Special instructions

Please take your sample as soon as possible after waking. Your result could be affected by corticosteroid medication (e.g. prednisolone). Ask your doctor whether you should stop before testing. Do not take biotin supplements for 2 days prior to this test. If you are taking prescribed biotin you should discuss this with your doctor. Avoid taking a finger-prick sample from a finger used to handle hormone-gels or hormone-pessaries in the past 4 weeks.
Testosterone is a hormone that causes male characteristics. For men, it regulates the sex drive and controls bone mass, fat distribution, muscle mass, strength and the production of red blood cells and sperm. Heavy alcohol use, liver disease and using steroids can cause a decrease in testosterone levels. Women taking oestrogen therapy, however, may have increased testosterone levels.

Cortisol is a steroid hormone, produced by the adrenal gland. It's vital for survival as it's involved in various important functions such as immunity, regulating blood pressure and releasing insulin for blood sugar maintenance. Cortisol has been termed 'the stress hormone' because it's also secreted in higher levels during the body's 'fight or flight' response to stress, and is responsible for several stress-related changes in the body. 

Raised cortisol can inhibit the production of testosterone.

Extended upper limit. Many testosterone tests will not measure testosterone levels above 52 nmol/L Our test will measure values up to 520 nmol/L. This is especially useful for men who are taking testosterone replacement therapy (TRT) or anabolic steroids and who expect to have supranormal levels of testosterone.
