Order SHBG (Sex Hormone Binding Globulin) Levels Blood TestSex Hormone Binding Globulin (SHBG) is a liver-produced glycoprotein that binds testosterone, dihydrotestosterone, and estrogens in the bloodstream. This blood test measures the concentration of SHBG in serum, providing information that helps interpret the amount of circulating sex hormones that remain unbound and biologically available to tissues.
About SHBG (Sex Hormone Binding Globulin) Levels Blood Test in San Juan
SHBG regulates the fraction of sex hormones that circulate freely in the blood.
A large proportion of testosterone, dihydrotestosterone, and estradiol travels through the bloodstream attached to SHBG or albumin. Only the unbound, or free, portion is able to enter cells and exert hormonal effects, so the amount of SHBG present influences how much hormone is available to target tissues.
Because SHBG binds sex hormones with differing affinities, changes in its concentration can shift the balance between bound and free hormone. When SHBG is high, a greater share of total hormone is bound and less is free; when SHBG is low, more hormone circulates in the unbound state. This is why SHBG is often measured alongside total testosterone or estradiol rather than interpreted in isolation.
SHBG levels are influenced by a range of physiological and clinical factors, including thyroid function, liver status, body composition, age, and certain medications. The test itself requires a standard blood sample, and results are typically reported as a numeric concentration with a reference range established by the performing laboratory.
