The accuracy, precision, and potential clinical utility of a new whole blood, noninstrumented immunochromatographic assay (AccuLevel) for carbamazepine (CBZ) was evaluated in a multicenter trial including 100 pediatric and 205 adult patients. The AccuLevel assay, a fluorescence polarization immunoassay (FPIA), and high-performance liquid chromatography (HPLC) were used to determine CBZ concentration in samples from 111 female and 194 male patients aged 2-72 years (median 25 years). Mean +/- SD plasma CBZ concentrations in all patients were 7.4 +/- 3.0 micrograms/ml with the AccuLevel assay and 7.5 +/- 2.9 micrograms/ml with FPIA. In 204 patients, the mean concentration determined by the HPLC assay was 7.7 +/- 3.0 micrograms/ml, whereas concentrations determined by the AccuLevel and FPIA assays were 8.0 +/- 3.1 and 8.1 +/- 3.1 micrograms/ml, respectively. Concentrations determined by the AccuLevel and FPIA assays were significantly higher than those quantified by HPLC (p less than 0.05), but not different from each other. In addition, the AccuLevel assay was highly correlated with FPIA (r = 0.97) and HPLC (r = 0.98). Coefficients of variation for the AccuLevel assay at 8 micrograms/ml ranged from 6.8 to 7.5% for the three institutions. We conclude that the AccuLevel assay is a simple, reliable method for determining CBZ concentration in a small volume of whole blood and is an acceptable alternative for assessment of CBZ therapy and individualization of CBZ dosage in the physician's office or emergency room.
