Frozen Format LA Screen (FFLAS) and Frozen Format LA Confirm (FFLAC) are simplified DRVVT reagents for detection of Lupus Anticoagulants (LA) in one-stage clotting tests. Frozen Format LA Confirm is a phospholipid-rich DRVVT reagent for the specific correction of Lupus Anticoagulants. This product is for in-vitro diagnostic use only.

Frozen Format LA Screen (FFLAS) and Frozen Format LA Confirm (FFLAC) are simplified DRVVT reagents for detection of Lupus Anticoagulants (LA) in one-stage clotting tests. Frozen Format LA Screen is a simplified DRVVT reagent to screen for the presence of Lupus Anticoagulants. This product is for in-vitro diagnostic use only.

Frozen Format LA Screen (FFLAS) and Frozen Format LA Confirm (FFLAC) are simplified DRVVT reagents for detection of Lupus Anticoagulants (LA) in one-stage clotting tests.

The HemosIL dRVVT Screen and HemosIL dRVVT Confirm assays are qualitative in-vitro diagnostic products to aid in the detection of lupus anticoagulants in human citrated plasma by the diluted Russell's Viper Venom method, on the ACL TOP® Family. The HemosIL dRVVT Screen and HemosIL dRVVT Confirm assays are intended to evaluate patients who have unexplained prolonged APTT test results The HemosIL dRVVT Screen and HemosIL dRVVT Confirm assays should be used in parallel as an integrated test for Lupus Anticoagulant detection.

DRVVT Screen and dRVVT Confirm are improved dRVVT reagents, intended to simplify and standardize the detection of Lupus Anticoagulant (LA) disorder in clinical chemistry evaluations. DRVVT Screen is poor in phospholipid, making it sensitive to LA. The additional amount of phospholipid in dRVVT Confirm neutralizes LA to give shorter clotting times. Russell's viper venom, in the presence of calcium, directly activates factor X (in a test sample). DRVVT Screen and dRVVT Confirm are therefore unaffected by contact factor abnormalities, factor VII, VIII and IX deficiencies, or inhibitors. As a result, dRVVT Screen and dRVVT Confirm are more specific tests for the evaluation of LA than APTT.

LupoTek Detectin VL and Correctin VL test kits are qualitative tests intended to aid in the detection of lupus anticoagulants (LA) in citrated human plasma by the dilute Russell's viper venom method in professional clinical laboratories. PlasmaCon LA is intended for use as an LA positive, abnormal quality control plasma to monitor the performance of diagnostic assays, performed in professional clinical laboratories, for the presence of lupus anticoagulants in citrated plasma.

LupoTek Detectin VL and LupoTek Correctin VL use Vipera lebetina venom rather than Vipera russelli (Russell's Viper) venom in the dRVVT assay for lupus anticoagulant. Vipera lebetina venom, like Russell's viper venom, will directly activate Factor X without requiring Factor VII. The activated Factor X in conjunction with Factors V, II, calcium ions and phospholipid will generate thrombin which converts fibrinogen to fibrin, producing a clot in the test system. LupoTek Detectin VL, the low phospholipid reagent, is designed as the screening reagent to detect a prolongation of the clotting time. LupoTek Correctin VL is the high phospholipid reagent that neutralizes the LA and corrects the clotting time to normal, confirming the presence of a Lupus Anticoagulant. PlasmaCon LA is a lyophilized Lupus Anticoagulant (LA) positive plasma suitable for use as a quality control plasma for in vitro diagnostic assays in the clinical coagulation laboratory sensitive for the presence of LA

The STA®-Staclot® dRVV Screen and STA®-Staclot® dRVV Confirm kits are intended for the detection of lupus anticoagulants (LA) in plasma by the dilute Russell's viper venom method (1) performed with analyzers of the STA® line suitable to these reagents.

The in vitro diagnostic device presented in this 510K submission, STA® -Staclote dRVV Screen and STA® -Staclot® dRVV Confirm, is substantially equivalent to the IL Test LAC Screen and Confirm manufactured by Instrumentation Laboratories.

CryovCheck™ LA Sure™ dilute Russell's Viper Venom Test (dRVVT) is a high concentration phospholipid reagent intended for use in a confirmatory test to verify the presence of lupus anticoagulants (LA) in human plasma. Once LA is suspected by a prolonged result with the Cryov Check™ LA Check™ screening (low concentration phospholipid) reagent, LA Sure may then be used concomitantly to establish a ratio (LA Check/LA Sure) useful in discriminating between LA positive and LA negative specimens.

Cryo Check™ LA Sure™ dilute Russell's Viper Venom Test (dRVVT) is a high concentration phospholipid reagent.

Cryo✓Check™ LA Check™ dilute Russell's Viper Venom Test (dRVVT) reagent is a low concentration phospholipid reagent intended for use as a screening test for the presence of lupus anticoagulants (LA). It may be used in conjunction with CryovCheck™ LA Sure™ (a high concentration phospholipid confirmatory reagent) to establish a ratio (LA Check/LA Sure) useful in discriminating between LA positive and LA negative specimens.

IL Test™ LAC Screen and IL Test™ LAC Confirm are in vitro diagnostic products for the detection of lupus anticoagulants (a type of phospholipid interfering antibody) in human citrated plasma on IL Coagulation Systems. These tests are indicated for use with patients who have prolonged APTT test of undetermined origin. This 510(k) is intended to extend the use of these reagents onto another member in the IL family of coagulation analyzers, the ACL Futura (K951891).
