A. Altes et al., ACTIVATED PROTEIN-C RESISTANCE ASSAY WHEN APPLIED IN THE GENERAL-POPULATION, American journal of obstetrics and gynecology, 176(2), 1997, pp. 358-359
We estimated the predictive values of activated protein C resistance i
n the diagnosis of women who are carriers of factor V Leiden. When the
prevalence of factor V Leiden is 2%, the positive predictive value is
44% and the cost of preventing one thromboembolic death is $44,180,00
0. Thus the activated protein C resistance assay is not cost-effective
in ruling out factor V Leiden in this population.
