--- title: Platelet concentration factor url: https://regenmedtools.com/glossary/platelet-concentration-factor/ type: glossary primaryQuery: platelet concentration factor prp --- # Platelet concentration factor Concentration factor is how many times the platelet count in the final product exceeds the patient's whole-blood baseline, written for example as 5x. It is a property of the protocol and the patient, never of the machine alone. Because baseline platelet count varies with age, sex, nutrition, hydration, and health, a protocol reported at 5x baseline in a study will not produce the same absolute platelet count in every patient. Absolute count, not multiple, is what reaches the tissue. ## Related - [prp](https://regenmedtools.com/glossary/prp/) - [thrombocyte](https://regenmedtools.com/glossary/thrombocyte/) - [haematocrit](https://regenmedtools.com/glossary/haematocrit/)
