Female Hormone Mapping Test

By Forth

This ground-breaking female hormone test predicts how your four key female hormones fluctuate over your entire menstrual cycle rather than just a single day.

Using the latest techniques in artificial intelligence, we combine blood analysis with medical expertise and mathematical modelling, to give you unparalleled scientific insight into your personal hormone health, with support and advice from Forth’s Chief Medical Officer and leading endocrinology expert, Dr Nicky Keay.

By combining medical grade laboratory blood analysis with clinical expertise and artificial intelligence, Female Hormone Mapping predicts how a woman’s four key hormones fluctuate throughout their entire cycle, which is entirely unique to you. It’s the next step in personalised female health intelligence.

This test is for women who have a natural menstrual cycle and are not on hormonal contraception or HRT.

You’ll get explanation, commentary and advice from Forth’s expert endocrinologist on:

  • Your unique curves which show how each of your four key hormones are predicted to fluctuate throughout your personal menstrual cycle
  • Identification of any potential problem areas 
  • Confirmation if ovulation has occurred
  • Ovarian response score indicating how well your hormone network is working
  • For women over forty, confirmation if they have entered the perimenopause
  • Increased understanding of the link between hormones fluctuations and your health & wellbeing
  • An evidence-based action plan to support your female hormone network

How it works:

  1. You will receive a kit that contains x2 tests, the first test should be taken on day 14 of your period and posted to our lab the same day. The second test should be taken on day 21 of your period and posted the same day*.
  2. When you take each test, you need to log how you feel on that day by answering a few questions on your Health Dashboard which you will gain access to when you set up your account. This is so we can correlate how you feel with your hormone fluctuations.
  3. Your full report will be sent to you within 2 working days of our lab receiving your day 21 blood sample.

*If your day 14 or 21 falls on a Friday, we recommend you collect your sample the day before. If your day 14 or 21 falls over the weekend, collect your sample on the following Monday and remember to post in a priority post box in time for that day’s collection.
