Automated method and device for identifying and quantifying platelets and for determining platelet activation state using whole blood samples |
摘要 |
The present invention provides a highly sensitive and accurate method and system for the discrimination and quantification of platelets in a whole blood sample using automated hematology instruments. The method and system of the invention provide the accurate measurements of platelet dry mass and platelet component concentration in both normal blood samples and in abnormal blood samples, such as those from thrombocytopenic patients. The determination of platelet dry mass and platelet component concentration can serve to assess the activation state of platelets since activated platelets possess measurably lower component concentrations and refractive indices than do unactivated platelets. The method and system of the invention also allows the clinician or skilled practitioner to determine the age of a blood sample on the basis of the measured parameter of platelet component concentration.
