Drug Patch Tests, Enzyme-linked Immunosorbent Spot Assay (Elispot) and Lymphocyte Transformation Tests in Patients With Severe Cutaneous Adverse Reaction to Drugs (SCARs)

This study also investigate in Enzyme-linked immunosorbent spot assay (ELIspot) and lymphocyte transformation test. We also trying to prove the correlation among result of drug patch tests, ELIspot and LTT.
