Testosterone, dihydrotestosterone and estrogens circulate in serum bound to Sex Hormone Binding Globulin (SHBG). SHBG concentrations are increased in pregnancy, hyperthyroidism, cirrhosis, oral estrogen administration and by certain drugs. Concentrations are decreased by testosterone, hypothyroidism, Cushings syndrome, acromegaly and obesity.
Inform your doctor if you are on any medications, have any allergies or underlying medical conditions before your SHBG. Your doctor will give specific instructions depending on your condition on how to prepare for SHBG.
