WebHemostasis occurs when blood is present outside of the body or blood vessels. It is the innate response for the body to stop bleeding and loss of blood. During hemostasis three steps occur in a rapid sequence. Vascular spasm is the first response as the blood vessels constrict to allow less blood to be lost. WebADP causes platelets to aggregate (clump), reducing the transmission of light through a test tube. Early investigations suggested platelet resistance was an absolute change in aggregometry of <10%. This definition did not normalize for baseline activity and introduced some error into the assay.
