This estrogen metabolism ratio test measures important estrogen breakdown products with one simple urine collection. How your body metabolizes and eliminates certain estrogens plays an important role in determining your breast cancer risk.

This test measures 2-hydroxyestrone and 16 alpha hydroxyestrone to provide a 2/16 ratio and illustrate the risk of developing estrogen-sensitive breast cancers.

• High 2-hydroxyestrone levels reduce your risk of breast cancer.
• High 16-a-hydroxyestrone levels increased your risk of breast cancer.
