Apparatus and method for plasma preparation

摘要

A collection device for plasma preparation for diagnostic assays. The device comprises a spray-dried anticoagulant formulation on the interior surface of the device and a thixotropic polymeric gel. The device is an improvement over commercially available devices which contain liquid anticoagulant formulations, for use in nucleic acid testing that employ amplifications technologies including, but not limited to, polymerase chain reaction (PCR), branched DNA (bDNA) and nucleic acid sequenced based amplification (NASBA).
