Frequently Asked Questions
Who are GC Biosciences?
GC Biosciences is a UK-based clinical health optimisation company operating from Harley Street, London. We are a registered UK company (Companies House No. 08346259). Our founders, Rob Corney and Calum Gore, are named consultants with verifiable professional backgrounds. We specialise exclusively in blood chemistry, metabolic health, longevity, and healthspan using lifestyle interventions such as nutrition counseling, exercise prescriptions, supplement and medication recommendations. We combine clinical-grade diagnostics with personalised coaching to help clients understand and actively improve their health.
Are you a regulated healthcare company?
GC Biosciences is a registered UK company (No. 08346259), verifiable at companieshouse.gov.uk, we are also registered with the Care Quality Commission (Pending). We operate from Harley Street, one of the most regulated private medical addresses in the world. All blood samples are processed by UKAS-accredited laboratories, the same accreditation required by NHS pathology labs. Our practitioners have verifiable qualifications and professional backgrounds that can be researched independently
Where are you based?
Our clinical team is based on Harley Street, London, one of the most recognised and regulated private medical addresses in the world. However, the programme is available nationwide and internationally. A qualified phlebotomist visits you at your home or office for the blood draw, so you never need to travel to us.
THE TESTING
How do I know my blood results are accurate and trustworthy?
Every blood sample is drawn by a qualified phlebotomist using a full venous draw, not a consumer finger-prick kit (which are unreliable by many tests. Your sample is then processed by a UKAS-accredited laboratory, which means it operates under the exact same quality standard as NHS pathology labs. The raw results come directly from the lab. GC Biosciences interprets them, we do not generate them. You can verify our laboratory accreditation independently at ukas.com. We also actively encourage clients to share their results with their NHS GP.
What is the difference between a venous blood draw and a finger-prick test?
A venous blood draw, the method used by hospitals and clinics producing a larger, cleaner sample that allows accurate measurement of a much wider range of markers. Finger-prick tests produce a smaller capillary sample that can be affected by dilution, contamination, or poor technique, leading to less reliable results. The quality of the sample directly affects the quality of the data. We do not compromise on this.
What markers do you test and why those specifically?
We test 50+ clinically relevant biomarkers across cardiovascular health, metabolic function, hormones, inflammation, and nutrient status. Every marker in our panel is included because something can be done about it, a nutrition change, a supplement, a lifestyle intervention. We do not run markers simply to inflate the number. More markers does not mean better insight. We run the right ones and tell you exactly what to do about every result.
What is the difference between "normal" and "optimal" ranges?
Clinical reference ranges — used by GPs and most testing providers — are designed to identify disease. They tell you whether you have crossed a threshold that requires medical intervention. They are not designed to tell you whether you are healthy. Optimal ranges reflect where your markers should sit for genuinely good health, peak metabolic function, and low long-term disease risk. Many people are told their results are “normal” while their biology is quietly heading in the wrong direction. We work to optimal ranges, not clinical ones.
THE BLOOD DRAW
Who performs the blood draw?
All blood draws are performed by a qualified, professional phlebotomist. They come to your home or office at a time that suits you. The process takes around 10 minutes and is completely routine. We walk you through exactly what to expect before the appointment so there are no surprises.
What should I expect on the day of the blood draw?
Your phlebotomist will arrive at your home or office at your scheduled time. You will be asked to have fasted for around 8 to 10 hours beforehand (water is fine). The draw itself takes approximately 10 minutes. The sample is then sealed and sent directly to our accredited laboratory. Most clients find the experience completely straightforward and far less clinical than they expected
Is a home blood draw available everywhere in the UK?
We cover most of the UK through our nurse network. When you book your consultation, we will confirm availability in your area. We also have clinic locations at Harley Street and Wimpole Street in London for clients who prefer a clinic setting.
THE PROGRAMME
How is this different from just getting a private blood test?
A private blood test gives you data. GC Biosciences gives you a plan, a person, and proof. After your results are interpreted by our clinical team, you receive a blood-matched nutrition strategy, a personalised supplement protocol, and a dedicated nutritionist who works with you for 90 days, weekly check-ins, WhatsApp support, and full accountability. At the end of the programme we retest everything and show you in numbers what changed. Data without action is just noise.
How is this different from going private with Bupa or Nuffield?
Private healthcare is reactive, you go when something is wrong. A generalist GP has 10 minutes and a broad remit. GC Biosciences is proactive and specialist. We work exclusively in blood chemistry, metabolic health, and clinical nutrition. We catch risk before it becomes a problem, build a plan specific to your biology, and walk alongside you for 90 days. No private hospital offers an ongoing coaching relationship as standard.
How is this different from Medichecks, Thriva, or Randox?
Those companies send you a report and the relationship ends. There is no interpretation specific to your situation, no nutrition plan, no coaching, and no accountability. GC Biosciences tells you what every result means for your health, builds a personalised plan around your biology, and coaches you through it with a dedicated nutritionist. We also use a full venous draw rather than a finger-prick kit, which produces significantly more reliable data.
What does the 90-day programme include?
The programme includes: comprehensive blood testing with two at-home nurse visits, PhD-level clinical interpretation against optimal ranges, your personal 360 Health Blueprint, a blood-matched nutrition strategy, a personalised supplement and medication protocol where appropriate, a dedicated nutritionist with weekly check-ins and WhatsApp support for 90 days, and a full retest with before-and-after biomarker comparison at the end. Investment and availability are discussed on your free consultation call.
What is the Biomarker Improvement Guarantee?
If your key biomarkers do not improve after completing the programme and following the protocol, we keep working with you at no additional cost until they do. We measure our success by your results, not your enrollment.
Why do you only take 20 clients per month?
Each client has a dedicated nutritionist, weekly check-ins, and active clinical oversight for the full 90 days. Quality of support is non-negotiable and cannot be scaled beyond that without compromising it. When monthly spaces are taken, the next available intake is the following month.
GETTING STARTED
How do I get started?
The best first step is to take our free 3-minute health quiz. It assesses your current risk across cardiovascular, metabolic, hormonal, and energy markers and tells you which areas of your biology need attention first. From there you can book a free 30-minute health consultation where we will walk you through the right option for where you are now.
Is there a lower commitment option if I am not ready for the full programme?
Yes. Our Precision Health Diagnostic includes the full blood test, a home nurse visit, PhD-level clinical interpretation, and your 360 Health Blueprint. It gives you everything you need to understand your biology in full, without the ongoing coaching commitment. It is a strong starting point for anyone who wants the clinical picture before deciding on next steps.
Can I share my results with my NHS GP?
Absolutely, and we actively encourage it. Your results come from a UKAS-accredited laboratory using standard clinical formatting and reference ranges, so they are immediately readable by any GP or clinician. A company confident enough to invite independent verification has nothing to hide.
