Abstract
Provided is an accelerated method for preparing platelet rich plasma (PrP) without centrifugation or filtration. The method comprises contacting a sample of whole blood with an anti-coagulant and an inducer of Rouleaux formation; allowing the mixture to stand thereby depleting the sample of RBCs, and collecting the platelet-rich plasma fraction. The PrP volume obtained by the present method is about 10-60% of the volume of the starting whole blood sample, and contains less than 200,000 RBCs and at least 100,000 platelets per microliter.
