DETERMINATION OF INTERNATIONAL NORMALIZED RATIO (INR) BASED ON CAPILLARY BLOOD PROTHROMBIN TIME (PT)

摘要

FIELD: medicine, in particular laboratory diagnosis of hemopexis system damage useful in anticoagulant therapy control.;SUBSTANCE: hematocrit is determined in capillary blood of subject; then PT value is twice measured, and mean value is calculated. Said mean value is correlated with PT value of normal plasma and INR is calculated according the formula including coefficient which depends on hematocrit value and International index of thromboplastin reagent sensitivity.;EFFECT: standardized PT value-based method for INR value determination of improved accuracy.;2 cl, 1 tbl, 3 ex, 1 dwg
