Results: Reagents in all of the three forms tested (liquid, 24 h and 14 days) resulted in significant shortening of CTs in comparison to the non-activated plasma CT. Liquids returned more rapid CTs in comparison to dried reagents. Most reagents were more sensitive to heparin in dried, rather than in liquid form. Dried reagents based on kaolin as a surface activator were notably more effective in achieving short CT than others, while dried reagents composed of silica and synthetic phospholipids were the most sensitive to heparin.
Conclusion:Two reagents, namely aPTT-SP and SynthASIL which are both based on synthetic phospholipids and silica, were identified as promising candidates for incorporation into point of care diagnostic device platforms as dried reagents.
