An evaluation has been carried out of 13 commercial testosterone kits. The within- and between-assay imprecision was found to be unsatisfactory for some kits. Sensitivity and linearity were acceptable for all the kits but several showed concentration-dependent biases to the ALTM or GCMS values. The occurrence of anomalous results and changing performance characteristics of some of the direct kits is also presented.
