NCT03161743

Brief Summary

This is a study to determine 1) the consistency of platelet-rich plasma produced by several methods, and 2) whether the platelet content of platelet-rich plasma can be accurately estimated from a baseline CBC platelet count.

Outcome Measures

Primary Outcomes (2)

  • Platelet yield

    the number of platelets in a PRP sample as a percentage of the number of platelets in the blood from which the PRP was prepared.

    within 8 hours of blood draw

  • Platelet yield estimate accuracy

    standard deviation of the difference between the estimated platelet yield and the actual platelet yield.

    within one month of final data collection

Interventions

venipuncturePROCEDURE

blood draw for the purpose of determining the platelet concentration in PRP
