Coamplified positive control detects inhibition of polymerase chain reactions

Abstract excerpt

Polymerase chain reactions (PCR) may fail to react because the substrate DNA is absent (true negative) or because of inhibition of specific amplification (false negative). The use of positive controls can increase confidence in negative PCR results by ruling out failure due to inhibition as a cause of the lack of amplification products. This report describes the construction and application of coamplified...
