How a visit works

A visit has five steps, from choosing a test to reading your result.

1. Choose your test

Search or browse the full catalogue of over 1,000 blood, urine and swab tests. Each test page shows its price, its turnaround and any preparation. Not sure which test you need? Start from the symptom or condition.

2. Walk in or book online

You can walk in at 117a Harley Street seven days a week without an appointment or a GP referral. Booking online guarantees your time. When you book online you pay sample collection £50, and the test fee at the clinic.

3. Have your sample taken

Your sample is taken in person by our nursing and phlebotomy team. The blood draw takes a few minutes, and one visit can cover several tests. If you walk in, you can choose your tests at reception when you arrive.

4. Your sample goes to the laboratory

Samples leave the clinic by laboratory courier every hour and reach a UKAS-accredited laboratory the same day, weekends included.

5. Get your results by email

Your report is emailed to you as soon as it is ready, whatever it shows. If you would like a doctor to explain it, add a doctor review for £75.

How fast results come back

Most routine blood tests report within 1 day of the sample reaching the laboratory, and samples get there on the day they are taken. Some tests report in as little as 6 hours. Specialist and genetic tests take longer, from several days to a few weeks.

Who takes your blood, and where

Every sample is collected in person inside our CQC-registered medical practice by our experienced nursing and phlebotomy team. The team perform thousands of venous draws every year, including for nervous or needle-phobic patients, children (by arrangement), oncology patients, and anyone who has been told they have deep, small or difficult veins.

Blood is drawn from a vein into full-volume laboratory tubes, labelled in front of you, and prepared for courier dispatch. Samples leave by courier every hour for The Doctors Laboratory (TDL) and our UKAS-accredited partner laboratories.
