Factor V (F5), DNA Analysis details

What Factor V (F5), DNA Analysis shows

The F5 gene provides instructions for making clotting factor V, a protein that helps your blood form clots. This DNA test looks for Factor V Leiden, a common inherited variant that makes factor V resistant to being switched off by activated protein C, so clotting can continue longer than it should. It is included in pharmacogenomic and clotting risk panels because the variant can affect clot risk with certain hormone medicines, surgery or pregnancy. The result reports whether you carry no, one or two copies of the variant. It reflects a lifelong genetic variant, not a level that changes, and many carriers never have a clot, so it is read alongside your personal and family history.
