How is lupus diagnosed if there’s no single test for it?

Diagnosing lupus can be tricky because there isn\u2019t just one test that can tell if someone has it. Instead, doctors look at a mix of things to figure it out.

First, they check for symptoms like joint pain, skin rashes, and tiredness. They also ask about any other health problems and the patient\u2019s family history.

Next, doctors use blood tests to look for certain markers. These tests check for things like antinuclear antibodies (ANA), which are often found in people with lupus. But, having ANA doesn\u2019t always mean someone has lupus, so doctors use this information along with other tests.

Finally, doctors might use criteria from medical guidelines to help them decide. These criteria include a list of symptoms and test results that are commonly seen in lupus patients. By putting all this information together, doctors can make a more accurate diagnosis. This way, they can help people get the right treatment to feel better.
