Test ID: DRVI2    
Dilute Russell Viper Venom Time (DRVVT) Mix Ratio, Plasma

Method Description Describes how the test is performed and provides a method-specific reference

The dilute Russell viper venom time (DRVVT) mix assay is performed on the Instrumentation Laboratory ACL TOP. Patient plasma is mixed in a 1:1 ratio with normal pooled plasma and incubated for a specified time, then combined with a DRVVT screening reagent containing Russell's viper venom, phospholipids, heparin neutralizing agents, calcium, buffers, stabilizers, and sodium azide to trigger the coagulation process. Subsequently, the time to clot formation is measured optically using a wavelength of 671 nm.

 

The patient DRVVT Mix clotting time is normalized by dividing the patient result by the mean DRVVT screening clotting time of normal pooled plasma to yield a ratio.(Package insert: CRYOcheck LA Check, PrecisionBioLogic, Inc., Dartmouth, NS, Insert I-021 Rev. 11)
