Timing of test:

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.

  • Lancets x 3
  • Blood collection vial
  • Alcohol swabs x 2
  • Cleaning wipes x 2
  • Spot plasters x 2
  • Instruction sheet
  • Postage-paid envelope

The postal testosterone test 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 test kit containing clear instructions and testing equipment will then be posted to you by Royal Mail.

important-information 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 * once they reach the laboratory. Results include a doctor's explanation of the meaning of the results.

Results are emailed.

* Indicative timings only. Actual result may be earlier or slightly later.
