Genetic differences in testosterone metabolism can alter the T/E ratio and result in a false-negative test (356). Studies have linked deletion polymorphisms of uridine diphospho-glucurosyl transferase 2B17 (UGT2B17) (the major enzyme for testosterone glucuronidation) with significantly lower T/E https://ecosoberhouse.com/ ratios (357). Because of the high frequency of this polymorphism among East Asian populations, the likelihood […]
