Order SHBG (Sex Hormone Binding Globulin) Levels Blood TestSHBG, or sex hormone binding globulin, is a protein produced primarily by the liver that attaches to sex hormones in the bloodstream. This blood test measures how much SHBG is present in serum. Because testosterone, dihydrotestosterone, and estrogens travel largely bound to this protein, SHBG levels influence how much hormone remains free and biologically active.
About SHBG (Sex Hormone Binding Globulin) Levels Blood Test in Rockwall
SHBG is more than a carrier protein; it is a key variable in interpreting sex hormone status.
Testosterone, dihydrotestosterone, and estrogens circulate in serum bound to SHBG and, to a lesser extent, to albumin. Hormone molecules bound to SHBG are not readily available to tissues, while the unbound fraction is considered free and active. Measuring SHBG alongside total testosterone allows the free or bioavailable testosterone fraction to be estimated.
SHBG production is influenced by several factors. Thyroid hormone levels, liver function, body composition, insulin, and age can all shift SHBG concentrations. Estrogens tend to raise SHBG, whereas androgens tend to lower it. As a result, an SHBG result is rarely interpreted alone; it is read in the context of the hormones it binds and the clinical picture.
The test is performed on a blood sample, typically from a vein. Preparation follows the lab's instructions, and results are generally reported within a few business days. Because SHBG values depend on the method used, trends are best compared using the same laboratory over time.
