Protein C Functional Blood Test

The Protein C Functional Blood Test is used to help investigate a possible clotting disorder.


Test Code: 117705

CPT Code: 85303

Also Known As: Functional Protein C; Protein C, Functional, Plasma; Protein C, Functional Blood Test

Methodology:

A specific enzyme extracted from the venom of Agkistrodon c. contortrix is used to activate PC in the patient sample. All other factors required for normal aPTT are supplied in the reagent. The activated protein C inhibits factors V and VIII in the reagent and the resultant prolongation of the aPTT-based clotting time is proportional to plasma PC activity.

Preparation:

No fasting required. Ideally, patients should not be on anticoagulant therapy. Avoid warfarin therapy 2 weeks before blood draw. Avoid heparin, direct Xa, and thrombin inhibitor therapies for 3 days before blood draw. Check with physician before stopping any medications.

Test Results:

5-7 days. May take longer based on weather, holiday or lab delays.
