A reversed-phase high-performance liquid chromatographic (HPLC) method with terconazole as internal standard is described for the rapid analysis of ketoconazole in human serum. Except for diazepam no other drug interfered with the analysis. The lowest reproducible limit of the method was 0.05 mg/l. The coefficient of variation of the procedure was less than or equal to 7.5% over a range of ketoconazole concentrations from 1.0 to 10.0 mg/l and less than or equal to 16.75% over a range from 0.05 to 0.5 mg/l. Comparison with a microbiological method showed good correlation.
