Citrate plasma, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
This test requires a blood sample. A healthcare professional will draw a sample of your blood, typically from a vein in your arm.
Test Time:
The test results are usually available within a few days, although the exact time may vary depending on the laboratory’s workload.
Test Normal Range:
The normal range for protein S activity can vary between laboratories. Results are reported as a percentage of normal activity.
What is the Test?
The Protein S Activity Test measures the functional activity of protein S in your blood. Protein S is a natural anticoagulant, which means it helps prevent blood clot formation.
Test Procedure:
A healthcare provider will clean the area, usually in your arm, where they will draw the blood. They will then use a needle to collect a sample of your blood into a special tube. A blood sample is delivered to a laboratory for testing. In the laboratory, the sample is tested to determine the functional activity of protein S. The results are reported as a percentage of normal activity.
When to Take the Test:
Assess the risk of excessive blood clotting or thrombosis. Diagnose or monitor conditions such as protein S deficiency, which can increase the risk of blood clots. Evaluate the effectiveness of anticoagulant therapy.
Who Should Take This Test:
The test may be ordered if there is a clinical indication based on your medical history, family history of clotting disorders, or other risk factors.
Precautions for Exceptional Cases (Pregnancy, etc.):
If you are pregnant or have specific medical conditions, discuss them with your healthcare provider before taking the test, as these factors can affect the results and interpretation.
