Frequently asked questions

How accurate is an at-home testosterone test compared to a clinic test?

Some research suggests there is some variability between home testosterone test kits. However, the biggest variability was found in female testosterone test kits. To make sure our test kits have a high level of accuracy, they:

  • require a blood sample rather than saliva
  • are analysed by a UK-based accredited laboratory (TDL)
  • should be used first thing in the morning when testosterone levels are known to be at their highest

When should I take my testosterone test?

You should collect your sample for the home testosterone test first thing in the morning or as soon as you wake up and before you eat, as this is when testosterone levels are at their highest.

Can I use this test if I'm on TRT (testosterone replacement therapy)?

Yes, you can take the home testosterone test if you are on testosterone replacement therapy because it can help you monitor your levels during your treatment.

How often should I test my testosterone?

Once you have started testosterone replacement therapy, you will have a blood test after 3 and 6 months of treatment, and then once a year to make sure your levels are within a safe and normal range.

What's the difference between total and free testosterone?

Total testosterone measures the amount of testosterone in your blood, including any of the hormone that is and is not attached to proteins, while free testosterone only measures the active forms that are not bound to proteins.

Can women use this test?

No, but you can request a home testosterone test for women from Asda Online Doctor. The normal levels of testosterone for women are different, so it is important that you request the right test.
