Coagulation factor VIII
F8proteinFactor VIII elevation reflects a pro-coagulative state and augments the intrinsic tenase complex, increasing thrombin generation risk.
Pathway placement
Cascade stepCoagulation & thrombus formation
Confidencemedium
RationaleIntrinsic pathway procoagulant cofactor; elevated in hypercoagulable states and thrombotic risk.
