Prothrombin time, activated partial thromboplastin time and dilute Russell's Viper Venom times are not shorter in patients with the prothrombin G20210A mutation, and dilute Russell's Viper Venom time may be longer

We observed an association between longer dRVVT and the prothrombin G20210A mutation in a retrospective observational study. These findings merit further study in large well-characterized clinical cohorts and laboratory research experiments.
