Sensitivity and specificity of pocket‐warmer reverse‐transcriptase loop‐mediated isothermal amplification (pwRT‐LAMP) for the 2009 H1N1 influenza A virus. A: Sensitivity of pwRT‐LAMP for the 2009 H1N1 influenza A virus in volumes of 25 µl (upper panel) and 50 µl (lower panel). Culture supernatants containing the 2009 H1N1 influenza A virus whose copy number (106–100) was measured by real‐time RT‐PCR were used as controls. B: Specificity of pwRT‐LAMP for the 2009 H1N1 influenza A virus. 1, Influenza virus H1; 2, H3; 3, H5; 4, 2009 H1N1 virus (strain A/Tokyo/NIID1/2009(H1N1)); 5, H1N1pdm (strain A/Nagano/RC1/2009(H1N1)); 6, Influenza virus B; 7, PIV1; 8, PIV3; 9, RS virus type A; 10, metapneumovirus; 11, SARS corona virus; 12, cellular RNA of human lymphocytes.
