London Blood Tests works with over 10 UKAS-accredited partner laboratories and CQC-registered clinics, which gives them a solid edge in providing reliable testing.
This massive network also means you can secure competitive quotes without sacrificing accuracy.
Here, you have flexible sample collection choices. You can easily opt for an in-clinic visit or simply use an at-home testing kit. Most routine results are securely delivered through their online portal within two days.
If you need a bit of guidance, you can even schedule an optional interpretation and follow-up consultations with experienced General Medical Council (GMC) registered doctors.
Just keep in mind that the base test price doesn’t always cover everything. Also, the in-clinic draws or home visits incur extra collection and consultation fees.

Responsive Home Blood Testing Service
We used LBT to get private blood tests for my partner. A phlebotomist came to our house, took the blood and it was couriered to the lab. When there was a technical problem at the lab, LBT made sure to push them to obtain a result the next day which was great.

2. London Health Company (LHC) Laboratory
Website: https://londonhealthcompany.co.uk/
Address: Queen Mary Innovation Centre (QMB), Suite 7, Lab 1, 42 New Road, E1 2AX
Contact: 02080870017 | [email protected]
Hours: Laboratory: Mon to Fri 9:00 AM – 5:00 PM, Customer Support: Mon to Fri 10:00 AM – 6:00 PM
London Health Company has a direct-to-consumer approach that allows you to receive a complete finger-prick blood collection kit by post.
You can gather your sample at home and return it using prepaid packaging, completely skipping the need for a clinic appointment.
I actually spoke with a colleague who used their home kit, and she was surprised by how straightforward the whole process felt. Digital results typically land in your inbox within two days after the sample arrives.
If you require highly specialized testing, they collaborate with a UKAS-accredited referral facility to get you those tests you need.
The facility is a CQC-regulated diagnostic space that mirrors the equipment found in national health services. Testing here is also backed by rigorous internal controls and external quality-assurance programs.
One drawback is their strict policy on order changes. You can’t update a delivery address once confirmed, and canceling an order gets you only a partial refund.

Helpful Support for Research Sample Testing
I contacted London Health Company because I wanted to find a clinical laboratory to test the levels of cholesterol in the serum samples I use for research. They gave me helpful advice on how they could measure this for me, and despite some issues with Royal mail delivery losing my package they let me send my samples again for free. I am very happy with my results and will be using this service again in the future.

3. Clinilabs
Website: https://www.clinilabs.co.uk/
Address: 41-42 Foley Street
Contact: +44 204 525 8805 | [email protected]
Hours: Mon – Fri 8:00 AM – 6:00 PM, Saturday 10:00 AM – 4:00 PM, Sunday Closed
If you’re exploring sexual health clinics in London for screenings, you can book related health checks at Clinilabs without a GP referral. This direct access lets you take charge of your wellbeing on your own schedule.
The company operates its own CQC-regulated and UKAS-accredited in-house laboratory, participating in dozens of national external quality-assurance schemes.
And I love that if you book before the early afternoon cut-off, many eligible tests yield results on the exact same day.
Patients with specific requests can even reach out via WhatsApp to set up custom testing profiles.
While this flexibility is amazing, there are a few restrictions to consider. You need to be over 16 to attend a clinic appointment, and pediatric home visits are strictly subject to availability.
Also, blood draws and sample handling carry a separate collection fee on top of the listed test price. You can reduce this cost slightly by paying online beforehand, but it remains an extra expense.

4. Marylebone Diagnostic Centre & Laboratory
Website: https://www.marylebonediagnosticcentre.com/
Address: 73 Baker Street
Contact: Phone 020 77 240 540 | WhatsApp +447495970109 | [email protected]
Hours: Mon – Sat: 8:00 AM – 4:00 PM, Sun: Closed
Marylebone Diagnostic Centre is a great hub for comprehensive patient care. They offer services that extend beyond routine blood checks to include couples’ fertility assessments and genetic testing.
I recently visited this facility to ask about their specialized pathways, and the staff was exceptionally knowledgeable.
They operate an in-house laboratory that allows them to keep tight control over the testing process, ensuring most results are ready within two working days. Same-day appointments and walk-ins are also an option if they’re not too busy.
The diagnostic center is fully CQC-regulated, offering direct self-referral testing so you can bypass the GP waitlist entirely.
One significant downside involves their policy on unsuccessful sample collections. If a blood draw is attempted but can’t be completed, the clinic might retain half of the service fee to cover materials.
Any repeat attempt is offered entirely at the clinic’s discretion, which can be annoying if you have difficult veins.

5. Medlabs Diagnostic
Website: http://www.medlabs.uk/
Address: 1 Portpool Ln
Contact: [email protected] | +44 2080581556 | +44 7745795699
Hours: Mon – Fri 9:00 AM – 5:00 PM, Sat 8:00 AM – 2:00 PM, Sun: Closed
MedLabs Diagnostic has a team of multilingual phlebotomists and ultrasound specialists, helping ensure patients can communicate clearly and feel totally comfortable during their visits.
Navigating healthcare can be stressful, so speaking with friendly staff who understand your exact needs makes a noticeable difference.
The facility offers a broad diagnostic range, covering private blood panels and non-invasive imaging like echocardiograms.
Patients can book these private diagnostic services directly without a GP referral, and grab same-day appointments when available.
I love that most routine test results are securely delivered online within 24 hours. But specialized genetic or virology tests may take up to two weeks to process.
Also, they don’t offer medical advice or clinical follow-ups. You’re responsible for discussing your lab reports with your own healthcare professional or consulting nutritionists in London to interpret dietary-related panels.

Compassionate Blood Testing for Children
I have been using Medlabs Diagnostic for several years, especially for my children, and I honestly cannot recommend them enough. The team is incredibly professional, kind, and patient, making every visit as comfortable and stress-free as possible. Blood tests for children can be very difficult, but the staff are amazing with kids. I honestly don’t know where I would take my children for blood tests if this laboratory didn’t exist. Thank you for your outstanding care, professionalism, and dedication. I highly recommend Medlabs Diagnostic to anyone looking for reliable and compassionate service.
