Potency: biological activity versus marketing strength
Potency testing concerns a product’s intended activity, not simply a high cell count.

What potency tries to capture
For a cell product, potency relates to biological activity relevant to its intended effect. The appropriate measurement depends on what the product is designed to do. It may require more than one test because living products can act through complex mechanisms. A statement that a product is highly potent is incomplete without identifying the activity, test, and acceptance criteria behind the claim.
Why cell numbers are not enough
Two preparations with the same number of living cells may behave differently. Their identity, condition, processing history, and functional properties can vary. Counting cells is therefore not a complete substitute for assessing activity. Patients should be cautious about treatment comparisons based only on millions of cells or the concentration of a vial.
A test is not a patient outcome
A potency assay can support manufacturing consistency, but it is not automatically a direct prediction of an individual patient’s improvement. The relationship between laboratory activity and clinical benefit has to be established through research. Ask how the measured activity connects with the proposed mechanism and which human outcomes support the treatment.
What to request from a provider
Ask whether the final product has a defined potency strategy and whether the administered batch meets its specifications. For a clinic-created preparation, ask what evidence shows that the preparation has the activity being claimed. A clear answer should distinguish process control, laboratory activity, and clinical effectiveness. Those three layers contribute different information to a treatment decision.
