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.

FAQ
Frequently asked questions
What does a positive ANA test mean?
A positive result means that antinuclear antibodies were found in your blood. It does not by itself mean you have an autoimmune disease, because these antibodies can also be present in healthy people. Your clinician will consider your symptoms, medical history, and other test results to understand what a positive result means for you.
Can the ANA test diagnose lupus or another autoimmune disease?
No, the ANA test alone cannot diagnose lupus or any other condition. It is one tool that may support a diagnosis when combined with clinical signs, symptoms, and additional testing. Some people with autoimmune diseases have a negative ANA, and many people without autoimmune diseases have a positive one.
Do I need to fast before an ANA blood test?
Fasting is usually not required for an ANA test. However, if you are having other tests at the same time, you may need to fast for those. Always check with the laboratory or your clinician about any preparation instructions for your specific situation.
How long does it take to get ANA test results?
Results are commonly available within a few business days, but timing can vary by laboratory and how the test is performed. Your clinician's office will let you know when to expect your results. Ask the collection site if you need a more specific timeframe.
