What a TRT blood test checks
Testosterone replacement therapy, or TRT, changes more than your testosterone level. Doctors who prescribe it usually check a set of markers before treatment starts and at regular points afterwards. Our laboratory partner Randox analyses every sample.
- Total and free testosterone, with SHBG, to show how much testosterone your body can use.
- Oestradiol, which can rise on testosterone.
- Haematocrit and a full blood count, because testosterone can thicken the blood.
- PSA, a prostate marker checked before and during treatment.
- Cholesterol, liver and thyroid markers, for a wider picture of your health.
We do not prescribe testosterone. If you are on TRT through a clinic or your GP, follow the test timing they give you and share your results report with them.

Who books a TRT blood test
- You are thinking about TRT and want a baseline first.
- You are on TRT and need regular monitoring.
- You have low energy, low mood or low libido and want your testosterone checked.
- You train hard and want to understand your hormone levels.
Preparing for your test
Testosterone is highest in the morning, so book an appointment before 11am if you can. Panels that include cholesterol need 8 to 12 hours of fasting, water only, and we confirm this when you book. A low result is usually rechecked with a second morning sample before any conclusion is drawn. We see clients by appointment only.
Omnia Health Checks
Eight health checks, one clear path.
From a quick essentials check to our most comprehensive assessment. Open any check to see every biomarker, who it suits and how your appointment works.
Test finder
Not sure which test is right for you?
Answer three short questions and we will suggest the panel that fits what you want to understand, with an alternative if you would like more or less detail.
Your practitioner confirms the choice with you before any sample is taken, so you never pay for markers you do not need.

Before you come in. Some tests, such as glucose, triglycerides and some cholesterol and iron markers, are best taken after 8 to 12 hours without food, with water allowed.

Why Omnia
A clinic, not a testing kiosk.
The value of a blood test is in what happens after the numbers arrive. At Omnia, your results become a plan.
- A clear results report. Every marker set out in plain language: what is in range, what is borderline and what is worth rechecking.
- Joined-up care. Results can inform acupuncture, Ayurveda, physiotherapy or nutrition care here, or a referral to your GP.
- Honest about what testing is. A result outside the range is a prompt, not a diagnosis. If anything needs a doctor, we say so and give you the report.
- Close to Turnham Green station. District line, with Piccadilly line trains early in the morning and late in the evening only. Limited parking is available on request when booking.

Testing is carried out in partnership with Randox Clinical Laboratory Services, an ISO/IEC 15189 accredited laboratory (UKAS Lab ID 9329). Where a panel has female and male versions, the difference is mainly the hormone and tumour marker selection. All prices include the blood draw, laboratory analysis and your results report. GP feedback and GP consultations are available on request, at an extra cost.
These tests do not replace care from your GP. If you have worsening symptoms, unexplained weight loss, bleeding or severe pain, please see a doctor first.
