The Questions That Matter
Choosing a stem cell clinic in Colombia is one of the most consequential medical decisions you'll make. The right clinic can offer a safe, effective, well-monitored treatment experience. The wrong one can waste your money — or worse, put your health at risk. These are the questions that separate credible, INVIMA-regulated operations from marketing-first clinics that cut corners.
We've organized these questions into categories. Print this list, bring it to your consultation, and pay attention not just to the answers but to how comfortable the clinic is answering them. Legitimate operations welcome scrutiny.
About the Cells
"What type of stem cells do you use, and where do they come from?" The answer should specify: mesenchymal stem cells (MSCs), the source (Wharton's jelly, bone marrow, adipose tissue), and whether they're allogeneic (donor-derived) or autologous (your own). Most Colombian clinics use allogeneic Wharton's jelly MSCs, which is the current gold standard for potency and safety.
"What passage number are the cells?" Passage-3 is the industry standard. Lower passages (P1–P2) mean fewer cells but potentially higher per-cell potency. Higher passages (P4+) may have reduced differentiation capacity. If the clinic can't tell you the passage number, that's concerning.
"How many cells will I receive?" The answer should be a specific number (e.g., "50 million MSCs for a joint injection" or "150 million across three IV sessions"). Vague answers like "millions of cells" are insufficient. Cell count directly affects both efficacy and cost.
"What is the cell viability rate?" This measures what percentage of the cells are alive and functional at the time of treatment. Legitimate labs test viability for every batch. You should expect 90%+ viability; below 85% is substandard.
About the Lab
"Is your laboratory INVIMA-certified?" This is non-negotiable. Ask for the certification number and verify it. If the clinic uses a third-party lab (which is common — not all clinics have in-house processing), the lab should be INVIMA-certified.
"Does the lab follow GMP standards?" Good Manufacturing Practice compliance means controlled environments, documented processes, quality testing at every stage, and full traceability. This isn't optional — it's the baseline for safe cell therapy.
"Can I see sterility and testing documentation?" Every batch of cells should come with a certificate of analysis showing sterility testing (no bacteria, fungi, or viruses), endotoxin testing, mycoplasma testing, and viability results. If a clinic can't produce this documentation, walk away.
About the Protocol
"Why is this specific protocol appropriate for my condition?" The physician should be able to explain the rationale: why this cell type, why this cell count, why this delivery method, and what evidence supports this approach for your specific condition. Generic answers suggest a one-size-fits-all approach.
"How many patients with my condition have you treated?" Experience matters. A clinic that has treated 500+ orthopedic patients but only 10 neurological patients is better suited for the former. Don't be afraid to ask for specific numbers.
"What outcomes do you typically see?" Good clinics track outcomes systematically using standardized measures (VAS pain scores, WOMAC for joints, IIEF for ED, UPDRS for Parkinson's). Be cautious of clinics that rely exclusively on testimonials — subjective reports are valuable but insufficient.
About the Physician
"What are your qualifications and training in regenerative medicine?" Verify the physician's credentials through Colombia's ReTHUS system. Look for training in regenerative medicine, sports medicine, orthopedics, or the relevant specialty for your condition. Board certification in a relevant field is a strong positive signal.
"Will you be the one performing my procedure?" Know who will actually be in the room. At some clinics, the consulting physician is different from the treating physician. This isn't necessarily a problem, but you should know in advance.
About Follow-Up
"What does your follow-up protocol look like?" Legitimate clinics schedule virtual follow-up consultations at regular intervals — typically 30 days, 90 days, 6 months, and 12 months. They should use standardized outcome measures to track your progress objectively.
"What happens if I don't respond to treatment?" Honest clinics acknowledge that not every patient responds. Ask what their protocol is for non-responders — do they offer booster treatments? Adjusted protocols? Refunds? The answer tells you a lot about the clinic's confidence and integrity.
"How do I reach you after I return home?" You should have a direct communication channel (email, WhatsApp, patient portal) with the clinical team — not just a sales coordinator. Post-treatment questions and concerns should be answered by medical staff.
Red Flags Checklist
The clinic guarantees specific outcomes ("we'll cure your Parkinson's"), cannot provide INVIMA certification or cell testing documentation, pressures you to commit immediately with "limited availability" tactics, won't specify cell type, count, or passage number, has no structured follow-up protocol, quotes prices dramatically below market rates without explanation, or dismisses your questions as unnecessary or overly technical. These are signs of a clinic that prioritizes sales over patient care.
Green Flags Checklist
The clinic proactively shares INVIMA documentation and cell testing results, uses standardized outcome measures to track patient progress, can cite specific patient volumes for your condition, offers transparent pricing with clear package inclusions, provides honest evidence assessments ("the data is promising but not definitive"), has a structured follow-up protocol extending 6–12 months, and encourages you to take your time with the decision. These signal a patient-first operation.
