Many non-routine tests and applications which require the collection of blood or other body fluids also require the use of special anti-coagulant or proteinase inhibitor cocktails to preserve the integrity of the sample.
Good examples of such tests include the measurements of Fibrinopeptide-A (FPA), Prothrombin Fragment 1o2 (F1o2), Fibrinogen Degradation Products (FDP) and the Thrombin/Antithrombin III complex (TAT), all of which are influenced by persistent protease activity in blood or plasma samples.
The SCAT (Sample Collection/Anticoagulant Tubes) series of collection tubes produced by Haematologic Technologies were developed specifically to minimise in vitro artifact by rapidly quenching unwanted protease activity. SCAT tubes are formulated to yield a reproducible concentration of inhibitors with rapid dissolution properties. The tubes are evacuated and stoppered under controlled conditions so that the tubes will automatically fill to the proper volume.
Haemtech will custom make tubes to the user's specifications in small or large batches.
