About this test

For women planning a pregnancy, healthy levels of progesterone are absolutely essential. A progesterone test performed on day 21 of the menstual cycle can identify whether ovulation has occured. Progesterone  is produced from the corpus luteum and adrenal glands. Together with oestrogen, it works to prepare the body to conceive. This test is an essential first step in investigaing infertility. 

An increase in progesterone levels after ovulation can cause the uncomfortable symptoms associated with PMS.

Progesterone has other actions in the body including improved fat metabolism, increasing bone density, mood-elevation, and it can also act as a natural diuretic.

You may want this test to assess your progesterone level if you have irregular, heavy, absent or painful periods, are unable to conceive or menopausal.

Who is this test for?

This test is ideal for anyone wishing to establish the levels of progesterone in the blood. It is especially useful for women planning a pregnancy or who have been trying to conceive with no success.
