PT/INR Correction with Mixing
Correction of PT/INR with Mixing
If the PT/INR is initially elevated but becomes normal when control plasma is added, this suggests that there is factor deficiency as the cause of coagulopathy.
This occurs commonly in the setting of warfarin or vitamin K deficiency, however may occur in the context of deficiencies affecting multiple pathways.
Causes of PT/INR Correction with Mixing
- Warfarin
- Vitamin K deficiency
- Congenital factor deficiency
- Disseminated intravascular intracoagulation
- Liver failure
