Hi, Thanks for writing to HCM. I understand your concern. The antinuclear antibody (ANA) test is used as a primary test to help evaluate a person for autoimmune disorders that affect many tissues and organs throughout the body. It is most often used as one of the tests to help diagnose systemic lupus erythematosus (SLE). A positive ANA test result means that autoantibodies are present. In a person with signs and symptoms, this suggests the presence of an autoimmune disease, but further evaluation is required to assist in making a final diagnosis. By the description of symptoms you are giving it appears that you could have some autoimmune disorder affecting skin, which would require proper evaluation. Kindly consult Physician in this regard for appropriate management. Hope the information provided would be useful. All the best.
