Your Cancer Concerns Are
Unique.
Your Tests Should Be Too.
The RGCC International "Greek Test" is a liquid biopsy test that detects and analyzes circulating tumor cells (CTCs) in your bloodstream — providing detailed laboratory data on how your cells respond to a wide range of agents, both conventional and natural. Dr. Murray uses this information to support informed, personalized health discussions.
Advanced laboratory testing that provides detailed, personalized cellular data — so your health conversations are guided by your biology, not someone else's statistics.
Precision Oncology Data Meets
Integrative Functional Medicine
The RGCC Greek Test is an advanced liquid biopsy — a blood test that detects and analyzes circulating tumor cells (CTCs) in your bloodstream. Unlike standard cancer blood markers, RGCC actually isolates your tumor cells and tests them against a comprehensive panel of treatments.
According to RGCC, the result is a personalized laboratory report showing how your circulating tumor cells respond to chemotherapy agents, targeted therapies, and natural compounds under controlled lab conditions. No two reports look alike — because no two people's cellular biology is the same.
Founded in 2004 by Dr. Ioannis Papasotiriou, RGCC International operates accredited laboratories worldwide and has published peer-reviewed research on its laboratory testing methodology.
It is important to understand that RGCC testing does not replace comprehensive diagnostic evaluation or the care of a licensed oncologist. If you have cancer concerns, seeking care from a qualified oncologist remains essential. What RGCC testing does is add another layer of data and clarity — personalizing nutritional and supportive approaches for those navigating cancer concerns, and helping inform more complete conversations between patients and their entire care team.
Three Reasons Informed
Patients Are Asking About This Test
Data, Not Assumptions
Many protocols are population-level based, not individual biology. RGCC laboratory testing provides detailed cellular response data specific to your sample — so your health decisions can be informed by your own biology.
Natural Compounds Evaluated
RGCC's laboratory panel tests over 50 natural compounds — including medicinal mushrooms, curcumin, and botanical extracts — against your circulating tumor cells under lab conditions, generating data to support informed conversations about your natural health protocols.
Early Detection Advantage
According to RGCC, circulating tumor cells can be detectable in the bloodstream before symptoms develop. For those seeking proactive monitoring or with a family history of cancer, RGCC testing provides cellular-level data that goes beyond standard screening markers.
Choose the Test
That Fits Your Situation
Dr. Murray will help you identify the most appropriate test during your consultation. The right choice depends on your health history, your goals, and the type of cellular information most relevant to your situation.
Onco-D-Clare
According to RGCC, this test is designed to assess cancer risk indicators before symptoms appear. It provides laboratory data that may be relevant for prevention-minded individuals with a family history or elevated risk factors seeking information beyond standard screenings.
Oncocount + Oncotrace
According to RGCC, these tests detect, count, and characterize circulating tumor cells in a blood sample, establishing a personal cellular baseline. Results can be used to track changes over time in consultation with your healthcare providers.
Onconomics
According to RGCC, this test exposes circulating tumor cells to specific chemotherapy agents and targeted therapies under lab conditions, generating a report on cellular sensitivity. This laboratory data may support informed discussions with your oncologist about treatment options.
Metastat
According to RGCC, this test investigates proteins associated with cancer cell migration and spread, providing laboratory insight into metastatic potential. Results are intended to support clinical discussions, not replace oncological evaluation.
Onconomics Plus — The Complete Picture
This is the most comprehensive test provided by RGCC labs, combining conventional drug sensitivity data with a panel of 50+ natural compounds and plant extracts including medicinal mushrooms, curcumin, high-dose vitamin C, CBD, and more. The resulting laboratory report provides a detailed cellular response profile across both conventional and natural agents, supporting more informed conversations about integrative health strategies with your care team.
Laboratory Data on
Your Natural Protocols
Many people using natural health approaches rely on general research or population-level studies. RGCC's Onconomics Extracts panel tests your circulating tumor cells against natural compounds under laboratory conditions — providing personalized cellular response data rather than generalized statistics.
"I finally had laboratory data to bring to my care team. Instead of guessing which supplements made sense for my situation, I had an actual report showing my cellular response. That clarity changed every conversation I had with my providers."— RGCC testing patient, 4 years post-diagnosis (illustrative; individual results and experiences vary)

One of the Country's Most
Credentialed RGCC Practitioners
Dr. Murray brings a rare combination to RGCC testing: the diagnostic rigor of a board-certified naturopathic physician, the functional medicine depth of 20+ years of root-cause clinical practice, and the teaching authority of a faculty member who educates medical doctors across the country.
His philosophy is simple: the body has an innate ability to heal when given the right conditions. Drugs and surgery have their place — but the goal is always to find the cause, not just manage the symptom. RGCC testing is the most powerful tool he has encountered for personalizing that process.
Dr. Murray brings this expertise to individuals seeking advanced laboratory testing — ordering tests, reviewing results, and discussing personalized integrative wellness strategies. Consultations are available by appointment.
RGCC Testing Is Right
For You If…
You Have an Active Diagnosis
You want detailed laboratory data about how your own cells respond to various agents — not just population-level statistics from someone with a similar diagnosis. RGCC provides a personalized cellular report to inform your conversations with your care team.
You're in Remission
You want more information between standard appointments. RGCC monitoring tracks circulating tumor cell levels over time, providing laboratory data that may support more informed conversations with your oncologist about your ongoing health status.
You Have a Family History
Cancer runs in your family and you're committed to proactive monitoring. The Onco-D-Clare test provides cellular-level laboratory data that may complement standard genetic screening as part of a comprehensive wellness strategy.
You're Using Natural Protocols
You're taking supplements, following a specialized diet, and using integrative therapies — and you want laboratory data on how your circulating tumor cells respond to those compounds specifically, to better inform your wellness approach.
You're a Caregiver
You're advocating for a loved one and want personalized laboratory data to support more informed conversations with every member of their care team. RGCC's reports provide cellular-level information that goes beyond general population data.
You Want a Second Opinion
You've received a conventional treatment plan and want additional laboratory data about your specific cellular biology — to support a more complete, informed discussion with your oncologist and integrative health team.
