Hormone Replacement Therapy (HRT) Blood Test

Monitor your levels of oestradiol, progesterone, and FSH during hormone replacement therapy (HRT).

Hormone Replacement Therapy (HRT) Blood Test

Hormone Replacement Therapy (HRT) is a treatment used to alleviate symptoms associated with menopause by replenishing the body with hormones that are at lower levels during this period.

Why have a Hormone Replacement Therapy (HRT) Blood Test?

  • Optimising Treatment Dosage: Regular blood tests help determine if the dosage of hormones in the HRT regimen is appropriate for you. Adjustments may be needed based on hormone levels to ensure that the therapy effectively relieves menopausal symptoms while minimising potential risks.
  • Assessing Hormone Balance: Monitoring hormone levels allows healthcare providers to evaluate the balance between oestradiol and progesterone, essential for mimicking the hormonal fluctuations of a natural menstrual cycle in women who have not undergone a hysterectomy. This balance is crucial for preventing endometrial hyperplasia and reducing the risk of endometrial cancer.
  • Evaluating Treatment Response: Blood tests provide insight into how the body is responding to HRT. Changes in hormone levels can indicate whether the therapy is effectively managing menopausal symptoms, such as hot flashes, vaginal dryness, and mood swings.

Please note:

  • Results can take up to 2-3 working days from the sample being sent in the post.
  • Your results will include a doctor’s overview which should give you all the information you require. If you would like further information, we recommend you visit your GP.

What is the process?

  • Our experienced phlebotomist will uncover your right or left arm.
  • A tourniquet will be placed around your upper arm. A tourniquet makes it easier for a needle to be placed in your veins by swelling the veins.
  • Once the tourniquet is fitted, a small quantity of blood will be drawn into tubes, using a needle.
  • After the blood draw is completed, a plaster will be placed onto the site; this can be removed after a couple of hours.
  • We will then post your sample to our partner laboratory for analysis.
  • You will receive your results 2-3 working days after the sample has been sent onto the laboratory.

  • Loose Clothing – Our phlebotomist will require access to your arm. Please wear loose clothing to make accessing your arm easier and more comfortable.  

  • Medication – Please let our phlebotomist know if you are on blood thinners on the day of your blood draw.
