Progesterone

What can I expect from Progesterone?

Analysis of progesterone levels shows a large spike in the latter half of your cycle if successful ovulation has occurred. If you have regular periods it needs to be taken about 21 days after the first day of your last period. If you have an irregular cycle then test at 7 days before your next period.

A result of 30-65.5 nmol/L will confirm that you have ovulated.

Along with confirming ovulation if taken at about day 21 of your cycle there are many other reasons for checking your progesterone levels.

These include monitoring levels throughout pregnancy to check for risk of miscarriage, checking for polycystic ovarian syndrome.

This test works equally well as a finger prick home test as with a phlebotomy sample.
