The clinic is what you see. The laboratory is what matters. Your stem cells are processed, expanded, tested, and prepared for delivery in a lab — and the quality of that lab determines whether you receive a safe, viable, properly characterized cell product or a contaminated, low-viability preparation that will not work. These 12 questions audit the lab behind the clinic.
Never book stem cell treatment without asking about the laboratory. The clinic may be beautiful; the lab may be substandard. A legitimate lab will welcome your questions — it is a sign that you are a serious, informed patient.
| # | Question | Good Answer | Red Flag |
|---|---|---|---|
| 1 | Is the lab cGMP-certified or equivalent? | 'Yes — certified by INVIMA / national authority' | 'We follow GMP principles' (not the same as certification) |
| 2 | Can I see the Certificate of Analysis for my cells? | 'Yes — provided with every treatment' | 'We don't typically share lab reports' |
| 3 | What is the typical cell viability? | '>90% at time of delivery' | Vague or below 85% |
| 4 | How are cells characterized? | 'Flow cytometry: CD73+, CD90+, CD105+, CD34−, CD45−' | 'We test for viability only' |
| 5 | What passage number are the cells? | 'P2–P4' | Above P5 (cells may lose potency) |
| 6 | Is sterility testing performed? | 'Yes — bacterial, fungal, mycoplasma, endotoxin' | 'We test for sterility' (no specifics) |
| 7 | Who is the lab director? | Named person with relevant credentials | 'Our team handles it' |
| 8 | How are cells transported to the clinic? | 'Controlled temperature, documented chain of custody' | No temperature monitoring mentioned |
| 9 | Is the lab on-site or off-site? | Either is fine — but chain of custody must be documented | Lab location unknown or undisclosed |
| 10 | How long between cell preparation and delivery? | 'Same day or within hours' | Overnight or longer without proper storage |
| 11 | Are cells fresh or cryopreserved? | Clear answer either way — both can be valid | 'It depends' with no protocol explanation |
| 12 | Can I tour the lab? | 'Yes — we welcome patient visits' | 'That's not possible' |
