Evaluating patients with signs and symptoms of a connective tissue disease in whom the test for antinuclear antibodies is positive, especially those with signs and symptoms consistent with Sjogren syndrome or lupus erythematosus.
Can SSA antibodies disappear?
This, and the fact that the SSA/Ro antigen may disappear from the nucleus during fixation, commonly produces negative results in the immunofluorescence antinuclear antibody (IF-ANA) screening [11].
Can Sjogren’s antibodies go away?
Secondary Sjogren’s syndrome develops in a person who has another autoimmune disease, usually rheumatoid arthritis or lupus. Treatment for both types is the same. There is no cure for Sjogren’s syndrome, but treatment can address symptoms and improve quality of life.

What does SSA antibody stand for?
SSa antibodies are autoantibodies, which means that they target the body’s own proteins rather than infectious or other foreign protein antigens.
What is a positive anti – SSA antibody?

What is a SSA antibody test?
The anti SSA blood test is one of the testing methods that is available to medical providers to determine the presence of lupus. The SSA antibody is usually found with the SSB antibody, which means there is typically an anti SSB blood test ordered with the anti SSA test. It is not a specific enough test to determine a definitive diagnosis in a majority of patients, but it can be used with other tools and tests to determine if lupus is present.
What is Anti SSA antibody?
