ABSTRACT:
An instrument is described for measuring the platelet aggregation in whole blood in response to standard aggregating agents. The instrument is designed to be used in the clinical laboratory to evaluate the functional status of platelets in blood samples drawn from patients suspected of abnormal platelet function, or in a research laboratory to evaluate the effectiveness of platelet agonists or antiplatelet agents. The measurement is based on the scattering of light in the blood sample and does not require separation of erythrocytes from blood and therefore helps minimize the need for handling of blood by the laboratory personnel. The instrument converts the light-scattering data to provide the number and average size of the aggregates per unit volume at various times during the process of aggregation.
