What does Activated protein C do?

Protein C, also known as autoprothrombin IIA and blood coagulation factor XIX, is a zymogen, the activated form of which plays an important role in regulating anticoagulation, inflammation, and cell death and maintaining the permeability of blood vessel walls in humans and other animals.

What does a positive activated protein C resistance mean?

Specialty. Hematology. Activated protein C resistance (APCR) is a hypercoagulability (an increased tendency of the blood to clot) characterized by a lack of a response to activated protein C (APC), which normally helps prevent blood from clotting excessively.

What causes elevated protein C?

Agewall et al suggested an increase in hepatic synthesis of protein C due to increased hepatic insulin resistance. Increased levels have been reported in patients with diabetes, hypertriglyceridaemia, and nephrotic syndrome, with the use of anabolic steroids, oral contraceptives, and alcohol, and with increasing age.

What is a normal protein C level?

A normal level of protein C in the blood is between 70% and 150%. Lower-than-normal readings may mean that you have a protein C deficiency. A lower-than-normal level of protein C may be caused by: Blood-thinning medicines, such as warfarin.

Which protein helps in blood clotting?

Fibrinogen… A specialized protein or clotting factor found in blood. When a blood vessel is injured, thrombin, another clotting factor, is activated and changes fibrinogen to fibrin.

What is the normal range for activated protein C resistance?

Reference Range The normal reference value for the activated protein C resistance (APCR) ratio is greater than 2.1.

Is protein C deficiency a blood disorder?

Protein C deficiency is a disorder that increases the risk of developing abnormal blood clots; the condition can be mild or severe. Individuals with mild protein C deficiency are at risk of a type of blood clot known as a deep vein thrombosis (DVT).

How do I lower my protein C?

You may not be able to prevent a protein C deficiency, but you can take steps to reduce your risk for blood clots:

  1. Exercise regularly.
  2. Take all medications prescribed by your doctor.
  3. Wear socks called “compression stockings” if your doctor prescribes them.
  4. Avoid standing or sitting for prolonged periods of time.

What does protein C measure?

Protein C is a plasma anticoagulant factor required for maintenance of hemostatic balance. Protein C is synthesized in the liver and measurement of protein C activity aids in the diagnosis of thrombotic disorders and liver disease.

What is the difference between protein C and protein S deficiency?

Congenital C and S proteins are natural substances in the blood that help prevent blood clots. Protein C deficiency occurs in approximately 1 of every 200 to 500 people, whereas protein S deficiency occurs in approximately 1 of every 500 individuals.1,2 Deficiency may be determined from a blood sample.

What is the function of protein C and S?

Protein C and protein S are two proteins in the blood that help regulate blood clot formation. Two separate tests for these proteins are often performed together as part of the investigation of a possible excessive clotting disorder.
