You can book or walk in, no GP referral is needed, and many results are ready the same day.

Come and visit us at the South Kensington clinic for quick turnaround test results.
The clinic is a one minute walk from Gloucester Road Tube station, so it fits easily into a normal day. Once you are in, our experienced medical team keeps the visit comfortable and stress-free, and we pride ourselves on a rapid turnaround, with many results available the same day.
Having said that, you will want to know the tests themselves hold up. They match the ones your GP would order, and they are processed in the same fully regulated diagnostic laboratories. Every biomarker explanation is prepared by our in-house UK GPs, each with years of clinical experience. If you are not sure what you need, email hello@onedaytests.com and chat to a human.
For anyone who likes to see the credentials, here they are.
Our modern, fully equipped South Kensington clinic covers routine and specialised testing, with over 300 biomarkers to choose from. You can test one marker, such as calcium or oestradiol, or order a comprehensive panel that tests many biomarkers at once, some with more than 50. You can also start from a symptom, or check a body function such as liver or kidney function.
So with the single tests covered, what about the ready-made panels? The ones people reach for most are the Full Blood Count, the Cholesterol Test and our popular Essential All Systems Blood Test. The most popular test in our whole range is the Ultimate Performance Test, with 59 biomarkers, and the largest is the Ultimate Longevity Test at 74.
Our phlebotomist takes the sample from a vein, or from a capillary if you prefer. Some tests are marked venous only, which is one reason to visit the clinic rather than test at home. Here is a selection of other tests available at South Kensington, with biomarker counts and usual turnaround.
ULTIMATE PERFORMANCE TESTThis is the most popular test in our range. An ultimate blood screen that reports on a huge panel of 59 different biomarkers, for a detailed overview of your body. Suitable for men and women of all ages. Includes a comprehensive review and report on your micronutrients and vitamins, thyroid, hormones, fertility, testosterone, organ functions, cholesterol, blood disorders, immunity, metabolism, stress, hydration, and much more. Get your full body systems health check from one of the UK’s largest and most trusted blood testing laboratories. |

The process is simple. Here is what a visit to South Kensington looks like.
Open our South Kensington clinic page, pick a date and time, and confirm with your phone number. If you would rather just drop in, walk in Monday to Friday between 8 am and 2.30 pm for same-day testing.
The £35 appointment and clinic charge covers sample collection for all the tests you have on the day. Blood tests are not included in that charge, so add the ones you want to your basket separately. If you plan to test regularly, a subscription gives you discounts on future tests, at a frequency of your choice, with the option to pause or restart.
If you need a custom panel, or you are not sure what you need, email hello@onedaytests.com and chat to a human. We run our own laboratory and can build any panel you like.

You pay the £35 clinic charge plus the price of the tests you choose. The charge covers the phlebotomist taking your sample for all your tests on the day. Prices are shown on each test page. As a guide, here are three examples.
Yes. If you would rather not come in, we offer a home sample collection kit, which is UK MHRA approved. However tests marked venous only need a sample taken from a vein at the clinic, and the clinic is the better choice if you need your results quickly.
