Testosterone Check 1 health indicators-in store/ home

The Testosterone Check is a single-marker blood test measuring total testosterone, the principal androgen affecting libido, muscle and bone, processed by London Medical Laboratory (LML), a UKAS-accredited ISO 15189 laboratory, and sold by Ways Pharmacy (UK).

Key facts

Who it is for

• Men with symptoms of low testosterone — low libido, fatigue, muscle weakness, low mood
• Men being assessed for hypogonadism, erectile dysfunction, or possible infertility
• People using testosterone supplements or therapy who need to monitor their level
• Anyone wanting a single, focused testosterone reading to discuss with a clinician

Not suitable for: a complete hormone work-up on its own (consider the Testosterone Plus or Male Hormone profiles); acutely unwell people who need urgent assessment; replacement for assessment by a doctor.

What is measured

• Total testosterone — the main male sex hormone, also present in lower amounts in women. It is important for libido, fertility, muscle and bone strength, and mental wellbeing. Levels are highest in the morning, which is why a morning sample is preferred.

How it works

1. Complete payment online and choose your option: an appointment at Holborn London, or an at-home self-collection kit posted to you.
2. Plan a morning sample. Testosterone is highest between about 7am and 10am, so collect or attend in this window where possible.
3. For in-store, attend Ways Pharmacy, 77 Southampton Row, London WC1B 4ET, where a trained operator takes a blood sample. For at-home, follow the kit instructions to collect a finger-prick sample and return it in the prepaid packaging.
4. Your sample is sent to London Medical Laboratory for analysis.
5. You receive a written report with your result against the reference range, typically within 3–5 working days. A pharmacist can talk you through it and recommend GP follow-up where appropriate.

Frequently asked questions

What time of day should I take a testosterone test?

Testosterone levels are highest in the morning, so the sample is ideally taken between 7am and 10am. A morning sample gives the most reliable reading; if a result is borderline, the pharmacist may suggest repeating it in the morning.

How long do results take?

Results are typically returned 3 to 5 working days after London Medical Laboratory receives your sample. You will receive a written report showing your level against the reference range.

Is the laboratory accredited?

Yes. Samples are processed by London Medical Laboratory (LML), a UKAS-accredited laboratory operating to ISO 15189, the international standard for medical testing laboratories.

What is the difference between this and the Testosterone Plus Profile?

This test measures total testosterone only. The Testosterone Plus Profile adds SHBG, albumin and a free testosterone calculation, giving a fuller picture of how much testosterone is biologically available. Ask the pharmacist if you are unsure which is right for you.

What if my testosterone is low?

A low result does not diagnose a condition on its own. The pharmacist will explain what your level means and recommend appropriate follow-up, which may include a repeat morning sample or referral to your GP. Reference ranges are provided with your report.

When to seek further advice

This test does not diagnose a condition. Reference ranges are provided with your report; discuss your results with a clinician, and if a result is abnormal, follow it up with your GP. Seek prompt medical advice if you feel acutely unwell.

This is a private health screening service. Results are interpretive and do not replace clinical diagnosis by a GP or specialist. Abnormal results should be followed up with your GP.
