Key takeaways
- Compare quotes on what is written down: cell source, viable count, lab documents, guidance, follow-up and exclusions.
- Send identical information and questions to both clinics so the answers line up.
- A bigger cell number means little without viability, method and timing.
- Count the “not stated” cells; blanks and vague wording often matter more than the price gap.
On this page
You have two quotes from two Colombian stem cell clinics. One is cheaper. One promises more cells. Both PDFs look professional, and both coordinators are friendly on WhatsApp. How do you actually compare them?
The trick is to stop comparing the bottom-line price and start comparing what each clinic is putting in writing. Lay the quotes side by side on the same template, line by line: cell source, how many living cells, lab documentation, how the injection is guided, follow-up, and what is not included. Gaps and vague wording usually tell you more than the number at the bottom. This guide gives you that template and explains how to read each row.
Why price alone is the wrong comparison
Two quotes at different prices can describe completely different products. One might be a same-day injection of your own processed fat tissue. The other might be a culture-expanded donor product with a lab certificate, an imaging-guided injection and six months of follow-up calls. Those are not the same purchase, even if both are labeled "stem cell therapy."
Cost differences usually come from a handful of drivers: the type of cell product, whether cells are expanded in a lab, how much testing documentation exists, the physician's time, imaging guidance, anesthesia or sedation, facility fees, and what is bundled for lodging and transport. Our complete cost breakdown goes into each of these. Here, we focus on comparing two quotes you already have.
Step one: get both quotes into the same shape
Clinics format quotes differently on purpose and by habit. Before you compare, ask each clinic the same set of questions in writing so the answers line up.
- Send the same information to both. Same imaging, same history, same goals. If one clinic quoted without seeing your MRI, that is already a data point.
- Ask for an itemized quote. Product, procedure, physician fees, facility, imaging guidance, labs, medications, follow-up. A single lump sum hides the details you need.
- Ask the same follow-up questions. Use the template below and send it to both clinics word for word.
- Get everything in writing. A WhatsApp voice note is not documentation. Ask for an email or a signed PDF.
- Fill in the template. Mark anything missing or vague as "not stated" rather than guessing.
The side-by-side comparison template
Copy this table into a spreadsheet or onto paper and fill in one column per clinic. The third column tells you what a strong answer generally looks like.
| Line item | Clinic A | Clinic B | What a clear answer looks like |
|---|---|---|---|
| Cell source | Named tissue (your bone marrow, your fat, umbilical cord tissue, other) and whether it is autologous or donor | ||
| Same-day or culture-expanded | Stated clearly, with the lab that processed it | ||
| Cell count and how measured | A number with the method used and the point at which it was counted | ||
| Viability | Percentage of living cells, with the test method and timing | ||
| Lab documentation | Certificate of analysis covering identity, sterility, endotoxin, mycoplasma, and donor screening for donor products | ||
| Regulatory status | How the product and facility are authorized in Colombia, in writing | ||
| Route and number of injections | Exact sites, local vs IV, how many sessions | ||
| Image guidance | Ultrasound or fluoroscopy, and who performs it | ||
| Treating physician | Name, specialty and verifiable credentials | ||
| Anesthesia or sedation | Type, and who administers it | ||
| Pre-treatment labs and consult | Included or extra, and which tests | ||
| Medications | What is included and what you must buy | ||
| Follow-up | Schedule, format (in person, video), duration, and outcome measures | ||
| Complication plan | Who you call, where you go, and who pays | ||
| Exclusions | A written list of what is not included | ||
| Payment and refunds | Deposit terms, cancellation policy, what happens if you are found not to be a candidate on arrival |
How to read the rows that matter most
Cell source
This is the first row because it changes everything else. Autologous bone marrow or fat means your own cells, harvested the same day, with a harvest procedure added. Donor products, such as umbilical cord tissue, skip the harvest but bring donor screening and lab quality to the front. Neither is automatically better. What matters is that the quote names the source plainly. Background: umbilical vs adipose vs bone marrow cells.
Cell count and viability
A bigger number is not automatically a better quote. Ask what was counted (all nucleated cells, or a specific cell type), when it was counted (at the lab or at your bedside), and how many were alive. A quote that says "100 million cells" without saying how many are viable at the time of injection is incomplete. Our articles on what cell counts mean and why 100 million cells does not mean 100 million living cells go deeper.
Lab and testing documentation
For any processed or donor product, ask to see a sample certificate of analysis before you pay a deposit. It should cover identity, sterility, endotoxin and mycoplasma testing, and donor screening where relevant. If one clinic sends documents promptly and the other says "we'll show you when you arrive," that is a meaningful difference. See what a certificate of analysis should show.
Imaging guidance
For joint, tendon and spine injections, ultrasound or fluoroscopy guidance helps confirm the injection lands where intended. If one quote includes guided injection and the other is silent, ask directly. A cheaper quote that injects by feel is not comparable to a guided one.
Follow-up
Follow-up is where many quotes are thinnest. "Follow-up included" can mean a single WhatsApp check-in or a structured schedule with function scores at set intervals. Ask how they track results and whether they share their data. Our piece on patient registries and outcome tracking explains what good follow-up looks like.
What is commonly left out
Exclusions are where the surprise costs live. Ask each clinic to confirm, in writing, whether these are included.
- Pre-treatment imaging or labs done in Colombia
- Specialist consultation fees separate from the procedure
- Sedation or anesthesia professional fees
- Prescription medications and braces or boots
- Physical therapy sessions in Colombia
- Airport transfers, lodging and interpreter services
- Additional sessions if the physician recommends them on arrival
- Care for complications, including hospital admission
- Records, imaging discs and translated reports to take home
Ask each clinic what happens if, after examining you in person, the physician recommends a different or larger protocol. A clear answer is something like "we'll explain why, give you a revised written quote, and you can decline." Vague answers here are worth noting.
Red flags when comparing quotes
- A quote issued without reviewing your imaging or history.
- Specific success percentages with no source. See interpreting clinic success percentages.
- Pressure to pay a deposit quickly, or "discount expires Friday" messaging.
- Claims to cure or reverse a condition.
- Refusal to name the treating physician or the lab.
- No written plan for complications.
More warning signs are collected in our red flags guide.
A message you can send to both clinics
Coordinators answer the question you ask, so ask precisely. You can paste something like this into an email to each clinic, adjusting the condition and dates.
Thank you for the quote. Before I decide, could you confirm the following in writing? (1) The exact cell source and whether it is processed the same day or culture-expanded, and by which lab. (2) The cell count, how it is measured, and the expected viability at the time of injection. (3) Whether you can send a sample certificate of analysis. (4) Whether the injection is ultrasound- or fluoroscopy-guided, and the name of the treating physician. (5) The follow-up schedule and what outcomes you measure. (6) A list of everything not included in the price. (7) Your deposit, cancellation and refund terms, including if I am found not to be a candidate on arrival.
How a clinic responds to a clear, polite list like this is part of the comparison. Fast, specific, documented answers are a good sign. Defensive or evasive replies, or a sudden discount instead of answers, are worth weighing. If you are still early in the process, our broader questions for choosing a stem cell clinic are a good starting list.
Making the call
Once both columns are filled in, count the "not stated" cells. The clinic with fewer blanks, clearer documentation and a realistic conversation about your expected outcome is usually the stronger quote, even if it costs more. If both are full of blanks, that may be a sign to keep looking.
Ask each clinic for a short video call with the treating physician, not just the coordinator. Spending 15 minutes with the doctor who will actually inject you, and hearing them explain your case, tells you a lot about how the clinic works.

Frequently asked questions
Is the cheaper stem cell quote always worse?
Not necessarily. A lower price can reflect a simpler, same-day procedure that may be appropriate for your case. What matters is whether the quote is clear about what you get and whether that matches your diagnosis.
What documents should a clinic send before I pay a deposit?
At minimum, an itemized written quote, the treating physician's name and credentials, and for processed or donor cells, a sample certificate of analysis. Also ask for the cancellation and refund policy in writing.
Should a clinic quote me without seeing my MRI?
A responsible clinic generally needs your imaging and history to decide whether you are a candidate. A quote issued without them is really a price list, not a treatment plan.
What if the clinic changes the plan after I arrive?
Ask in advance how this is handled. You should get an explanation, a revised written quote and the option to decline without pressure.
Can you review my two quotes?
Yes. Send them through our contact form with your imaging, and we'll help you compare them and figure out which questions to ask next.
