ANA PROFILE BY IMMUNOBLOT.

You should get an ANA profile by immunoblot if your ANA screening test is positive, or if you have symptoms of autoimmune disease such as joint pain, facial rash, sun sensitivity, mouth ulcers, dry eyes or mouth, fingers turning white in cold, skin tightening, muscle weakness, or unexplained fatigue and fever.

No special preparation or fasting is required for an ANA profile by immunoblot. Inform your doctor about any medicines, especially steroids, immunosuppressants, hydralazine, procainamide, or isoniazid, as some can affect results or cause drug-induced lupus. Bring your previous ANA (IFA) report and any related test results if available.

No, fasting is not required for an ANA profile by immunoblot. You can eat and drink normally before giving your sample, and the test can be done at any time of day. Inform your doctor about any medicines you take, especially steroids or immunosuppressants, as they may affect interpretation of the results.
