ANA IFA

You should get an ANA IFA test if you have symptoms of autoimmune disease, such as joint pain or swelling, facial rash, sun sensitivity, mouth ulcers, hair loss, dry eyes or mouth, fingers turning white in the cold, unexplained fever, or fatigue. It is also recommended for unexplained kidney, liver, or blood count abnormalities.

No special preparation or fasting is required for an ANA IFA test. Inform your doctor about any medicines, especially steroids, immunosuppressants, hydralazine, procainamide, isoniazid, or minocycline, as some can affect results or cause drug-induced lupus. Also mention any recent infections, which can sometimes cause a temporary positive result.

No, fasting is not required for an ANA IFA test. 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.
