      Validation of androgen enzyme immunoassays (EIA) using purified antiserum with a high cross-reactivity for testosterone and 5α-dihydrotestosterone in polar bear urine (PBU) has previously been reported. However, the cross-reactivity of this antiserum with urinary testosterone metabolites was not determined....
