Testosterone Test - Self-Collect and Post
This home testosterone test is a blood test to check the total amount of testosterone hormone in your bloodstream.
This testosterone test can be done at any time of the day, but it is best done between 8 and 11 am. This is because testosterone levels change during the course of the day and are highest in the morning.
The testosterone home testing kit contains all you need to take the blood sample and send it back to us. The testosterone blood sample is taken by pricking your finger with a small sharp lancet, the same small needles that are used by diabetics when they are checking their blood sugar. Please watch this video showing how this is done, before trying to collect the sample. Only a small amount of blood is needed.
Check that your address details are correct at the time of ordering the test. A testosterone self-collection pack containing clear instructions and testing equipment will then be posted to you.
You will post the sample you have collected in the postage-paid plastic envelope that is provided.
Please note that home tests are for personal use only. We cannot provide assurance to an outside agency that the test belongs to a particular individual. Assurance can only be provided when doing the test at Patient Reception in London when accompanied by a photo ID of the person being tested.
Results take: up to 2 working days *. They include a doctor's explanation of the meaning of the results.
Results will be emailed to you within 2 days* of receiving the sample.
* Indicative timings only. Actual result may be earlier or slightly later.
