CRYOcheck™ Weak Lupus Positive Control is intended for use as a positive control in assays for lupus anticoagulant (LA). It contains citrated human plasma collected from donors that have tested positive in accordance with the revised criteria of the SSC Subcommittee for the Standardization of Lupus Anticoagulants. CRYOcheck Weak Lupus Positive Control is a weak positive LA control that challenges an assay's sensitivity to LA, allowing users to be confident that weak LA positive patient samples will be accurately detected.
