Description
VACUETTE® CTAD tubes contain buffered citrate solutions, theophylline, adenosine and dipyridamole. As dipyridamole is extremely sensitive to light, the tubes are wrapped in white plastic film.
The additive trisodium citrate contained in the tube prevents blood coagulation by binding Ca-ions.
VACUETTE® Coagulation Tubes are also known as “sandwich” tubes due to their double-wall-technology. The inner tube is made of PP (polypropylene) and prevents the evaporation of liquid. The outer tube is made of PET (polyethylene terephthalate) and guarantees a correct draw volume.
With the VACUETTE® Coagulation Tubes, underfilling must be avoided for valid test results. Therefore, always, but especially when using a (safety) wing needle, use a Discard tube. This helps to avoid underfilling of the coagulation tube due to the air contained in the tubing.
