A rapid, automated flow cytometric method to measure activated degranulated platelets by density determination.

摘要

Platelet activation is reported to correlate with acute coronary syndromes. A platelet analysis method on the ADVIA(R) 120 Hematology System provides rapid analysis of platelet density, reported as mean platelet component (MPC) concentration, utilizes routine hematology specimens, requires no pre-treatment, and thirty seconds to generate results. Sub-populations of platelets separated by density gradients showed excellent correlation with the ADVIA 120 MPC parameter (r = 0.997). Platelet activation induced by thrombin treatment resulted in a shift of platelets into the lowest density fraction (d
