| Issue: | Temozolomide may cause interference in assays using NAD(H) or NADP(H). This has been confirmed in assays for GLDH, CKMB and NH3, depending on the analyser used. It has been determined that the interference occurs at either very low analyte, or too high drug concentrations. These internal investigations were carried out with the therapeutic peak plasma concentration of 0.013 mg/mL Temozolomide. Higher drug concentrations were not systematically tested, because no literature reference for plasma concentrations > 0.013 mg/mL was found. The maximum bias for assays which showed interference at 0.013 mg/mL Temozolomide is shown below: Parameter % bias GLDH + 62% CKMB - 31% NH3 + 36% This interference may results in falsely high or low results. |
