Direct measures of the concentration of unfractionated heparin in the blood are at- tractive because these assays are not affected by many of the bi- ologic variables that interfere with the aPTT and may be suitable for automation. However, currently available unfractionated he- parin assays are ...
A test that evaluates the clotting factors of the intrinsic pathway—except VII and XIII—by measuring the time required to form a fibrin clot. aPTT is used to screen for bleeding tendencies and to monitor heparin therapy; it is increased in coagulation factor deficiencies (factors V, VIII, IX...
Problems with the sample, including an insufficient sample, clotted blood in the sample and heparin contamination of the sample. The presence of a non-specific inhibitor, such as LA (the lupus anticoagulant) Inherited or non-inherited factor deficiencies The presence of a specific inhibitor (...

blood method and sheep plasma method in the potency result,and its FL was lower than the rabbit blood method's.The results demonstrated that coagulometer-APTT method is simple,objective,accurate,reproducible,precise and applying to different in...
The timeit takes for the blood to clot is then measured using a coagulation analyzer. The aPTT assay is used in various clinical settings, including the evaluation of bleeding disorders, monitoring of heparin therapy, and assessment of coagulation factor deficiencies. It provides valuable information ...
Plasma heparin concentration by anti-factor Xa assay was performed on the blood samples obtained after heparin initiation. Heparin dosage adjustment decisions were evaluated by determining the agreement of each aPTT test result with the corresponding plasma heparin concentration. An overall level of ...
