Activated Protein C - Resistance (APCR)

Protein - C is a component found in the blood and it physiologically functions as an Anticoagulant. This test helps to detect the Protein-C deficiency and diagnosing the hemostatic disorder and coagulation disorder and thrombosis.

Activated Protein C - Resistance (APCR):


Activated protein-C, also called Auto-prothrombin-IIA and blood coagulation factor XIX, is a zymogen, the activated form of which plays an important role in regulating anti-coagulation, inflammation cell death and maintaining the permeability of blood vessel walls in humans. Activated protein-C exerts its anticoagulant activity primarily through the inactivation of coagulation factors V-a and VIII-a, which are required for factor-X activation and thrombin formation for the clot. Hence this test Activated protein-C is a part of the evaluation of patients with coagulation disorders and identifies patients who are deficient in protein-C and/or S. The importance of this test is that the deficiency of activated protein-C would result in a risk of clot formation since there is decreased or no inhibitory feedback on coagulation cascade by protein-C. Some causes for deficiency of Activated protein-C are vitamin-k deficiency, warfarin therapy, severe liver diseases, disseminated intravascular coagulation (DIC), severe bacterial infections in the young, and some chemotherapy drugs. Symptoms of Activated protein-C deficiency are deep vein thrombosis (DVTs) in leg veins causing pain, discoloration and swelling, pulmonary embolism that leads to chest pain, fever, dizziness, coughing, and shortness of breath, and in newborn babies a condition called neonatal purpura.

Elevated levels of Activated protein-C are seen in conditions like increased hepatic insulin resistance in patients with diabetes and hypertriglyceridemia, nephrotic syndrome, with use of anabolic steroids, oral contraceptives, alcohol, and with increasing age. But there is no clinical significance, as they are not associated with any major medical problems as of now till date.
