About this test
Tested after an unprovoked clot, clots at a young age, or a clear family history. Unlike the protein-based thrombophilia tests, the genetic result is unaffected by an acute clot or by anticoagulants, so timing does not matter.
What it measures
- Factor V Leiden (G1691A)
- Prothrombin G20210A
A note on results. A single test is one part of a clinical picture, not a diagnosis. Discuss your report with a qualified doctor, who will read it alongside your history and examination.
