What does an ANA titer of 1 80 mean?
What does an ANA titer of 1 80 mean?
ANAs can be found in approximately 5% of the normal population, usually in low titers (low levels). These people usually have no disease. Titers of 1:80 or lower are less likely to be significant. (ANA titers of less than or equal to 1:40 are considered negative.)
What is the normal range for antinuclear antibodies?
Normal Results Titres are reported in ratios, most often 1:40, 1:80, 1:160, 1:320, and 1:640. Some, but not all labs will report a titre above 1:160 as positive. Patterns that are reported include, homogeneous, speckled, centromere, and others.
How do I read my ANA profile results?
Your test is positive if it finds antinuclear antibodies in your blood. A negative result means it found none. A positive test doesn’t mean that you have an autoimmune condition. Between 3% and 15% of people with no conditions have antinuclear antibodies.
What is a positive ANA?

What is an Antinuclear Antibody Test? The ANA test is used to detect the presence of antinuclear antibodies (ANA) in blood. In case the presence of the same is detected, it can be used to determine whether you have an autoimmune disorder. The test is generally accompanied by a physical examination and a detailed study of the symptoms.
What does a negative titer mean on a blood test?
A negative test means that certain autoimmune diseases are less likely to be present. However, other tests may still be needed based on your symptoms. The higher the titer, the more likely the result is a “true positive” result, meaning you have significant ANAs and an autoimmune disease.
What does a low Ana titer of 40 mean?
— A low ANA titer (1:40 to 1:80) may be associated with preclinical disease or lack of disease. Patients with the following systemic autoimmune diseases may have a positive test for antinuclear antibodies (ANA): Patients with organ-specific autoimmune diseases may also have a positive test for ANA.
