Protein C blood test
Protein C Blood Test
Protein C is a compound in the blood that helps the body prevent excessive bleeding. The Protein C level in the blood can be tested to determine if a person has an inherited or acquired bleeding disorder. In this article, we discuss what a Protein C blood test is and its purposes, how to prepare for the test, the procedure of the test, types of test, risks of the test, and when the test is necessary.
Purpose of a Protein C Test
The primary purpose of a Protein C test is to identify if a person has an inherited or acquired coagulation disorder. This disorder, otherwise known as a bleeding disorder, occurs when the blood’s clotting system is not functioning properly, leading to excessive bleeding. It can be caused by a decrease in the level of Protein C or an inherited deficiency in the protein. If the test shows a low level of Protein C, it means that the person is at risk for a bleeding disorder.
How to Prepare for a Protein C Blood Test
It is best to consult a healthcare professional before getting a Protein C test. The certain preparations for the test may vary depending on your particular doctor’s recommendations. Generally, you will need to fast or not eat or drink for up to eight hours prior to the blood draw, which is a typical requirement for most blood tests. Other preparations may not be necessary.
Procedure of a Protein C Blood Test
Like most blood tests, a Protein C blood test is relatively quick and painless. During the test, a healthcare professional will take a sample of your blood, usually from a vein in the arm. The sample is then sent to a laboratory to be examined. Results of the test are typically available within a few days.
Types of Protein C Blood Test
- Protein C Activity test: This test measures the activity of the protein, which is how fast it can break down clot-forming cells.
- Protein C Antigen test: This test measures the amount of Protein C in the blood as well as its activity.
- Protein C Deficiency test: This test measures the amount of Protein C in the blood. It is usually combined with the other two tests to provide a more complete evaluation of the status of Protein C.
Risks of a Protein C Test
The risks associated with a Protein C test are very minimal. The most common side effects are discomfort in the vein from which the blood sample was taken and bruising at the site. Rarely, an infection can develop at the puncture site.
Why is a Protein C Test Necessary?
A Protein C test is an important tool for diagnosing and managing a bleeding disorder. It can be used to identify if a person is at risk for excessive bleeding due to a genetic deficiency or acquired disorder. It can also be used to monitor the effect of anticoagulant medications, such as warfarin, on the blood. It is important to note that other tests, such as a prothrombin time (PT) or international normalized ratio (INR) test, may be necessary to confirm or complete the diagnosis.
When is a Protein C Test Necessary?
A Protein C test may be recommended when a person is experiencing symptoms of a bleeding disorder such as prolonged bleeding from cuts. It may also be suggested when a person is on anticoagulant medication or if they have a family history of bleeding disorders. In some cases, a Protein C test may be used in conjunction with other tests to make a diagnosis.
