Abstract
We developed a rapid and simple magnetic chemiluminescence enzyme immunoassay on the Real Express‐6 analyzer, which could simultaneously detect immunoglobulin G and immunoglobulin M antibodies against SARS‐CoV‐2 virus in human blood within 18 min, and which could be used to detect clinical studies to verify its clinical efficacy. We selected blood samples from 185 COVID‐19 patients confirmed by polymerase chain reaction and 271 negative patients to determine the clinical detection sensitivity, specificity, stability, and precision of this method. Meanwhile, we also surveyed the dynamic variance of viral antibodies during SARS‐CoV‐2 infection. This rapid immunoassay test has huge potential benefits for rapid screening of SARS‐CoV‐2 infection and may help clinical drug and vaccine development.
