General additional information
The Prothrombin G20210A and Factor V Leiden screen for Thrombophilia forms part of the wider 'Hereditary Thrombophilia Screen' and are often requested together. However, the genetic testing is performed in a separate Laboratory and as a result, a separate report will be issued with the Prothrombin G20210A and Factor V Leiden results.
Citrated anticoagulated venous blood or 150µl DNA may be sent instead of an EDTA specimen.
