    Intended Use

    The Vital Scientific APTT is an in-vitro diagnostic reagent intended for use in a manual method in a clinical laboratory for the performance of Activated Partial Thromboplastin Time (APTT) testing for the detection of coagulation abnormalities in the intrinsic pathway.

    Device Description

    The APTT reagent is intended for use in determining activated partial thromboplastin time (APTT) and coagulation factor assays that are based on a modified APTT. The capacity of blood to form a fibrin clot by way of the intrinsic homeostatic pathway requires coagulation factors XII, XI, IX, VIII, platelet lipids and calcium. The assay is performed by the addition of a suspension of rabbit brain cephalin with a surface activator.
