Range: the ratio is 0.82-1.15 Significance of prothrombin time Three, activated partial thromboplastin time (activated partial thromboplatin time, APTT), normal reference value of 1: 24-36 seconds. Clinical application: 2, activated partial thromboplastin time (APTT) is a screening test of ...
The Clinical and Laboratory Standards Institute (CLSI) recently abandoned its recommendation for drawing a discard tube when performing a prothrombin time (PT)/international normalized ratio (INR) or an activated partial thromboplastin time (APTT). Because there is currently no evidence that a discard...
PT tube is used for blood coagulation test and applicable to fibrinolytic system(PT,TT, APTT and fibrinogen, etc. The mixing ratio is 1 part citrate to 9 parts blood. Accurate ratio can guarantee effectiveness of the testing result and avoid misdiagnosis. As the sodium citrate has ver...
CLSI EP28-A3c recommended Dixon’s D/R ratio outlier test to exclude outliers, where D is the absolute difference between the largest (or smallest) and the second largest (or smallest) observation, and R is the range of all observations. If D is equal to or greater than one-third of ...

a sulfated glycosaminoglycan. Heparin combines with antithrombin III in a one to one molar ratio and the resultant complex inhibits factor Xa and thrombin. Another specific control mechanism involves the vitamin K-dependent proteins, protein S and protein C, which combine with each other in molar ...
Prothrombin time (PT) and the associated international normalized ratio (INR) are routinely tested to assess the risk of bleeding or thrombosis and to monitor response to anticoagulant therapy in patients. To measure PT/INR, conventional coagulation testing (CCT) is performed, which is time-consumin...
"For 36 patients with normal international normalised ratio (INR) and activated partial thromboplastin time (aPTT) values 2–6 hours after snakebite, the AUC was 0.97; with a cut-off of 1.4 mg/L, sensitivity was 94% and specificity 96%. "In all but one of 84 patients who developed VICC...
