Serological antibody screening tests for COVID-19 currently include ELISA, LFIA, and CLIA methods, with the ELISA technique being the most commonly used.
It is important to note that various serological tests are cost-effective, convenient, and more efficient for commercial applications than the RT-PCR detection for COVID-19. Moreover, developing effective and reliable serological detection methods plays a vital role in monitoring the abundance and neutralization efficiency of antibodies in infected patients, evaluating and predicting the severity of symptoms of patients, and quantifying the quality of immune response to new vaccines.
