How to book a blood test at one of our London clinics

Booking a blood test at one of our London clinics is designed to be a seamless and accommodating process, ensuring that everyone can access the necessary health checks with ease and convenience:

  • Choose Your Blood Test: From comprehensive health overviews to specific organ checks like liver or kidney, our wide selection of blood tests covers every need – for routine health tracking, diagnostics, or improvement.

  • Schedule Your Appointment: Flexible scheduling and short waits. A quick, easy blood draw by a professional phlebotomist, using your preferred method.

  • Receive Your Results: We prioritise not only the prompt delivery of your test results, which you'll receive via a secure, password-protected email typically within the same day or the next day after the sample arrives at our lab, but also clarity and understanding.

How does the full service work?

At our London clinics, we welcome anyone seeking professional assistance with blood sample collection, those in need of rapid test results, or patients whose tests require venous blood collection as per medical recommendations. Our process is designed for your convenience and efficiency:

Booking and walk-ins

You have the flexibility to schedule your appointment at a time that suits you best or to take advantage of our walk-in service. We always aim to accommodate same-day appointments, ensuring you can have your blood drawn by a professional venipuncture nurse without unnecessary delays.

Blood collection techniques to suit you

Understanding that some individuals may feel apprehensive about traditional blood draw methods or face challenges with venous access, we offer an alternative finger-prick technique. This option is designed to make the blood collection process as comfortable and stress-free as possible.

Comprehensive test options

With over 300 biomarkers available and an array of pre-designed test panels such as Full Blood Count, Diabetes, Cholesterol, and our comprehensive "Essential All Systems Blood Test," you're provided with a wide selection to meet your health monitoring needs. Our full test menu is designed to cater to a variety of health concerns and goals.

Home testing solutions

For those who prefer the convenience of not visiting the clinic, we offer home sample collection kits and the option for home visits from an experienced medical professional. These alternatives provide flexibility and comfort, allowing you to choose the best fit for your lifestyle and needs.

Receiving results

Results are swiftly delivered via email in a secure, password-protected PDF, typically on the same day the lab receives your sample. You can share these results with your GP or another healthcare provider for consultation.

Additionally, you gain complimentary access to our Health Dashboard, a powerful tool for tracking health metrics over time. This feature helps you observe changes, understand biomarker levels, and make informed lifestyle adjustments based on your health data, empowering you to take control of your well-being.
