What is the significance of a positive ANA Choice screen and ANA Titer 140?

A positive ANA (antinuclear antibody) screen indicates the presence of autoantibodies that may suggest an autoimmune disorder, such as lupus or rheumatoid Arthritis. An ANA titer of 140, which indicates the dilution at which the antibodies are still detectable, is considered a relatively high level and may warrant further investigation. However, a positive ANA result can also occur in healthy individuals, so clinical correlation with symptoms and additional testing is essential for diagnosis. It's important to consult a healthcare provider for interpretation in the context of the patient's overall health.
