How to book a blood test at our Croydon blood tests clinic

The process is simple:

1. Choose a blood test in Croydon

Pick a test for a single biomarker, for example, Homocysteine or Estrogen, or order a comprehensive panel (some panels have over 50 biomarkers!). You can also check a particular body function, such as liver or kidney function or dive deep with our symptoms search tool.

2. Choose a clinic appointment time

Book an appointment at our Croydon blood test clinic. Our skilled phlebotomist nurse will take your blood from the vein (or help you with a capillary sample, if you prefer). Choose this option if you would like help getting the sample, your chosen tests are recommended as ‘venous only’, or if you need the results in a hurry. Venous method is always quicker.

3. Receive your results

Your results will arrive via email, in a password-protected, secure PDF file and will usually be available the same day the sample reaches our lab. Some of the biomarkers may take a little longer as they require longer processing time.

How does it work?

Visit our clinics for quick and convenient assistance with your blood samples.

Book an appointment or walk in at your convenience. Same-day appointments are available, allowing our professional venipuncture nurse to efficiently take your blood.

We offer both vein and finger-prick techniques to accommodate your preferences and address difficult veins if needed.

No GP referral is necessary, and results are typically delivered the same day.

Receiving results
