ZRT Estrogen Essential Profile

This metabolites profile (12 tests) zeroes in on estrogens only. This is a streamlined assessment of levels of estrone (E1), estradiol (E2) and estriol (E3), as well as how your body is processing and breaking down those hormones. For a more comprehensive test, see our Estrogen Elite Profile (estrogens plus other metabolites).

Testing hormone metabolites give us deeper understanding of the hormone activity in our bodies. Not only can we see how much of each hormone is being produced, but also how the body is processing each of them. Hormone related cancers and other diseases have been linked with excess build up of certain metabolites. This testing can therefore show possible increased risk. For example, a build up of 4-hydroxy estrogen has been linked with breast cancer and other hormone-related cancers.

You may want to test hormone metabolites if you:

  • Have a family history of hormone-dependent cancers, including breast or prostate cancer.
  • Noticing symptoms of hormonal imbalance such as weight gain and insomnia.
  • Showing symptoms of polycystic ovary syndrome (PCOS) such as acne and excess facial hair.
  • Are considering hormone replacement therapy due to menopause.

Dried urine is the most effective way to measure the presence of metabolites in, and being eliminated from, the body. Our easy to use, at home kits make testing accessible and convenient.
