More about the methods of testing

Testing at a Clinic

GenderGP works with a large blood testing service with over 170 clinics around the UK – including the South West, Wales, Northern Ireland and Scotland.

Once you have identified your nearest clinic on this LIST place your order through GenderGP and you will receive an email with details of the Booking Centre at the Pathology Service. You can then call them to arrange an appointment at a convenient time.

As with all blood tests, there is a chance that the sample can fail, however, having your sample taken by a professional phlebotomist and processed on site, greatly reduces that risk.

Results will be returned to GenderGP within three working days.

Testing through your local health service

We can send a letter to your doctor to request that they arrange the tests for you. The benefits of this are that, unless local charges apply, it is free. Your doctor will be sent all the relevant information including what tests you require and how to return the results via our Confidential Information Transfer system. A link to this will also be provided.

You will also receive a copy of this letter for your records. Please note that we will contact you once we have received and reviewed your blood test results.


Important: Blood Test Contamination

Certain medications can contaminate blood tests, leading to inaccurate results.

Be careful when taking blood from an area of skin that has been in contact with gel or cream or spray to avoid hormone contaminating the blood test and getting an abnormally high result.

If using gel, creams, or sprays:

  • Apply to shoulders, upper arms or thighs
  • Use gloves to apply for 3 days leading up to the test
Please note that if the results are contaminated, we will be unable to review your treatment.
