Protein C test measures the level of protein C in your blood. Protein C helps your blood clot normally.
To help evaluate inappropriate blood clot formation (thrombotic episode or thromboembolism); to determine whether you may have a protein C deficiency.
The normal protein C level in a healthy adult is approximately 65-135 IU/dL. For a healthy term infant, the average value is 40 IU/dL, which will increase as the child ages, to approximately 60 IU/dL; the adult range typically is not reached until after puberty. Activated protein C is found at levels approximately 2000 times lower than this.
