This test uses liquid chromatography/mass spectrometry to accurately measure free estradiol, the portion of estradiol that is not bound by SHBG. NOTE: This test is a send out test to Quest's Nichols Institute San Juan Capistrano.  Testing schedule is Mon and Wed.  Reports are available within 4-14 days from the time the specimen is received at the send out testing lab

Note: Studies on the effect of free estradiol blood levels in men are lacking. Only one reference concludes that free estradiol, not total, maybe a better predictor of bone density in older men (Bone Miner Res 2005;20:1334–1341.)

Some physicians are starting to use this test in men with low Sex Hormone Binding Globulin with symptoms of high estradiol.
