In various embodiments, disclosed herein are assays for measuring thrombin generated (TG) in a blood sample, comprising: incubating the blood sample with TF, FIXa, and CaCl2; and measuring TG in the blood sample. Also disclosed herein are assays for determining a bleeding risk in a subject, comprising obtaining a blood sample from the subject; adding to the blood sample TF and/or FIXa; determining the amount of coagulation factor VIII (FVIII:C) in the blood sample; and determining (a) a mild bleeding risk in the subject if the amount of FVIII:C in the sample is >5 IU/dL, (b) a moderate bleeding risk in the subject if the amount of FVIII:C in the sample is 1-5 IU/dL, and (c) a severe bleeding risk in the subject if the amount of FVIII:C in the subject is <1 IU/dL.
在各种实施方案中,本文公开了用于测量血液样本中凝血酶生成量(TG)的检测方法,包括:用 TF、FIXa 和
CaCl2 培养血液样本;以及测量血液样本中的 TG。本文还公开了用于确定受试者出血风险的检测方法,包括:获取受试者的血样;向血样中添加 TF 和/或 FIXa;确定血样中
凝血因子 VIII (FVIII. C) 的含量;以及测定血样中凝血酶原 (TG) 的含量:C);如果样本中 FVIII:C 的量大于 5 IU/dL,则确定(a)受试者有轻度出血风险;如果样本中 FVIII:C 的量为 1-5 IU/dL,则确定(b)受试者有中度出血风险;如果受试者中 FVIII:C 的量小于 1 IU/dL,则确定(c)受试者有严重出血风险。
