How Much Do Private Blood Tests Cost in London?

A private blood test in London typically costs between £33.75 for a single marker and £420 for a comprehensive screening panel. At Medical Express Clinic, individual tests start from £33.75 and our four curated packages run from £124 to £420, with most results back within 24 hours.

Below is a plain breakdown of what you actually pay for, what changes the price, and how to avoid paying for tests you do not need.

What affects the price of a blood test?

• Number of markers. A single test is cheaper than a panel. Packages bundle related markers at a lower price per test.
• Specialist analysis. Genetic and niche tests, such as an Ehlers-Danlos NGS panel, cost more because of the laboratory work involved.
• Turnaround. Same-day or urgent results can carry a premium over standard reporting.
• Doctor input. Package prices include clinician review. Some single walk-in tests are priced for the test alone.

Package or individual test: which is better value?

For a general health check, a package such as the Gold package is usually better value than buying each marker separately. If you have one specific concern, for example thyroid function or female hormones, a single test keeps the cost down.

If you are not sure, our GMC-registered doctors can tell you which tests are worth doing before you pay, so you are not spending on markers that will not change anything.

Do you need a GP referral?

No. You can walk in or book online and choose your own tests at our Harley Street clinic, with same-day appointments available seven days a week.
