Hello doctor, ige 240, tsh 4.7, fti normal, ana negative , suffering chronic hives, ppd& hepatitis posithives might be due to allery, infectionor autoimmun?

Complicated: For starters, if your PPD is positive, you have either been previously have been exposed to tuberculosis or could have active disease. It also sounds like you are hepatitis + , you need to know what type of hepatitis (a, b, c, or non-a non-b) and whether you are currently positive or just have evidence of past infection. See your doctor. Positive hep and PPD are not due to autoimmune or allergies.
