NIPT, CF testing. Patients with a single point mutation in the gene coding for factor V produce a mutated factor V (called Factor V Leiden) that is resistant to inactivation by APC, resulting in increased thrombin production and a hypercoagulable state. BJOG. However, substantial inter- and intra-observer discrepancies occur even when the standard histologic criterion is applied, which has lead to the controversy surrounding this disorder. Early pregnancy loss is defined as the termination of pregnancy before 20 weeks' gestation or with a fetal weight of < 500 g.
