<bold>Objective</bold>: The contamination of polymerase chain reaction (PCR) samples in molecular diagnostic laboratories can cause serious consequences. Internal quality control efforts are often inadequate, especially in clinical next-generation sequencing (NGS) laboratories.
<bold>Methods</bold>: In this study, we retrospectively investigated an incidence of PCR contamination and its decontamination process in a clinical laboratory. We performed a series of measures for decontamination. Taqman fluorescence quantification was carried out to determine the presence of contaminating DNA. SYBR-Green PCR was conducted to evaluate the effect of chlorine disinfectant on NGS library preparation.
<bold>Results</bold>: Through a series of elimination measures undertaken over 8 weeks, the decontamination process was verified as reliable. Almost no contamination was detected. Chlorine disinfectant should be forbidden in Illumina NGS laboratories because it may cause the failure of library preparation.
<bold>Conclusion</bold>: Our prevention and decontamination strategies could effectively eliminate PCR amplicons. Chlorine disinfectants should not be used in Illumina NGS laboratories.
