Association of bioavailable, free, and total testosterone with insulin resistance: influence of sex hormone-binding globulin and body fat.
OBJECTIVE Previous reports of an association between low testosterone levels and diabetes risk were often confounded by covariation of sex hormone-binding globulin (SHBG) and testosterone measurements. Measurements of bioavailable and free testosterone, more reliable indexes of biologically active testosterone, were examined for their associations with markers of insulin resistance and body fat...
متن کاملEmpirical estimation of free testosterone from testosterone and sex hormone-binding globulin immunoassays.
BACKGROUND The growing interest in measuring blood free testosterone (FT) is constrained by the unsuitability of the laborious reference methods for wider adoption in routine diagnostic laboratories. Various alternative derived testosterone measures have been proposed to estimate FT from either additional assay steps or calculations using total testosterone (TT) and sex hormone-binding globulin...
متن کاملTestosterone, sex hormone-binding globulin, calculated free testosterone, and oestradiol in male vegans and omnivores.
Total testosterone (T), total oestradiol (E2) and sex hormone-binding globulin (SHBG) concentrations were measured in plasma samples from fifty-one male vegans and fifty-seven omnivores of similar age. Free T concentration was estimated by calculation. In comparison with the omnivores, the vegans had 7% higher total T (P = 0.250), 23% higher SHBG (P = 0.001), 3% lower free T (P = 0.580), and 11...
متن کاملAnalog-based free testosterone test results linked to total testosterone concentrations, not free testosterone concentrations.
BACKGROUND Analog-based free testosterone test results, sex hormone binding globulin (SHBG) concentrations, and total testosterone concentrations are somehow related. This study used new experiments to clarify these relationships. METHODS An analog-based free testosterone immunoassay and a total testosterone immunoassay were applied to well-defined fractions of serum testosterone. First, they...
متن کاملSimultaneous determination of free testosterone and testosterone bound to non-sex-hormone-binding globulin by equilibrium dialysis.
We describe a procedure based on equilibrium dialysis that allows the simultaneous determination of free testosterone and testosterone bound to non-sex-hormone-binding globulin (non-SHBG) in plasma. After saturating SHBG with 5 alpha-dihydrotestosterone (DHT) according to a technique recently described, the percentage of free testosterone in the treated and the untreated samples is measured by ...
