Frequently Asked Questions
How much is a private blood test in London?
Single tests start from £35. Full profiles range from £59 to £499 depending on what is included. You only pay for what you need — no hidden fees and no GP consultation charge required.
Do I need a GP referral for a private blood test?
No referral is needed. You can book any test directly online or by phone and attend the same day. Your results are sent securely to you — not to your GP unless you request it.
How do I get a blood test privately?
Simply choose the test or profile that matches your concern, book online or call us on 020 77 240 540, and attend our Baker Street clinic at your chosen time. Same-day appointments are available and walk-ins are welcome subject to availability.
Where can I get a private blood test near me?
Marylebone Diagnostic Centre is located at 73 Baker Street, London W1U 6RD — 5 minutes from Baker Street tube station on the Bakerloo, Circle, Jubilee and Metropolitan lines. We serve patients from across London including Marylebone, Mayfair, Paddington, and the West End.
Are private blood tests better than NHS?
Private blood tests are not necessarily more accurate than NHS tests — both use accredited laboratories. The difference is speed and accessibility. With MDC you get same-day appointments, no referral needed, results in 24–42 hours, and the flexibility to choose exactly which tests you want.
Are private blood tests worth it?
For many people, yes. If you are waiting weeks for an NHS appointment, have a specific concern you want answered quickly, or want to test markers your GP has not recommended, private testing gives you direct access and faster answers. Tests start from £35.
How quickly will I receive my results?
Most results are ready within 24 to 42 hours. Some specialist panels may take slightly longer. You will be notified as soon as your report is available in your secure patient portal.
Does private health insurance cover blood tests?
This depends on your policy and provider. MDC is a registered provider with WPA and Helix insurances. We recommend checking with your insurer before booking. We accept all major credit cards and bank transfers for self-pay patients.
