What is an ANA test for lupus?
The antinuclear antibody (ANA) test is commonly used to look for autoantibodies that attack components of your cells’ nucleus, or “command” center, triggering autoimmune disorders like lupus.
What does it mean if your ANA is positive?
In most cases, a positive ANA test indicates that your immune system has launched a misdirected attack on your own tissue — in other words, an autoimmune reaction. But some people have positive ANA tests even when they’re healthy.
What happens after a positive ANA test?
A positive result on an ANA test may help a doctor to diagnose an autoimmune disorder. However, if after a positive result neither the person nor the doctor recognizes any signs or symptoms, the medical team may disregard the result.
What to do after positive ANA test?
Talk with your doctor about what your levels mean and how your symptoms may be explained by the presence of ANA. If your ANA test comes back positive, your doctor will need to run more tests in order to help determine if the results are related to a specific condition. The ANA test is especially helpful in diagnosing lupus.
What causes elevated Ana titer?
The normal titer of antinuclear antibody is 1:40; higher titers of this autoantibody can indicate that a person is affected by an autoimmune diseases. Some of the conditions that can cause a high ANA titer include Lupus, scleroderma, and rheumatoid arthritis (WebMD).
What is high ANA test results?
Some people with autoimmune diseases may get a negative test result for ANA but positive for other antibodies. A positive ANA test means that you have high levels of ANA in your blood. A positive ANA test is usually reported as both a ratio (called a titer) and a pattern, such as smooth or speckled.
What does a high Ana level mean?
An ANA panel helps determine the level of ANA in your blood. You may have an autoimmune disorder if the level is high. However, conditions such as infections, cancer, and other medical problems can also result in a positive ANA test.
