Progesterone check

Our progesterone check is a finger-prick blood test kit which can be done at home and then sent to our accredited lab for analysis. It’s a useful blood test for women who are planning to conceive and who want to check whether they have ovulated.

Progesterone levels change during the menstrual cycle and rise following ovulation. This test kit is, therefore, a reliable way to establish whether or not you have ovulated, quickly and affordably.

In order to achieve accurate results from this progesterone blood test, it’s important that you take it on day 21 of your menstrual period (or 7 days before the start of your next period).

Why check your progesterone?

  • You’re about to start trying to conceive
  • You’re trying to conceive already and it’s taking longer than you expected

Benefits of progesterone testing

By testing for progesterone in the blood on day 21, you clearly identify whether or not you have ovulated.

For those about to try and conceive, it’s reassuring to understand your cycle is as expected. For those, however, who are already trying and for whom it may be taking longer than expected, this could be a way to rule out ovulation problems.

Our progesterone check is a simple finger prick test carried out at home. You then simply send your sample to our lab and just a couple of days later, you’ll have your results on a digital dashboard designed to be easy to understand and which enables you to track your levels over time.

What our customers say

As a working mum, I often find myself training ‘tired’ as the demands of day-to-day life take their toll.  Forth has enabled me to gain a valuable insight into what is happening ‘under the surface’, so I  can adapt my training and lifestyle.

Kate Allan

I ran my first marathon in 2014 which left me feeling exhausted and constantly unwell. What I didn’t know then was that my iron and vitamin D levels were incredibly low.  By using Forth to test key biomarkers has put me in control of the areas I need to improve.

Jude Peck, 42

I'd put off getting regular blood tests before because of the long-winded process of a GP visit. Forth has changed all that. The process is very quick and very easy, with thorough, well-explained results delivered to your inbox within days.

Alice Hector

Forth really helped me understand issues that I was having, which in the end turned out to be problems with iron absorption. Without their test I would never have known this. I now have the knowledge I need to improve.

Sean Conway

I enlisted the help of Forth to help me get to the bottom of my current health concerns. The test was really easy to and my results were available within day. Using Forth has helped me take the action needed to get my hormones back on track.

Holly Rush, 39

Taking the test is simple just make sure you follow all the instructions so you follow the correct procedures. The customer service is second to none and the results are easy to understand and follow.

Matthew Bottrill

I was keen to use Forth’s service to help monitor my haematological markers in particular since I've had problems in the past and by the time they are picked up by the GP I'm normally feeling unwell.  The test was quick and easy to do and results were back very quickly. The results are also incredibly accurate, being almost identical to those from tests done by my GP the same day.

Alice Lethbridge

I suffer from a hereditary condition which causes my body to store too much iron.  My biggest issue before using Forth was getting an appointment with my GP.  Now using Forth I can track my iron quickly and easily and take action before levels start to affect my health

Mark Threfall, 29

As a former Olympic cyclist I always wanted to look after my health. This has never changed to this day but become a lot easier via Forth, it’s the only way to really understand your own body.
