Hey cowgirl,

I know that there can be problems with a tuberculosis skin test if you're on prednisone- it'll turn out negative even if you have it. I imagine the same types of problems might be present with other types of immunosuppresants.

The only thing I could find re. Cellcept and Tuberculosis testing was that TB testing should be done before Cellcept is started.

Sorry that I couldn't be of more help!
Nicky
