Fig. 5From: Thrombin generation capacity is enhanced by low antithrombin activity and depends on the activity of the related coagulation factorsEffect of changes in coagulation factor activity on thrombin generation. This test is conducted at 30% and 50% AT activity. The adjustment method for each sample is as shown in the table above. Relative Values (%) = 100 × Parameters for each sample / The peak height value of the sample with PT 100%. A: Effect of changes in coagulation factor activity on thrombin generation at 30% AT activities. B: Effect of changes in coagulation factor activity on thrombin generation at 50% AT activities. PT% values 40% and 33% samples required the addition of an AT concentrate since it is not possible to mix and adjust the three samples while keeping the AT activity at 50%. PT% values 40% and 33% samples were adjusted by adding a small amount of recombinant AT concentrate and titrating to 50% AT. AT: antithrombin, PT: prothrombin time.Back to article page
