How many times does the ana test is positive in a lupus patient? how long does it stay positive? and does the test needs to be repeated over the years

ANAs are complex : ANA panels are complex and require thorough clinical correlation for maximum predictive value of disease. Patterns of positivity and negativity may sometimes need to be assessed overtime to make a specific diagnosis. Stay vigilant and follow up.

Positive ANA test: The ANA once positive, usually stays positive for life. The ANA can be helpful to diagnose an autoimmune disease like lupus. Once lupus is diagnosed, however, there is no need to repeat the test.
