Free Estradiol (Sensitive)
This test measures the free (unbound to SHBG or albumin) estradiol in blood. The test is performed using liquid chromatography/mass spectrometry (LC/MS).
This test uses liquid chromatography/mass spectrometry to accurately measure free estradiol, the portion of estradiol that is not bound by SHBG.
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 (J 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.
