To the Editor,The recent paper entitled “Development of a specific and rapid diagnostic method for detecting influenza A (H1N1) pdm09 virus infection using immunochromatographic assay” by Ji et al [1] is very interesting. Ji et al [1] concluded that “the proposed method can be easily used for rapid and specific detection of the pdm09 infection.” To develop a new diagnostic test for detecting influenza A (H1N1) pdm09 virus infection would be useful. The problem with the present technique is the low sensitivity. Although it has 100% specificity, the test cannot be used as a good screening tool due to poor sensitivity [2]. A rapid test for detecting influenza A (H1N1) pdm09 virus should help screen suspected cases of the disease. The cost of the new test is a very interesting issue. Whether or not this new test is cost-effective requires further clarification.
