LOD of detection of avian influenza A (H7N9). The RNA extraction of avian influenza (H7N9) was serially diluted in tenfold increments and detected using this microarray and influenza A virus Nucleic Acid Detection Kits (PCR-fluorescent probe) (Shenzhen Puruikang Biotech Co., Ltd.). The microarray possessed a tenfold higher LOD to avian influenza A (H7N9) than the real-time RT-PCR method
