What will your results tell you?

A breakdown of your estradiol levels and actionable follow-up steps

Estradiol is the most potent form of estrogen produced by the body. Good estradiol levels contribute to a healthy reproductive system and strong bones and joints. Estradiol imbalances, however, can cause problems: Too much estradiol may lead to depression, acne, and decreased sex drive, while low estradiol can raise the risk of mood swings or osteoporosis. True Marker’s at-home estrogen test is a safe and effective way to monitor your estradiol levels. 

Our estradiol test is taken in the privacy of your home. Once you send in your test sample, we’ll deliver the results back in 3 days. Our at-home estradiol test also includes a full report of your results in a PDF to share with your doctor.
