Order SHBG (Sex Hormone Binding Globulin) Levels Blood TestSex Hormone Binding Globulin (SHBG) is a liver-produced glycoprotein that binds testosterone, dihydrotestosterone, and estradiol in the bloodstream. Because only unbound hormone is free to enter tissues and exert biological effects, SHBG is a key determinant of how much active hormone is available to the body. This blood test measures the concentration of SHBG in serum, providing information that helps interpret total hormone levels and estimate free hormone fractions.
About SHBG (Sex Hormone Binding Globulin) Levels Blood Test in Bangor
SHBG regulates the distribution of sex hormones between bound and unbound states.
SHBG is synthesized primarily in the liver and circulates in serum, where it binds testosterone, dihydrotestosterone, and estrogens with varying affinity. Roughly half to two-thirds of circulating testosterone is typically bound to SHBG, while the remainder is bound loosely to albumin or circulates unbound. The unbound and albumin-bound fractions together constitute the bioavailable hormone pool.
Because SHBG influences how much hormone remains free, its concentration can affect the interpretation of total hormone measurements. Elevated SHBG tends to lower the free fraction of testosterone and estradiol for a given total level, while reduced SHBG tends to raise it. Conditions such as thyroid disorders, liver disease, obesity, and changes in estrogen or androgen balance can alter SHBG concentrations.
Measuring SHBG alongside total testosterone or estradiol allows calculation of free hormone indices and provides a more complete picture of endocrine status. Results are typically interpreted by a clinician in the context of symptoms, other hormone tests, and the individual's overall health.
