The ANA (antinuclear antibody) blood test checks for antibodies that attack the body's own cells. It is often ordered when a doctor suspects an autoimmune condition, such as lupus or rheumatoid arthritis, based on symptoms like joint pain, rash, or fatigue.
What it measures
- Antinuclear antibodies (ANA) — The main marker; a positive result means antibodies that target the cell nucleus were found.
- Titer — How diluted the blood can be before antibodies are no longer detected; higher titers are more significant.
- Pattern — The shape antibodies make under a microscope, which can hint at specific autoimmune conditions.
Who it is for
A primary care doctor or rheumatologist typically orders this test when a patient has unexplained symptoms that could be autoimmune.
Preparation
No fasting or special preparation is needed. Tell your doctor about any medications you take, as some can affect results.
Results and what they mean
Results are reported as positive or negative, often with a titer and pattern. A positive result does not confirm a disease, and a negative result does not rule one out; a clinician interprets the results alongside your symptoms and other tests. This is general information, not medical advice.
