Positively Pregnant translates cycle day and cycle length research into individualized pregnancy test sensitivity estimates, according to Alexandra C. Sundermann, MD, PhD.

Positively Pregnant, built on PRESTO data, gives patients day-specific, evidence-based estimates of home pregnancy test accuracy by cycle timing, as Alexandra C. Sundermann, MD, PhD, explains in this video.

A large preconception cohort study found that nearly 41% of pregnancy planners tested more than 4 days before their expected period, a pattern associated with a fivefold higher risk of false-negative results and threefold higher detection of very early pregnancy losses.

Very early home pregnancy testing modestly advances detection but substantially increases false negatives and detection of very early pregnancy losses, according to a recent study.

In a large preconception cohort, more than 40% of pregnancy planners reported very early home pregnancy testing, which was associated with higher risks of false-negative results and detection of very early pregnancy losses.
