A PdG test is a urine-based hormone test that measures the amount of Pregnanediol Glucuronide (PdG) present in urine to help confirm ovulation and understand PdG levels during the implantation window. PdG is the urine metabolite of the hormone progesterone, which is produced by the ovary after ovulation. The test is non-invasive and can be done multiple days in a row, making it easier to confirm successful ovulation. PdG tests can help confirm that ovulation has occurred and monitor PdG levels after ovulation, during the implantation window. The test is available in strips and can be used at home. The Proov Confirm PdG test is the first and only FDA-cleared at-home test to confirm successful ovulation. The test is clinically proven and has been shown to be 99% accurate in lab studies. By tracking PdG levels, couples can save time, money, and heartache by identifying problems with ovulation early on.
