It is clinically important to be able to detect influenza A/H1N1 virus using a fast, portable, and accurate system that has high specificity and sensitivity. To achieve this goal, it is necessary to develop a highly specific primer set that recognizes only influenza A viral genes and a rapid real-time PCR system that can detect even a single copy of the viral gene. In this study, we developed and validated a novel fluidic chip-type real-time PCR (LabChip real-time PCR) system that is sensitive and specific for the detection of influenza A/H1N1, including the pandemic influenza strain A/H1N1 of 2009. This LabChip real-time PCR system has several remarkable features: (1) It allows rapid quantitative analysis, requiring only 15 min to perform 30 cycles of real-time PCR. (2) It is portable, with a weight of only 5.5 kg. (3) The reaction cost is low, since it uses disposable plastic chips. (4) Its high efficiency is equivalent to that of commercially available tube-type real-time PCR systems. The developed disposable LabChip is an economic, heat-transferable, light-transparent, and easy-to-fabricate polymeric chip compared to conventional silicon- or glass-based labchip. In addition, our LabChip has large surface-to-volume ratios in micro channels that are required for overcoming time consumed for temperature control during real-time PCR. The efficiency of the LabChip real-time PCR system was confirmed using novel primer sets specifically targeted to the hemagglutinin (HA) gene of influenza A/H1N1 and clinical specimens. Eighty-five human clinical swab samples were tested using the LabChip real-time PCR. The results demonstrated 100% sensitivity and specificity, showing 72 positive and 13 negative cases. These results were identical to those from a tube-type real-time PCR system. This indicates that the novel LabChip real-time PCR may be an ultra-fast, quantitative, point-of-care-potential diagnostic tool for influenza A/H1N1 with a high sensitivity and specificity. © 2012 Song et al.

BACKGROUND: NBS LabChip G2-3 is a novel, ultrafast, chip-type portable real-time polymerase chain reaction (PCR) system. We evaluated the clinical usefulness of this system in detecting pulmonary TB and assessed its diagnostic performance compared witha conventional tube-type PCR system. METHODS: A total of 247 sputum samples were collected from patients suspected of having pulmonary TB. After the decontamination process, these samples were examined by fluorescence staining for acid-fast bacilli, cultures with both solid and liquid media, and real-time PCR with the NBS LabChip and a conventional tube-type system. The diagnostic accuracy of the NBS LabChip system and the agreement between the two assays were evaluated. RESULTS: Considering mycobacterial culture results as a gold standard, the overall sensitivity and specificity of the NBS LabChip was 83.8% (95% CI, 73.8%-91.1%) and 94.0% (95% CI, 89.3%-97.1%), respectively. For the detection of TB from the smear-positive samples, the sensitivity and specificity of the NBS LabChip was 96.0% (95% CI, 86.3%-99.5%) and 83.3% (95% CI, 72.3%-95.7%), respectively. For the smear-negative samples, the sensitivity and specificity of the NBS LabChip was 63.3% (95% CI, 43.9%-80.1%) and 95.0% (95% CI, 90.4%-97.8%), respectively. There were no significant differences in the sensitivity and specificity between the NBS LabChip and a conventional tube-type system, although the NBS LabChip shortened the PCR time (27 min for 45 cycles). CONCLUSIONS: The NBS LabChip G2-3 system has potential as an ultrafast, cost-effective diagnostic tool for pulmonary TB with high sensitivity and specificity. © 2014 American College of Chest Physicians.
