Analytical figures are not outcomes
Particle counts and growth-factor panels, when listed, are analytical. They are not proof of clinical performance.
Compare how each supplier ties figures to lots before comparing magnitudes.
Method matters
Ask about measurement method, dilution, and whether the number is lot-specific.
Brochure-only numbers are weak evidence for purchasing decisions.
Compare methods before magnitudes
List each candidate SKU by tissue type, presentation, storage class, and stated analytical fields. Ignore superlatives and disease-oriented marketing when building the shortlist.
Prefer suppliers that answer with documents over suppliers that answer with testimonials.
