Day 21 Ovulation Progesterone

What Does This Test Check?

This test checks progesterone around day 21 of the menstrual cycle to confirm that ovulation has actually taken place that month.

One test sits on this page, the Medichecks Ovulation Progesterone Blood Test at £39. With no second provider or price to compare, the choice is about timing your sample and wanting this specific fertility check.

A day 21 progesterone result may indicate whether ovulation occurred, but timing matters and one cycle does not tell the whole story, so the result should be discussed with a GP.
