About the test

• Testosterone is produced in the testes in men and is traditionally considered to be the ‘male’ sex hormone. Whilst it is produced in much higher quantities in men, women also produce testosterone in the ovaries and normal testosterone levels are important for both men and women

• Testosterone is necessary to maintain mood, muscle mass, energy levels, libido and sexual function. It is also important for fertility in men. Lacking testosterone can lead to vague but pervasive symptoms, such as low mood and fatigue. More marked symptoms can include loss of muscle mass, loss of body hair, erectile dysfunction, changes in sleep, and the development of breast tissue in men

• Although testosterone levels do decline gradually with age, sharp declines in testosterone levels can occur due to a number of medical conditions and you may be at higher risk of this happening if you have had previous illness or injuries that have affected the testes

• Testosterone Blood Test reference ranges vary based on age, sex, population sample and numeric test result ranges. However, once you complete your tests, you will receive clear reference ranges for your Testosterone Blood Test

• The testosterone test should be taken in the morning, between 7am and 10am

• If you take biotin supplements, stop taking them 72 hours before the test

• If you are using gel testosterone replacement therapy, do not take the finger prick test from the hand you use to apply the gel
