Whole blood laboratory model of thrombocytopenia for use in evaluation of hemostatic interventions.
This study describes a laboratory model of whole blood (WB) thrombocytopenia established with blood from healthy volunteers. We obtained a mean platelet count of 16 x 10(9)/l (95% confidence interval, 10-22) in WB by repeatedly replacing the platelet-rich supernatant with autologous platelet-poor plasma from the same individual. ⋯ Control experiments revealed minimal changes in coagulation factors, distribution of bloods cells, and platelet activation capabilities. The WB model appears useful in research, development, and evaluation of the effects of hemostatic interventions in thrombocytopenia.
