Testosterone Test - Self-Collect and Post

Testosterone Test - Self-Collect and Post



  Results take: up to 2 working days

morning-sample  This test is ideally done between 8 and 11 am. This is because testosterone levels change during the course of the day and are highest at this time.

  This home testosterone test is a blood test to check the total amount of testosterone hormone in your bloodstream.

  The 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 but some samples may be rejected by the laboratory because there is not enough.

Please mention if you have any medical problems or are taking any medications or supplements as these may affect the result.

Check that your address details are correct at the time of ordering the test. A self-collection pack containing clear instructions and testing equipment will then be posted to you. 

liver-function-blood-test  Sometime combined with a liver function blood test to check for any damage to the liver if taking testosterone supplements.

  You will post the sample you have collected in the postage-paid plastic envelope that is provided.

  Results will be emailed to you within 2 days of receiving the sample.

  • tiredness
  • low mood, anxiety or irritability

What if I have an potentially abnormal testosterone level?

If you have given a morning blood sample (between 8 and 11 am) and your result is outside the normal range, then you should follow up with your own doctor as further testing will be required.
