Activated partial thromboplastin time (aPTT) in Platelet poor plasma by Coagulation assay -- after addition of protein C activator/Activated partial thromboplastin time (aPTT)

aPTTprotein C activator/aPTT PPP

Definition

  • The protein C pathway the patient's protein C is activated by agkistrodon contortrix (Protac[TM]). Then, an aPTT or DVVR-based coagulation is started. These tests should screen the protein C pathway covering protein C defects, protein S defects and Factor V Leiden mutations.
