Estradiol Free, Equilibrium Dialysis, With Total Estradiol, HPLC/MS-MS (Endocrine Sciences)

This test measures the total amount of estradiol, a primary form of estrogen, and specifically identifies the free portion that is active and available for your body to use. It helps show whether hormone levels are balanced, which is particularly useful for evaluating fertility issues, puberty development, or estrogen levels in men. By distinguishing between bound and active hormones, this test helps rule out misleading results caused by proteins that carry hormones in the blood. However, it cannot diagnose the specific medical condition causing abnormal levels without a full medical evaluation.
