The TUD K2 EDTA Gel Plasma Preparation Tube (TUD K2EDTA GEL Tube) is a plastic vacuum tube for the collection of venous blood which upon centrifugation separates undiluted EDTA plasma for use in molecular diagnostic test methods (such as but not limited to PCR - polymerase chain reaction and/or bDNA - branched DNA amplification techniques) or other procedures where an undiluted EDTA plasma specimen is required as determined by the laboratory.
