BLOOD PLATELET INHIBITION RATE CALCULATION METHOD BASED ON THROMBOELASTOGRAM

摘要

A blood platelet inhibition rate calculation method based on a thromboelastogram. The method comprises: testing a blood sample to obtain a thromboelastogram, wherein the thromboelastogram comprises a maximum coagulation intensity MA_t curve, a minimum coagulation intensity MA_f curve and a blood platelet coagulation curve f(t) after the blood sample coagulates; transforming coordinate axes of the curves of the thromboelastogram, and translating an X axis to the position of a symmetry axis of the three curves; integrating a numerical amplitude value of a coagulation intensity that is obtained by testing, and a coagulation time value, and respectively calculating an integral coagulation intensity DI_t of the maximum coagulation intensity MA_t curve, an integral coagulation intensity DI_f of the minimum coagulation intensity MA_f curve, and an integral coagulation intensity DI of the coagulation curve f(t); and calculating a blood platelet inhibition rate BPI = (1 - (DI - DI_f)/(DI_t - DI_f)) × 100%. An evaluation result obtained by means of the calculation method is more accurate and can correctly reflect the actual state in which blood platelets are inhibited after the use of a blood platelet inhibition drug.
