Yet, due to the reaction temperature during LAMP (approximately 70 °C), aerosols are inevitably produced, which results in a high rate of false-positive results. Detection specificity, primer design, and temperature control also need to be optimized for LAMP. Moreover, chip designs that implemen...
Studies have investigated the differences between the rapid COVID-19 test kit versus the CLIA quantitative antibody test. The results differed greatly—8.8% of subjects tested positive using the rapid test kit (with 92% sensitivity, 97% specificity) compared with 0.9% using the CLIA quantitative I...
In successive paired serum samples, a decrease of IgM titer or an increase (more than four-fold) of IgG titer, or both can characterize a recent infection [22]. IgM usually disappears within 30 to 168 days after infection, while IgG can persist for years [39]....
