Description
Free Protein S
Sample Type:Plasma
Tests Included:
Measurement of free protein S in the blood.
Sample Required:
Blood sample
Test Time:
Results are typically available within a few days.
Test Range Values:
The reference range for free protein S varies but typically falls within 60-130% of total protein S.
What is the test?
Free protein S is a protein that plays a role in the body’s blood clotting process. This test measures the amount of unbound (free) protein S in the blood, which can help assess the risk of blood clotting disorders.
Test Procedure:
A blood sample is drawn from a vein, and the concentration of free protein S is measured in the laboratory.
When to take the test:
This test is often performed to investigate clotting disorders or to assess the risk of excessive bleeding or blood clots.
Who should take the test:
Individuals with a history of blood clots, those with a family history of clotting disorders, or those experiencing abnormal bleeding might be recommended to take this test.
Precautions for exceptional cases (pregnancy, etc.):
Pregnancy can affect protein S levels, and therefore, pregnant individuals should inform their healthcare provider about their pregnancy status.
Frequently Asked Questions (FAQs) for Free Protein S Test:
Q1: Can medications affect free protein S levels?
A: Yes, certain medications, especially anticoagulants, can influence protein S levels. Before the test, let your doctor know about all the medications you use.
Q2: How does free protein S differ from total protein S?
A: Free protein S represents the active, unbound portion, while total protein S includes both free and bound forms. Free protein S levels are more indicative of clotting risk.
Q3: What do low levels of free protein S indicate?
A: Low free protein S levels can increase the risk of excessive blood clotting, potentially leading to conditions like deep vein thrombosis or pulmonary embolism.
Q4: Is this test used for routine check-ups?
A: It’s not typically part of routine check-ups. However, it might be recommended for individuals with known clotting disorders or a family history of such conditions.
Q5: Can lifestyle changes impact free protein S levels?
A: While lifestyle changes might indirectly affect clotting risks, they usually don’t directly impact free protein S levels. However, maintaining a healthy lifestyle can support overall cardiovascular health.
