An ANA of 1:160 in of itself is nonspecific and has to be considered along with the clinical picture. It is a marker of autoimmune disorder but significant symptoms and signs also have to be present in order to make a diagnosis. Your IgA level is low. The other immunoglobulins are borderline low but these have no bearing on diagnosing Covid. A rheumatologist specializes in autoimmune disease.

An ANA of 1:160, repeatedly positive is not false positive and is suggestive of auto-immune disorder. You immunoglobulin levels are at the low level and depending on other issues could be part of CVID. It would be prudent to consult a rheumatologist. Wish you good health!
