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.

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.
- Practitioner review included. Every result explained in plain language: what is in range, what is borderline and what to do next.
- Joined-up care. Results can inform nutrition and lifestyle advice, a GP consultation by video, or a referral to your own 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.
- One team, wherever you live. Book with Omnia, give your sample near you, and keep the same team for your results and any follow-up. If you are in London, you can also visit our clinic in Chiswick.

Testing is carried out in partnership with Randox Clinical Laboratory Services, an ISO/IEC 15189 accredited laboratory (UKAS Lab ID 9329), and reviewed by an Omnia practitioner. 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 a results review, with no extra fee for testing outside London.
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.
