The false positive antibody results could also be eliminated after 5 times dilution with normal human serum. Although the RT-PCR test has become the standard method for the diagnosis of SARS-CoV-2 infection, false-negative rates have been reported. Therefore, the combination of serum IgM/IgG antibody detection, the nucleic acid test, CT scan and clinical features improves the accuracy of COVID-19 diagnosis. Reliability and usefulness of a rapid IgM-IgG antibody test for the diagnosis of SARS-CoV-2 infection: A preliminary report	./cache/cord-290066-umthoftd.txt	./txt/cord-290066-umthoftd.txt
