Essential Estrogens™ is a targeted urinary hormone test designed to evaluate estrogen metabolism. It is used for initial estrogen assessments and follow-up testing to monitor response to therapies. This test uses an FMV collection. It can also be ordered as a 24-hour collection. NOTE: When ordering, please add a "Note to Rupa" indicating whether or not the patient is using HRT. This information is required to place the order with Genova.
