Colloidal gold-labeled mouse-antihuman lgM/lgG antibody was manufactured by SAIYA Hebei Biotechnology Co., Ltd. To obtain the well-performance antibody, the antibody was selected for functional test including the positive and negative coincidence rates, minimum test threshold, and accelerated stability. Due to only around 50% positive rate of SARS-CoV-2 nucleic acid test 8, 12 under various condition of sample collection and storage, viral infection regions, RNA extraction methods, the quality of nucleic acid detection kit, and so on, 13 detection of IgM/IgG became a powerful approach for the early diagnosis of COVID-19 and could help identify the patients with negative nucleic acid but with obvious clinical symptoms. Development and clinical application of a rapid IgM-IgG combined antibody test for SARS-CoV-2 infection diagnosis	./cache/cord-341254-xnj6slby.txt	./txt/cord-341254-xnj6slby.txt
