Serine Protease Inhibitor 1 (SERPIN1) Gene Full Mutation Analysis via Whole Blood DNA Sequencing

What This Test Measures

The test analyzes DNA from your whole blood to identify full mutations in the SERPIN1 gene. This gene produces serine protease inhibitor 1 (also called antithrombin), a protein that helps regulate blood clotting. Mutations in this gene may lead to conditions like hereditary thrombophilia or other bleeding disorders.

Why It Might Be Ordered

Your healthcare provider may recommend this test if you have a family history of blood clotting disorders, unexplained bleeding, or symptoms like easy bruising, prolonged bleeding from cuts, or recurrent blood clots.

Sample Collection and Process

A blood sample is taken from you, typically from a vein in your arm. The DNA is extracted from the blood cells and sequenced to detect any full mutations in the SERPIN1 gene. This process is usually done in a lab setting and may take several days to complete.

What the Results Mean

Results will indicate whether full mutations in the SERPIN1 gene are present. If mutations are found, they may suggest an increased risk for blood clotting or bleeding disorders. However, not all mutations cause symptoms, and some may be harmless variants.
