I recently visited for a blood test and had a really positive experience. The customer service and care were excellent, and I was very impressed with how kind and professional the staff were. It was quite difficult to find a vein, but the lady who took my blood was very skilled and managed to do it without causing me any pain or discomfort. I really appreciated her patience and care. Overall, I had a very good experience, and I would definitely choose to come back here again whenever I need another blood test. Thank you for your excellent service and care!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

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.
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.
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.
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.
No waiting lists. No GP referral. Results in 24–42 hours.
