Why do you need a hormone blood test?

All Harmon members are required to undergo hormone blood tests both, before they start any treatment, to allow Harmon Doctors to provide them a personalised treatment regime, tailored precisely to their body's specific hormonal needs, and once they’ve started hormone replacement therapy, to monitor their treatment. In particular:

1. Importance of the hormone blood test before starting any hormone replacement therapy:

Evaluating your hormones, such as Estrogen, Progesterone, Testosterone and DHEA before any therapy has been commenced, is helpful in understanding which hormones are driving your symptoms. This correlation between the hormone levels in your bloodstream and your symptoms facilitates the selection of the best treatment regime for you.

2. Importance of the hormone blood test once you’ve started hormone replacement therapy:

Once you’re on Bioidentical Hormone Replacement Therapy (BHRT), the blood test is an essential tool that allows your Doctor to know that your regime is working effectively and that the amount of hormones in your body is not higher or lower than what is physiologically appropriate.

Important note:

  • If you’re a perimenopausal woman: Please note that the fluctuations of female reproductive hormones in a single day are significant only in the follicular phase but not during the luteal phase*. For this reason, we request our members, who are still experiencing menstrual cycles, to have their blood test done after day 21 of their cycle (luteal phase).

  • If you’re a menopausal woman: Please note that, as the British Menopause Society and NICE guidelines attest, hormone blood tests are rarely required to diagnose menopause in women aged over 45, as menopause marks the date 12 months after your last period. However, hormone blood tests are still an essential tool that enables Doctors to deliver precise, personalised care when a person is struggling with an age-related hormonal imbalance.
