Age-based inter-subject variability in platelet and white blood cell concentrations of platelet-rich plasma prepared using a new application to blood separation system.

PMID: 34114747; PMCID: PMC8762541.https://hdl.handle.net/10115/40654The benefit of autologous platelet-rich plasma (PRP) treatment is still under discussion. Variations in PRP products, consequence of the lack of a standardised protocol for the multitude of commercially available blood separation systems and the lack of knowledge of the optimal composition of PRP or its suitability for the proposed indication are some of the reasons behind clinical inconsistencies. The impact of inter-subject variability in PRP has received less attention in comparison. The purpose of this study was to determine the inter-subject variability, based on age, in the concentrates prepared by a new blood concentration system. Twenty-six healthy volunteers of both genders (29-93 years) were enrolled. Whole blood (WB) was collected from each participant to prepare PRP using the Easy PRP kit. Platelets and white blood cells (WBC) from WB and PRP were analysed after split population by age; patients younger than 65 years (n = 13) and patients ≥65 years old (n = 13).
