Testosterone Test
Total and free testosterone, SHBG, and what the numbers typically mean.
A testosterone test measures the level of testosterone in your blood. Private testosterone tests in the UK typically measure total testosterone, free testosterone and SHBG (sex hormone binding globulin) so you can see both the total amount and how much is biologically available.

Why it matters
- Low testosterone is associated with low energy, reduced libido, mood changes and loss of muscle mass.
- Levels follow a daily rhythm — most clinical labs recommend a morning sample (typically before 11am).
- Results should always be interpreted by a qualified clinician alongside your symptoms.
How testing works
- Choose a finger-prick home kit or a clinic venous draw from an accredited provider.
- Collect the sample in the morning, ideally fasted, and post or return to the lab.
- Results are typically returned in 2–5 working days with a clinician-reviewed report.

Frequently asked questions
What is a normal testosterone level for a man?
UK reference ranges for adult men typically sit around 8.6–29 nmol/L for total testosterone, but ranges vary by laboratory and age. Always interpret results against the range printed on your report and discuss with a clinician.
Do I need a doctor's referral?
No. Private testosterone tests in the UK are available direct-to-consumer from CQC-regulated providers, with clinician-reviewed reports included.
Finger-prick or venous blood draw?
Both are accepted by UKAS-accredited laboratories. Venous samples are generally preferred when accuracy is critical or when multiple hormones are tested together.
