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.
In practice
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.
