Screening (CRYOcheck LA Check) and confirmatory (CRYOcheck LA Sure) reagents are manufactured to strict tolerances and do not need to be “matched” by specific lot numbers
CRYOcheck™ LA Check™ is a dilute Russell’s Viper Venom Time (dRVVT) reagent intended to screen for the presence of lupus anticoagulant (LA) in citrated human plasma. The reagent contains Russell’s viper venom, phospholipids, and anti-heparin agents. CRYOcheck LA Check can be used in conjunction with CRYOcheck LA Sure™ to confirm the presence of LA.
