The anion gap is a calculated value from a basic metabolic panel that estimates the balance between positively and negatively charged particles (electrolytes like sodium, chloride, and bicarbonate) in your blood, and doctors check it to detect hidden acid-base disorders. A high anion gap often points to metabolic acidosis from causes such as diabetic ketoacidosis, lactic acidosis, kidney failure, or certain poisonings, while a low or normal gap can suggest diarrhea, kidney tubule problems, or lab-related issues like low albumin. Normal ranges vary by laboratory and by whether potassium is included in the calculation, so a slightly abnormal result is not always meaningful on its own. Your symptoms, medications, hydration status, and other lab values all change how the number should be interpreted, and several important factors are explained below. If you are trying to make sense of an abnormal anion gap or symptoms like confusion, rapid breathing, nausea, extreme thirst, or fatigue, a free, instant online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are experiencing, see which conditions may fit, and decide whether you need urgent care or a routine follow-up conversation with your doctor.

AST (aspartate aminotransferase) is an enzyme found mainly in the liver, heart, muscles, and red blood cells, and it is measured in a blood panel to check for tissue or liver damage. A normal range is roughly 8 to 33 U/L, so a high AST level can signal liver conditions like hepatitis or fatty liver disease, but it may also reflect muscle injury, intense exercise, certain medications, or heart problems. Because AST alone cannot pinpoint the cause, doctors compare it to ALT and other results, and several important factors are explained below. If your results came back elevated, a free, instant <a href="https://ubiehealth.com/">symptom check</a> can help you connect your lab findings with what you are actually feeling and clarify whether you need urgent care, a follow-up test, or simply a lifestyle adjustment. It takes only a few minutes, is based on medical research, and gives you clear next steps before your next appointment. Last reviewed for medical accuracy: 10/01/2025

AST (aspartate aminotransferase) is an enzyme found mostly in the liver, heart, muscles, and red blood cells, and it leaks into the bloodstream when those tissues are stressed or damaged, so a high result often points to liver injury from alcohol, fatty liver, hepatitis, or certain medications, as well as to muscle strain, intense exercise, or heart issues. Several factors shape what your number actually means, including your AST to ALT ratio, other liver values, recent workouts, supplements, and underlying conditions, and details below explain how each one changes the picture. Mildly elevated AST is common and often reversible, while sharply high levels or symptoms such as jaundice, dark urine, abdominal pain, or unusual fatigue deserve prompt attention. Because a single lab value rarely tells the whole story, a free, instant, online <a href="https://ubiehealth.com/">symptom check</a> can help you connect your AST result to what you are feeling and clarify which possibilities fit best. It takes just a few minutes, costs nothing, and gives you a clearer, more organized starting point for your next conversation with a clinician. Last reviewed for medical accuracy: 10/01/2026

**BASO** on a complete blood count measures basophils, the smallest subset of white blood cells, which release histamine and help drive allergic and inflammatory responses; results are reported as a percentage (usually about 0 to 2 percent) or an absolute count (roughly 0 to 0.2 x 10⁹/L). A high result, called basophilia, can reflect allergies or asthma, chronic inflammation such as inflammatory bowel disease or rheumatoid arthritis, an underactive thyroid, certain infections, or less commonly a bone marrow condition like chronic myeloid leukemia. A low or zero result is often harmless, but may follow an acute allergic reaction, severe stress, steroid treatment, or an overactive thyroid. Because one BASO number rarely means much alone, your other CBC values, medications, and symptoms change how it should be read, and there are several important details to consider below before drawing conclusions. If you are trying to make sense of a flagged BASO result or symptoms like persistent itching, rashes, fatigue, night sweats,

Basophils are the rarest type of white blood cell, normally making up less than 1% to 2% of your total white blood cell count, and they release histamine and other chemicals that drive allergic reactions, inflammation, and blood clot regulation. A high basophil count, called basophilia, is generally defined as more than about 200 basophils per microliter and can point to allergies or asthma, chronic inflammation such as inflammatory bowel disease or rheumatoid arthritis, an underactive thyroid, infections, or less commonly bone marrow disorders like chronic myeloid leukemia. Mildly elevated results are often harmless or temporary, so context matters, including your other blood cell lines, symptoms, and medications; see below to understand which patterns deserve prompt follow-up and which do not. Because an abnormal basophil level is a clue rather than a diagnosis, the most useful next step is organizing your symptoms so you and your doctor can narrow the possibilities quickly.

BASOS stands for basophils, a small type of white blood cell that makes up less than 1% to 2% of your total white count and helps drive inflammation and allergic responses. A high basophil count, called basophilia, can point to allergies, chronic inflammation, hypothyroidism, infections, or less commonly blood disorders such as myeloproliferative neoplasms or chronic myeloid leukemia. Because the number alone rarely tells the full story, doctors interpret it alongside your other CBC values, symptoms, and medical history, and several important factors are explained below.

Bilirubin is a yellow-orange waste product created when red blood cells break down, and a healthy liver processes it so it can leave the body through stool and urine. A blood test typically reports total bilirubin along with direct (conjugated) and indirect (unconjugated) fractions, with normal adult total levels generally falling around 0.1 to 1.2 mg/dL. A high result may reflect rapid red blood cell breakdown, liver conditions such as hepatitis or cirrhosis, bile duct blockage from gallstones, certain medications, or a harmless inherited trait called Gilbert syndrome, and it can be accompanied by jaundice, dark urine, pale stools, itching, or fatigue. Because some mild elevations are benign while others signal urgent liver or gallbladder problems, which fraction is elevated and which symptoms are present both matter, so review the complete explanation below before interpreting your numbers. If you are trying to understand an elevated bilirubin level or new symptoms, a free, instant online <a href="https://ubiehealth.com/">symptom check</a> can help you organize what you are experiencing, see which conditions align with your pattern, and decide whether to seek urgent care, schedule a visit, or keep monitoring.

A high platelet count (thrombocytosis) usually falls into two groups: reactive causes, such as infection, inflammation, iron deficiency anemia, recent surgery, injury, or removal of the spleen, and clonal bone marrow disorders like essential thrombocythemia or other myeloproliferative neoplasms. Reactive cases are far more common and often resolve once the trigger is treated, while bone marrow causes can raise the risk of clotting, stroke, or bleeding and need ongoing hematology care. Certain clues matter most, including how high the count is, whether it stays elevated on repeat testing, your age, and symptoms such as headaches, burning in the hands or feet, unexplained bruising, or an enlarged spleen. There are several important distinctions and warning signs to consider, so see below to understand more. Because the same lab result can mean something harmless or something that needs prompt treatment, the fastest way to make sense of your numbers is to look at them alongside your symptoms and history. A free, instant, online <a href="https://ubiehealth.com/">symptom check</a> walks you through targeted questions in just a few minutes, highlights the conditions most consistent with what you are experiencing, and suggests which type of doctor to see and how soon.

High creatinine can stem from harmless, temporary factors such as intense exercise, a high-protein or creatine-supplemented diet, dehydration, large muscle mass, or certain medications that block creatinine secretion without harming the kidneys. It can also signal more serious issues, including acute or chronic kidney disease, reduced blood flow to the kidneys, urinary blockage, infection, or damage from NSAIDs and other drugs. Because a single elevated reading rarely tells the whole story, trends over time, your eGFR, urine protein, and symptoms like swelling, fatigue, or changes in urination matter; the important distinctions are explained below. Since harmless and dangerous causes can look identical on a lab report, a few minutes of structured questions can help you see which pattern fits your situation and how soon you should be evaluated.

High platelet counts (thrombocytosis) fall into two groups: reactive causes such as infection, inflammation, iron deficiency, recent surgery, trauma, spleen removal, or certain cancers, and clonal bone marrow disorders like essential thrombocythemia, polycythemia vera, or myelofibrosis. Reactive thrombocytosis usually resolves once the trigger is treated and rarely needs platelet-lowering therapy, while clonal causes may require aspirin or drugs such as hydroxyurea to prevent clots and bleeding. Risk factors including age over 60, prior blood clots, cardiovascular disease, and platelet counts above 1,000,000 per microliter change how urgently treatment is needed. Warning signs like chest pain, numbness, severe headache, vision changes, or unusual bruising deserve prompt medical attention. There are several important factors to consider, so review the complete answer below before drawing conclusions about your own results.

Low potassium (hypokalemia) is most often caused by fluid and electrolyte loss from vomiting, diarrhea, heavy sweating, or diuretics and other medications, though hormonal conditions like hyperaldosteronism, kidney disorders, low magnesium, poorly controlled diabetes, alcohol use, and rarely inadequate dietary intake can also be responsible. Mild cases tied to a short illness or a single medication may correct on their own, while moderate to severe drops, or any case causing muscle weakness, cramping, constipation, palpitations, or irregular heart rhythm, require prompt medical treatment and investigation of the underlying cause. Several factors determine which causes are urgent and which can be monitored, and see below to understand the full details, including the warning signs that point to a cardiac risk. Because the symptoms of low potassium overlap with many other conditions, and the right next step depends on what is driving your levels down, it helps to organize your symptoms before you speak with a clinician.

Low potassium, or hypokalemia, most often develops from excess losses through vomiting, diarrhea, laxative overuse, or diuretics, though poor intake, alcohol use, magnesium deficiency, kidney disorders, and hormonal conditions like hyperaldosteronism can also drive levels down. Correction depends on severity and cause: mild cases may respond to potassium-rich foods and oral supplements, while significant deficits often require prescribed potassium chloride, magnesium replacement, and treatment of the underlying trigger, with severe cases needing IV potassium and heart monitoring. Several important factors affect which approach is safe for you, including your kidney function, medications, and whether symptoms like muscle weakness, cramps, or palpitations are present, so see below for the complete details. If you are noticing fatigue, cramping, irregular heartbeats, or unexplained weakness, guessing at the cause can delay care that matters, since potassium imbalances can affect the heart.

Chloride is an electrolyte measured in a blood test (often as part of a basic metabolic panel or electrolyte panel) to show how well your body balances fluids, acids, and bases, with typical adult levels falling around 96 to 106 mEq/L. High chloride can point to dehydration, kidney problems, or metabolic acidosis, while low chloride may signal prolonged vomiting, heart failure, lung disease, or Addison disease, though results are rarely interpreted alone. Several factors influence your number, including medications, IV fluids, and your sodium, potassium, and bicarbonate levels, so see below to understand what your specific result may mean.

Monocytes are a type of white blood cell, and a count above roughly 800 to 1,000 monocytes per microliter of blood, or more than about 10% of your total white blood cells, is generally considered high, a condition called monocytosis. Common causes include recovery from infection, chronic viral or bacterial infections such as tuberculosis, autoimmune and inflammatory conditions like lupus or inflammatory bowel disease, and less often blood disorders such as leukemia or myeloproliferative disease. Because lab reference ranges vary and a mildly elevated result can be harmless while a persistent one may need follow-up, the specific number matters less than the pattern and your other symptoms. There are several important factors to consider, including which other blood values are abnormal and how long the elevation has lasted, so see below to understand more.

A troponin level is considered high when it rises above the 99th percentile of your lab's reference range, often around 14 ng/L for high-sensitivity troponin T or roughly 0.04 ng/mL for standard assays, though cutoffs differ by lab, sex, and assay type. Sharply elevated or rising results across repeat tests usually point to heart muscle injury such as a heart attack, while mild or stable elevations can stem from kidney disease, sepsis, pulmonary embolism, myocarditis, heart failure, atrial fibrillation, or even intense exercise. Because the number alone never tells the full story, clinicians interpret it alongside symptoms, ECG findings, and the trend over several hours, and there are several important factors to consider before drawing conclusions, explained in detail below.

HCT (hematocrit) measures the percentage of your blood volume made up of red blood cells, with typical ranges around 38.3% to 48.6% for men and 35.5% to 44.9% for women. A low HCT can point to anemia, iron or vitamin deficiency, blood loss, kidney disease, or pregnancy, while a high HCT may reflect dehydration, lung or heart conditions, smoking, high altitude living, or polycythemia vera. Because normal ranges vary by age, sex, altitude, and lab, your result must be read alongside hemoglobin, red cell count, and your symptoms, so there are several important factors to consider below before drawing conclusions. Since the same number can mean something very different depending on your history, medications, and hydration status, a free, instant <a href="https://ubiehealth.com/">symptom check</a> can help you connect your HCT result to what you are actually experiencing.

Hemoglobin is the iron-rich protein inside red blood cells that carries oxygen from your lungs to your tissues and returns carbon dioxide for exhalation, and its level on a complete blood count reflects how well your blood performs that job. Normal values typically range from about 13.5 to 17.5 g/dL for adult men, 12.0 to 15.5 g/dL for adult women, with different reference ranges for children, pregnancy, and older adults, though labs vary slightly in how they define normal. Low readings may point to anemia, blood loss, or nutritional deficiencies, while high readings can reflect dehydration, smoking, lung or heart conditions, or living at high altitude. Several factors influence your result, including age, sex, altitude, hydration, and medications, so see below to understand more before drawing conclusions from a single number. If your hemoglobin result looks off or you are noticing fatigue, shortness of breath, dizziness, or pale skin, a free, instant online <a href="https://ubiehealth.com/">symptom check</a> can help you connect your numbers to your symptoms and decide whether to monitor at home, call your doctor, or seek urgent care.

Hgb is the abbreviation for hemoglobin, the iron-rich protein inside red blood cells that carries oxygen from your lungs to the rest of your body and returns carbon dioxide for exhaling. Normal results typically range from about 13.5 to 17.5 g/dL for adult men and 12.0 to 15.5 g/dL for adult women, with different reference ranges for children, infants, and pregnancy, so a low Hgb may point to anemia, blood loss, or nutrient deficiency, while a high Hgb can reflect dehydration, smoking, altitude, lung disease, or a bone marrow disorder. Because age, sex, hydration, altitude, medications, and each laboratory's own reference range all shift what "normal" means for you, a single number rarely tells the whole story. There are several important factors to consider, and the complete explanation below covers the ranges, causes, and symptoms that help put your result in context.

High chloride on a blood test, known as hyperchloremia, means the level of chloride in your blood is above the normal range of roughly 96 to 106 mEq/L, often signaling dehydration, an acid-base imbalance, or a fluid and electrolyte shift rather than a disease on its own. Common causes include dehydration from vomiting, diarrhea, or inadequate fluid intake, kidney disorders such as renal tubular acidosis, metabolic acidosis, excessive IV saline, Cushing syndrome, hyperparathyroidism, and certain medications like diuretics, corticosteroids, and acetazolamide. Symptoms may be absent or subtle, but can include excessive thirst, dry mouth, fatigue, weakness, high blood pressure, rapid breathing, or confusion when the imbalance is significant. Because chloride is almost always interpreted alongside sodium, potassium, bicarbonate, and the anion gap, a single high value rarely tells the full story, and mild elevations are frequently temporary. There are several important factors and red flags to consider, so see below to understand more about what your result may mean and when to seek care.

Low hemoglobin on a blood test, also called anemia, means your red blood cells are carrying less oxygen than your body needs, typically flagged below roughly 13.5 g/dL in men and 12 g/dL in women. Causes range from iron, vitamin B12, or folate deficiency and blood loss (heavy periods, ulcers, gastrointestinal bleeding) to pregnancy, chronic kidney disease, ongoing inflammation, thyroid disease, bone marrow disorders, and inherited conditions such as thalassemia or sickle cell. How low the number is, how fast it dropped, and which other values are abnormal (MCV, ferritin, reticulocytes) all change what it means for you, and those important distinctions are explained below.

Low lymphocytes, called lymphocytopenia or lymphopenia, means your blood test found fewer lymphocytes (a type of white blood cell that fights infection) than expected, usually under about 1,000 cells per microliter in adults, which can signal a weakened immune response. Frequent causes include recent viral infections such as influenza, COVID-19, or HIV, bacterial infections like tuberculosis, corticosteroids, chemotherapy or radiation, severe physical stress, malnutrition, heavy alcohol use, autoimmune diseases such as lupus, and less commonly blood and lymph disorders or inherited immune deficiencies. Mildly low counts are often temporary and return to normal on a repeat test, while persistently low counts paired with fevers, recurrent infections, night sweats, swollen lymph nodes, or unexplained weight loss call for prompt evaluation. There are several important factors to consider, including your medications, recent illnesses, and your other blood count values, all detailed below.

MCH (mean corpuscular hemoglobin) measures the average amount of hemoglobin inside each red blood cell, with a typical adult range of about 27 to 33 picograms. Low MCH often points to iron deficiency anemia, chronic blood loss, or thalassemia, while high MCH can signal vitamin B12 or folate deficiency, liver disease, alcohol use, or certain thyroid problems. A slightly abnormal result on its own is not a diagnosis, since MCH is interpreted alongside MCV, hemoglobin, hematocrit, and red cell distribution width. There are several important factors that change what your number means, including medications, pregnancy, and recent illness, so see below to understand more. Because MCH shifts for many different reasons, the fastest way to make sense of your result is to look at it together with your symptoms, such as fatigue, pale skin, shortness of breath, tingling hands, or dizziness.

MCV (mean corpuscular volume) is a standard part of a complete blood count that measures the average size of your red blood cells, usually reported in femtoliters with a typical adult range of about 80 to 100 fL. A low MCV (microcytic) often points to iron deficiency or thalassemia, while a high MCV (macrocytic) can suggest vitamin B12 or folate deficiency, liver issues, thyroid problems, or heavy alcohol use, and a normal MCV does not always rule out anemia. Because MCV is interpreted alongside hemoglobin, hematocrit, MCH, and RDW, the same number can mean very different things from person to person, so there are several important factors to consider before drawing conclusions, explained in detail below.

Monocytes are a type of white blood cell made in your bone marrow that circulate in your blood before moving into tissues, where they mature into macrophages and dendritic cells. They work as frontline defenders, engulfing bacteria, viruses, fungi, and dead cells, triggering inflammation, and helping other immune cells recognize threats, while a monocyte count (typically 2 to 8 percent of your white blood cells) signals how actively your immune system is responding. A high count, called monocytosis, can point to chronic infection, autoimmune disease, inflammatory bowel conditions, or certain blood cancers, while a low count, or monocytopenia, may follow acute infections, chemotherapy, or bone marrow problems. There are several factors that influence what your result actually means, including recent illness, medications, stress, and whether other blood values are also abnormal, so see below to understand more before drawing conclusions.

MPV (mean platelet volume) measures the average size of your platelets, the cells that help your blood clot, and it is reported as part of a standard complete blood count. High MPV can mean your bone marrow is producing larger, younger platelets more rapidly, which may be linked to conditions such as immune thrombocytopenia, inflammatory or heart-related disease, or recovery from blood loss, while low MPV suggests smaller platelets and may point to bone marrow suppression, certain inherited platelet disorders, or chemotherapy effects. Results are interpreted alongside your platelet count, other blood values, and symptoms, so there are several important factors to consider before drawing conclusions, as explained below. Because an abnormal MPV rarely means much on its own, the fastest way to learn what your result could be signaling for you is to review your actual symptoms.

NEUT stands for neutrophils, the most common type of white blood cell and your immune system's first responder against bacterial and fungal infections, reported as an absolute count (typically about 1,500 to 8,000 cells per microliter) or as a percentage of total white cells (roughly 40 to 70 percent). High neutrophils, called neutrophilia, often point to bacterial infection, inflammation, physical or emotional stress, smoking, pregnancy, steroid or growth-factor medications, and less commonly bone marrow disorders such as leukemia. Low neutrophils, called neutropenia, can follow viral infections, chemotherapy or certain drugs, autoimmune conditions, vitamin B12 or folate deficiency, and genetic or marrow problems, and raise your risk of serious infection when counts fall below 1,000. Because a single NEUT value means little without your other blood counts, symptoms, medications, and timing, there are several important factors to consider before drawing conclusions, explained in detail below.

Neutrophils are the most common type of white blood cell, acting as your immune system's first responders against bacterial and fungal infections, and a blood test reports them as an absolute neutrophil count (typically about 1,500 to 8,000 cells per microliter) or as a percentage of total white blood cells (roughly 40 to 60 percent). A high count, called neutrophilia, often points to infection, inflammation, physical stress, smoking, or certain medications like steroids, while a low count, called neutropenia, can reflect viral illness, autoimmune conditions, vitamin B12 or folate deficiency, chemotherapy, or bone marrow problems.
