What this test is

The antinuclear antibody test looks for antibodies that bind to structures inside the cell nucleus. These antibodies are more common in certain autoimmune diseases, but they can also appear in people without any illness. The test is one piece of information and is interpreted alongside symptoms and other findings.

What it measures

  • Antinuclear antibodies (ANA) — Presence and amount of antibodies that target the cell nucleus
  • ANA titer — The highest dilution at which antibodies are still detected
  • ANA pattern — The staining pattern seen under the microscope, such as homogeneous or speckled

What the test involves

A health professional collects a small sample of blood, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.

Why it is often ordered

A clinician may order an ANA test when someone has symptoms that could suggest an autoimmune condition, such as persistent joint pain, skin changes, or unexplained fatigue. It is also sometimes used to help monitor a known autoimmune condition, but it is not a stand-alone diagnostic test.

Preparation

In most cases, no special preparation is needed for an ANA blood test. Follow the instructions provided by the collection site or laboratory, as their requirements may vary.

How results are reported

Results are typically reported as a titer and a pattern, with a note about whether the result is considered positive or negative based on the laboratory's reference range. Reference ranges and reporting methods can differ between laboratories, so your clinician will interpret the result in the context of your overall health.

Before you go

  • Whether any special preparation is needed for your test
  • How and when you will receive your results
  • If other tests will be done at the same time
