Haematex R&D has resulted in a patented method for procoagulant phospholipid (XACT test) which detects microparticles and platelet activation. This low cost method for detecting hypercoagulability has been licensed to a major diagnostic company. We have developed lupus anticoagulant sensitive and LA resistant APTT coagulation reagents in liquid and powder forms and dRVVT in powder form for preparation of freeze dried or frozen reagents. We can supply phospholipids (both native and synthetic), contact activators and equine collagen for platelet function testing. We are keen to engage in practical R&D with any group seeking to develop new methods, reagents or test kits.


Non-Activated Partial Thromboplastin Time


This kit is intended for use in the European Pharmacopeia (EP) method for the detection of activated coagulation factors in theraputic products.

1. Liquid NAPTT reagent containing sythetic phospholipid blend (10ml)
2. Sample diluent (EP buffer) 0.09sodium chloride, 0.06M tris at pH 7.5 (10ml)
3. Positive control 100x concentrate containing 0.04u/ml factor Xa in a stabilizing base (1ml)
4. Normal freeze dried plasma (PNP) to be reconstituted with 5ml water.
