Protein C Gene Mutation Screening (Qualitative)

Why This Test Might Be Ordered

Your doctor may recommend this test if you have a family history of blood clots, recurrent venous thromboembolism (blood clots in veins), or unexplained clotting issues. It may also be part of a broader evaluation for inherited thrombophilia.

What to Expect Before the Test

No special preparation is needed. You’ll provide a blood sample, typically drawn from your arm. The test is usually done in a lab setting and results may take several days to weeks depending on the lab.

What the Test Results Mean

Positive results indicate the presence of specific mutations in the Protein C gene that could raise your risk of clotting. Negative results mean no obvious mutations were found in this test. Discuss results with your healthcare provider to understand your personalized risk and next steps.

Common Conditions Linked to This Test

Protein C deficiency or mutations are associated with an increased risk of blood clots, especially in veins (deep vein thrombosis) or arteries (pulmonary embolism). It’s important to manage risk factors like staying active, avoiding long periods of inactivity, and following any prescribed treatments.
