CRYOCHECK™ LA CHECK™

Cat Num. ConditioningPackage size  
CHK-1025 x 1,0 mL300
A dilute Russell’s Viper Venom Time (dRVVT) reagent intended to screen for the presence of lupus anticoagulants (LA) in citrated human plasma.
cryocheck LA Check contains Russell’s viper venom, phospholipids, antiheparin agents, calcium, buffers stabilizers, Sodium azide, and green dye.
Information
Recent guidelines and recommendations for laboratory detection of lupus anticoagulants: The International Society on Haemostasis and Thrombosis (ISTH) and the British Committee for Standards in Haematology (BCSH) have recently updated their lupus anticoagulant (LA) detection guidelines. The Clinical and Laboratory Standards Institute (CLSI) subsequently will publish its first LA guideline. General agreement exists on issues such as sample preparation, the use of dilute Russell viper venom time (dRVVT) in diagnostic repertoires, the use of normalized ratios, calculations to demonstrate phospholipid dependence, calculations to demonstrate inhibition, and interpretive reporting.
Characteristics
  • Stable up to 48 hours when stored at 2...8° C
  • If necessary, the plasma can be refrozen once
  • Adaptable on hemostasis analyzers (protocols available on request)
