Text: Screening test for the factor V Leiden gene mutation and other causes of activated protein C resistance. While factor V Leiden is, by far, the most common genetic cause of aPC resistance, other polymorphisms can produce this condition. aPC resistance can occur due to an elevated factor VIII level, in itself a risk factor for thrombosis.
Methodology: Clot-Based Assay
