GETTING A PRIVATE BLOOD TEST IN COCKFOSTERS

Everything you need to know about the costs, walk-in clinic options and what to expect from your blood test.

Many people think a blood test clinic has to be in a hospital or a big medical centre. Ours is on the High Street in Cockfosters, inside Surgicare Aesthetics, on the corner with Leys Gardens. You can book an appointment in minutes or walk in, and no GP referral is needed. Many results are available the same day.

You're probably wondering what it costs, how to find the entrance and how quickly your results will land. This page covers:

  • The £35 clinic charge and what the tests cost on top
  • Where the clinic is, when it is open and how to walk in or book
  • The questions we are asked most

If you already know which test you need, book your Cockfosters appointment and we will see you on the High Street.

WHY PEOPLE CHOOSE ONE DAY TESTS FOR BLOOD TESTS IN COCKFOSTERS

You want results you can rely on, and you want to understand them. So here is how we handle both. Our tests are comparable to the ones you would get through your GP, and they are processed in fully regulated diagnostic laboratories. All of the biomarker guidance that comes with your results is written by our in-house UK GPs, each with years of clinical experience.

On that same note, every test we run is subject to robust external quality assessment. Our laboratory tests over 100,000 biomarkers every month. If you prefer to speak to a human before you book, call us on 0127 309 2844 and we will talk you through how it works.

For anyone who likes to see the credentials, here they are.

  • CQC - Our pathology laboratory and phlebotomy clinics are CQC registered. Our parent company, Sussex Pathology Limited, holds certificate number 1-14470761199.
  • UKAS - Our laboratory is accredited as Medical Laboratory No. 29041 to the current ISO 15189:2022 standard.
  • Home kits - Our home test kits are MHRA/CE certified.

BLOOD TESTS AVAILABLE AT OUR COCKFOSTERS CLINIC

Our fully equipped Cockfosters clinic covers routine and specialist testing, with over 300 biomarkers to choose from. You can test a single marker, such as calcium or oestradiol, or order one of our comprehensive panels, some of which cover more than 50 biomarkers. You can also pick by symptom, or check a body function such as liver or kidney function.

Ready-made panels people often go for include the Full Blood Count, the Diabetes (HbA1c) Test, the Cholesterol Test and our popular Essential All Systems Blood Test. The most popular test in the whole range is the Ultimate Performance Test, with 59 biomarkers. The largest is the Ultimate Longevity Test at 74.

Having said that, not every test comes from a finger-prick. Some need a venous draw, which is one of the reasons people come to the clinic rather than testing at home. Here is a selection of other tests you can have taken at Cockfosters, with biomarker counts and usual turnaround.

HOW IT WORKS

The process is simple, whether you book ahead or drop in.

  1. Choose a blood test - Pick a single biomarker, a comprehensive panel, or a test matched to a symptom or body function. The Quick Finder helps if you are unsure.
  2. Choose a time, or just turn up - Book your appointment online in minutes, or walk in. The clinic is open Monday to Friday, 8 am to 2 pm. The £35 clinic charge applies to both and covers sample collection for all your tests on the day.
  3. Find the entrance - The clinic is at 26 Heddon Court Parade, Cockfosters, Barnet, EN4 0DB (view map). Some maps and phones send people to the wrong address, so here is the simple version: we are on the High Street where the shops are, on the corner with Leys Gardens, not inside Heddon Court Estate. Come in through the Surgicare Aesthetics entrance and you will find us inside. A qualified venepuncture nurse takes your sample from a vein, or by finger-prick where suitable if you prefer it or have difficult veins. Children aged 5 to 16 can be tested with a GP private referral letter (details here).
  4. Receive your results - Your results arrive by email as a secure, password-protected PDF, usually the same day your sample reaches our lab or the next day. Some specialist tests take a little longer, so get in touch first if your results are time-sensitive. You also get complimentary access to the Health Dashboard, where you can see your results as graphs, check them against reference ranges and track them over time.

BOOKING YOUR BLOOD TEST IN COCKFOSTERS

Go to our Cockfosters clinic page, pick a date and time, and enter your phone number to confirm. It takes minutes. If you would rather not plan ahead, drop in Monday to Friday between 8 am and 2 pm.

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 test regularly, a subscription gives you discounts on future tests, at a frequency of your choice, and you can pause or restart whenever you like.

If you need a custom panel, or you are not sure what you need, call us on 0127 309 2844 or email hello@onedaytests.com. We run our own laboratory, so we can build any panel you like.

FREQUENTLY ASKED QUESTIONS

Here are some of the most frequently asked questions about our clinic.

Can I walk in at Cockfosters without booking?

Yes. The Cockfosters clinic takes walk-ins as well as booked appointments, Monday to Friday, 8 am to 2 pm. The £35 clinic charge is the same either way. If another part of London is handier, our other London clinics are open to walk-ins too.

Can I book my Cockfosters appointment online?

Yes. Choose your tests on our website, then pick a date and time on the Cockfosters clinic page and confirm with your phone number. Booking takes minutes. No GP referral is needed, with one exception: children aged 5 to 16 need a GP private referral letter.

How do I find the clinic entrance?

We are at 26 Heddon Court Parade, on the High Street where the shops are, on the corner with Leys Gardens. The clinic is inside Surgicare Aesthetics, so use the Surgicare entrance. Some maps and phones point to Heddon Court Estate instead, which is the wrong spot. The photos on the clinic page show the entrance.

How quickly can I get tested and get my results?

You can book a same-day appointment or drop in. Most results arrive by email the same day your sample reaches our lab, or the next day, as a secure, password-protected PDF. Some specialist tests take a little longer, so get in touch if your results are time-sensitive. Our clinics across the UK work the same way, so if you are nearer Birmingham, for example, you can book there instead.
