Day 21 Ovulation Progesterone Blood Test

About this test

Why take this test?

  • you are planning a family and want to check that you are ovulating normally
  • you are struggling to conceive and you want to check that you are ovulating as part of your fertility investigations
  • you've been advised to check your progesterone levels by a doctor 

For women planning a pregnancy, healthy levels of progesterone are absolutely essential. A progesterone test performed 7 days before your next period is due can identify whether ovulation has occurred. Progesterone is produced by the corpus luteum and adrenal glands. Together with oestrogen it helps to prepare the body to conceive. This test is an essential first step in investigating infertility. 

It is important to take this test 7 days before your next period is due. If you don't have a regular cycle then aim to take the test on the 21st day after the start of your last period. 

If you are ordering this test in conjunction with other tests and wish to take your progesterone test on a different day in your cycle you will need to place two separate orders to receive two separate test kits. 

Who is this test for?

This test is ideal for anyone wishing to establish the level of progesterone in their blood. It is especially useful for women planning a pregnancy or who have been trying to conceive without success.
