Why Is It Important?

Estradiol, Mass Spectrometry provides your physician with a quantitative measurement of your estradiol levels that can help determine conditions associated with increased levels of estradiol such as tumors in the ovaries or testes, hyperthyroidism, and cirrhosis. Lower levels of estradiol can indicate menopause, polycystic ovary syndrome (PCOS), compromised estrogen production, sexual dysfunction and low libido and more. Understanding your estradiol levels will help you and your doctor make the most informed decisions about your care.
