Oestradiol Blood Test

Oestradiol is a hormone produced in the ovaries and (to a far lesser extent) the testes. It regulates the female reproductive system, the growth of breast tissue and bone thickness. The Oestradiol Blood Test monitors the level of the hormone in your blood.


Why test Oestradiol?

Common reasons for this blood test are:

  • To help investigate the potential causes of abnormal periods, heavy bleeding or menopause symptoms
  • You take testosterone and want to monitor the level of female hormones
  • You are biologically male and are concerned about the growth of breast tissue.

Your blood test

Our phlebotomy-trained professionals will take a blood sample from you. This sample will be analysed in the UK by our authorised partners, TDL. By booking this blood test, you agree for us to share your personal information with TDL in order to process your test. We’ll make sure you consent to this at your appointment too.

Frequently Asked Questions

No, we will send you the results and recommend that you share these with your GP or fertility provider.

It is not unusual for some bleeding to occur under the skin following your blood test and sometimes this can extend a little further around the puncture site.  If this causes you concern, check with your practice nurse. 

Sometimes we cannot get a blood sample from you. This can be for many reasons, such as not being hydrated enough, feeling cold or having another blood test recently. We will always offer you another appointment so we can try again.
