when gut bacteria break down bilirubin, and a small amount (roughly 0.2 to 1.0 mg/dL) is normally present in urine. Higher than normal levels can signal liver problems such as hepatitis or cirrhosis, or hemolytic anemia in which red blood cells are destroyed too quickly, while low or absent levels may point to blocked bile ducts, recent antibiotic use, or certain medications. Hydration, sample timing, vitamin C, and lab methods can all shift the number, so there are several important factors to consider before assuming a result is meaningful. See below to understand the full ranges, causes, and follow-up tests your clinician may recommend.

White blood cells in your urine, a finding called pyuria, usually signal inflammation or infection somewhere in the urinary tract, most commonly a bladder infection (UTI), but also kidney infection, kidney stones, sexually transmitted infections, interstitial cystitis, or simple sample contamination. A normal result is typically 0 to 5 WBCs per high-power field, so higher counts, especially alongside nitrites, bacteria, or blood, often point to an active infection that may need antibiotics. Context matters a great deal, including whether you have burning, urgency, fever, or flank pain, because some people show elevated WBCs with no infection at all. There are several important causes and next steps to consider, so see below for the complete answer before assuming your result is a routine UTI.

Most sniffles clear on their own, but certain red flags signal that a runny nose needs urgent care now: trouble breathing or wheezing, chest pain, a stiff neck with high fever, confusion or extreme drowsiness, severe facial or eye swelling and pain, dehydration, coughing up blood, or symptoms that suddenly worsen after seeming to improve. Infants under three months with any fever, older adults, pregnant people, and anyone immunocompromised should be evaluated sooner rather than later.

Yes, low vitamin D can contribute to fatigue, and studies link deficiency to tiredness, muscle weakness, low mood, and poor sleep quality, with many people reporting more energy after levels are corrected. That said, a low result on a blood test does not always explain exhaustion on its own, since anemia, thyroid problems, sleep apnea, depression, infections, and medication side effects can cause the same symptom or occur alongside it. How low your level is, how long it has been low, and whether you have risk factors like limited sun exposure, darker skin, obesity, or malabsorption all change what your result means and how it should be treated. There are several important factors to consider, including safe supplement dosing, when to retest, and warning signs that point to another cause, so review the complete details below before acting on your result.

High monocytes, known as monocytosis, can occasionally signal a blood cancer such as chronic myelomonocytic leukemia or acute monocytic leukemia, but far more often it reflects infections, autoimmune conditions, recovery from illness, chronic inflammation, or stress on the bone marrow. Leukemia is usually suspected only when monocyte elevation is persistent and paired with other abnormal results, such as low red blood cells or platelets, very high white cell counts, or immature cells on a blood smear, along with symptoms like unexplained fatigue, fevers, night sweats, weight loss, easy bruising, or an enlarged spleen. The degree of elevation, how long it lasts, your medications, and your overall clinical picture all change what the number means, so there are several important factors to consider before drawing conclusions.

Yes, low iron can cause fatigue well before a blood test shows anemia, because the body depletes stored iron (ferritin) first while hemoglobin levels still look normal.
