Testosterone is a steroid hormone (an androgen) made in the testicles and in the adrenal glands. Testosterone has a variety of functions in men and is produced in high amounts in both males and females during puberty. Total testosterone levels can be tested using our home test kit. If your level is low, a repeat test is recommended after 4 weeks and you would need to see your GP or specialist to discuss starting treatment. If you have low testosterone and are already prescribed treatment and have regular check ups, you can order repeat treatment online.

About testosterone level testing and treatment

Who can get testing or treatment online?

You can get tested if you’re a male over the age of 18.

You can get treatment online if:

  • You’re aged 18 to 65
  • You have had 2 blood tests 4 weeks apart by your GP or specialist which have confirmed low testosterone
  • You have testosterone deficiency and you are currently being treated for it by your specialist and are up to date with check ups
  • You don’t have current or past health conditions that make testosterone treatment unsafe

How the test works

The test used to measure testosterone levels is a blood test. It is a convenient way to test your total testosterone levels without having to see a doctor:

  • Your kit will contain 3 lances and a collection tube
  • You will provide a sample of blood from your finger
  • The sample will be used to test your testosterone levels

Your results will be provided to you via your account. They should be ready within 2–3 days of the laboratory receiving your sample.

Levels of testosterone can vary a lot during the day and with meals. It is important that your blood sample is taken early in the morning (between 7am and 11am) and that you are fasting (this means that you should not eat or drink anything, except water, from 11pm the night before). If you have diabetes or have been told not to fast please chat to your GP or online doctor before taking the test.

It is also important that you don’t take the sample if you are feeling unwell as this can also lower your testosterone level.
