Liquid compontent kits containing phospholipid extract and silica contact activator. Sensitive to heparin as well as factors and insensitive to lupus anticoagulant.

Medirox APTT liquid reagent is used for in vitro determination of the Activated Partial Thromboplastin Time (APTT).

APTT is measured to obtain a global evaluation of the intrinsic pathway and for monitoring heparin anticoagulant therapy. The Medirox APTT reagent has been designed to provide an extra long reaction time in order to obtain a high resolution for clearest interpretation of results.
