The Biotime E2 Rapid Quantitative Test provides a fast and accurate method for measuring Estradiol (E2), the primary female sex hormone, in human serum. Estradiol plays a critical role in regulating the estrous and menstrual cycles, developing female secondary sexual characteristics, and maintaining reproductive tissues.

This test is ideal for monitoring menstrual irregularities, evaluating reproductive health, assessing fertility, and supporting the diagnosis of abnormal pregnancies, including twin or multiple pregnancies and gestational diabetes. The test is designed for ease of use with low sample volumes and requires no pre-dilution, making it suitable for laboratories, outpatient clinics, gynecology departments, endocrinology, and reproductive centers.
