PURPOSE: The usefulness of the lymphocyte stimulation test (LST) was examined in patients who arose side effects to antituberculosis drugs. METHODS: The usefulness of LST was examined in 36 patients from January, 1999 to July, 2002. RESULTS: There were 11 LST positive patients, and the LST positive rate was 30.6%. The causing agents determined by the LST positive patients were INH in 7, RFP in 3 and EB in one. The sensitivity of LST was 46.2% and the specificity of LST was 76.6%. CONCLUSION: LST positive rate of antituberculosis drugs was low and it was difficult to determine the causing drugs by LST.
