ANA Screen, IFA, with Reflex to Titer and Pattern

Antinuclear Antibodies (ANA) Screen is a test to detect autoantibodies that target components within the cell nucleus. A positive ANA screen suggests the possibility of an autoimmune disorder, such as lupus (SLE), scleroderma, Sjögren's syndrome, or others. However, a positive result can also occur in healthy individuals or due to infections/medications, requiring further evaluation with titer and specific antibody tests.
