If you’ve been told that you have a positive ANA test result, it’s important to understand what that means. ANA is short for anti-nuclear antibody, and this type of blood test measures the level of these antibodies in your system. While a positive ANA test result doesn’t automatically mean you have a specific disease, it can be an indicator of certain conditions. Here we’ll explain what an ANA test is, what the possible implications are if you have a positive result, and how to get more information about this type of testing.


What is an ANA Test for Antinuclear antibodies?

The ANA test is used to detect the presence of antinuclear antibodies (ANA) in a person’s blood. ANA are proteins produced by the body’s immune system that can attach to healthy cells and tissues, leading to inflammation and damage.


ANA are often associated with autoimmune diseases, such as lupus and rheumatoid arthritis. However, the presence of ANA does not necessarily mean that a person has an autoimmune disease. In fact, ANA are present in some people who do not have any known health problems.


If ANA are detected through the ANA test, it is important to follow up with additional testing and/or specialist care to determine if an autoimmune disease is present and, if so, to begin treatment. ANA testing is just one tool that can be used to help diagnose autoimmune diseases.


Which Autoimmune Diseases have High ANA?

There are a number of autoimmune diseases that are associated with high ANA levels. These include lupus, rheumatoid arthritis, scleroderma, and Sjögren’s syndrome. ANA testing can help to confirm a diagnosis in these cases. ANA levels may also be elevated in other conditions, such as viral infections, but this is usually not indicative of an autoimmune disease.


What do ANA test results mean?

ANA test results are reported as positive or negative. A positive ANA test indicates the presence of antinuclear antibodies in the blood. This does not necessarily mean that an autoimmune disease is present, but it is one indicator that may be used along with other tests and symptoms to make a diagnosis. A negative ANA test means that no antinuclear antibodies were detected.


What is the ANA titer?

The ANA titer is a measure of the concentration of ANA in the blood. It is reported as a ratio, such as 1:160 or 1:320. A higher ratio indicates a higher concentration of ANA. ANA levels can fluctuate over time, so the titer may be repeated to see if it has changed.

How is an ANA test performed?

An ANA test is a blood test. A small sample of blood will be drawn from a vein in the arm and sent to a laboratory for analysis.


What are the risks of an ANA test?

There are no risks associated with an ANA test.


What are the limitations of ANA testing?

ANA testing is just one tool that can be used to help diagnose autoimmune diseases. It is not diagnostic on its own, and other tests may be needed to confirm a diagnosis. ANA levels may also be elevated in conditions other than autoimmune diseases, such as viral infections. ANA testing is also not used to monitor the progression or treatment of autoimmune diseases.

Which Doctor should I show my ANA test results to?

If you have ANA test results that are positive, it is important to follow up with a rheumatologist. ANA testing can be done as part of a routine blood workup or if autoimmune disease is suspected. ANA testing is used to help diagnose autoimmune diseases, such as lupus erythematosus (LE) and rheumatoid arthritis (RA).


ANA levels may be elevated in healthy individuals; therefore, the ANA result must be interpreted in the clinical context. ANA testing is not recommended for healthy individuals who do not have symptoms suggestive of an autoimmune disease.


Can I have an autoimmune disease with a negative ANA test?

The ANA test is not specific for any one autoimmune disease. It is often used as a screening test to help diagnose autoimmune diseases such as lupus erythematosus, Sjögren’s syndrome, and rheumatoid arthritis. However, a positive ANA test does not necessarily mean that you have an autoimmune disease. ANA tests can be positive in healthy people, and ANA test results can vary depending on the laboratory that performs the test.


If you have symptoms suggestive of autoimmune disease and a positive ANA test, your doctor may order additional tests to help confirm the diagnosis. These could include tests for specific autoantibodies or other blood tests, imaging studies, or biopsies. 


Even if you have a negative ANA test, it is still possible to have an autoimmune disease. ANA testing is not perfect, and there are other causes of autoimmune diseases besides autoantibodies. If you have symptoms suggestive of an autoimmune disease, your doctor will likely order additional tests to help make a diagnosis.


If my autoimmune disease improves, will a repeat ANA test become negative?

Autoimmune diseases are chronic conditions in which the body mistakenly attacks itself. ANA tests are used to help diagnose autoimmune diseases, as well as to track the progress of these conditions.


If a person’s autoimmune disease improves, it is possible that their ANA test will become negative. However, this is not always the case, and some people may continue to have a positive ANA test even after their disease has gone into remission. ANA tests are not always accurate, and further testing may be necessary to confirm a positive response to their treatments.
