Dihydrotestosterone (DHT), Free, LC/MS/Dialysis

Dihydrotestosterone measurement is used to diagnose 5α-reductase deficiency and for the evaluation of androgen utilization. Dihydrotestosterone is produced by the reduction of testosterone by 5α-reductase in the target organs. Circulating dihydrotestosterone is tightly bound to sex hormone-binding globulin. The free fraction represents the dihydrotestosterone available to act on tissues.
