A Simple Double-Spin Closed Method for Preparing Platelet-Rich Plasma
Objective: To describe and analyze a new protocol for the extraction of platelet-rich plasma (PRP) for use in
clinical practice and compare this technique with methods that have been previously described in the
medical literature.
Methods: Sixteen blood samples from healthy volunteers were collected. PRP was prepared using our new
double-spin technique, consisting of successive centrifugation of blood samples with two different spins,
without opening the container. Descriptive analysis of cell counts in baseline and PRP samples was
undertaken. Comparison between cell and platelet count in baseline and PRP samples, as well as the
statistical analysis, were done.
Results: The mean platelet concentration ratio was 3.47 (SD: 0.85; 95% CI: 3.01-3.92; range: 2.48-5.71). The
baseline whole blood platelet count correlated positively to the PRP platelet count (rP = 0.56; 95% CI: 0.09-
0.88; P = 0.023). The PRP was enriched for lymphocytes and monocytes but presented significantly lower
counts of neutrophils and eosinophils in comparison to baseline.
Conclusion: Results show a safe and easily reproducible method to obtain PRP for use in clinical daily
