99% accurate at-home ovulation prediction and confirmation via LH and PdG urine tests

Proov's Predict & Confirm kit includes 15 LH (luteinizing hormone) tests to identify your two most fertile days and 5 FDA-cleared PdG (pregnanediol glucuronide, a progesterone marker) tests to confirm successful ovulation during the implantation window. The kit generates a proprietary Ovulation Score; studies show sustained elevated PdG during days 7–10 after peak fertility can increase pregnancy…

Evidence

4/5

LH surge detection for ovulation prediction is supported by observational studies and clinical validation showing 90%+ sensitivity and specificity when used correctly. Progesterone metabolite tests for post-ovulation confirmation are similarly validated. The evidence is robust for the intended use—timing intercourse or confirming ovulation occurred—though accuracy depends on consistent testing protocol and individual cycle variability.

Mechanism

Ovulation prediction kits detect luteinizing hormone (LH) surge in urine, which typically precedes ovulation by 24–36 hours. Confirmation tests measure progesterone metabolites (pregnanediol glucuronide) in urine after ovulation has occurred, confirming the luteal phase. Both rely on well-established endocrine physiology.
