Diagnostica Stago, Inc. Introduces STA® Staclot® DRVV Lupus Anticoagulant Assays

October 7, 2010, Parsippany, NJ — Diagnostica Stago, Inc. is pleased to announce the addition of STA® Staclot® DRVV Screen and STA Staclot DRVV Confirm lupus anticoagulant (LA) assays. These fully automated assays use the diluted Russell’s viper venom method to detect lupus anticoagulants in patient plasma, and each reagent is bar-coded for ease of use on Stago’s STA analyzers.

The STA Staclot DRVV Screen utilizes a low phospholipid reagent, which enhances its sensitivity to the presence of LA, resulting in a prolonged clotting time while the STA Staclot DRVV Confirm utilizes a high phospholipid reagent, which neutralizes LA present in the plasma resulting in a shortened clotting time. The tests are unaffected by contact factor deficiencies, factor VIII and IX deficiencies or other specific inhibitors. The assay is not affected by samples containing therapeutic heparin levels.

"The addition of STA Staclot DRVV Screen and STA Staclot DRVV Confirm assays to our lupus testing product line means that our customers now have a full range of lupus testing assays to meet their needs," explains Bob Bachkosky, Director of Marketing at Diagnostica Stago.

STA Staclot DRVV Screen and STA Staclot DRVV Confirm, when used in conjunction with Staclot LA, fulfill the recommendations for diagnosis of lupus anticoagulants established by the Scientific Subcommittee on Lupus Anticoagulants/Antiphospholipid Antibodies of the International Society on Thrombosis and Haemostasis (ISTH)¹.
