The Effect of 3.2% and 3.8% Sodium Citrate on Specialized Coagulation Tests

His DRVVT, which was normal at admission, was elevated at 11 months and 23 months, consistent with the presence of lupus anticoagulant; this normalized 3.5 years after admission.

The laboratory and the new oral anticoagulants

"Study after study has shown that the dPT test is required to find lupus- anticoagulant patients that the other tests (e.g., dRVVT and lupus sensitive aPTT test) do not find.

Coag tests get tweaked

LA was studied in two coagulation systems, a dilute sensitized activated partial thromboplastin time (aPTT) and a dilute Russell's viper venom time (dRVVT), followed by confirm test, using reagents and instrumentation by Hemoliance Instrumentation Laboratory, Lexington, MA, USA.
