Among the detection methods of blood transfusion-related pathogens, which of the following can detect multiple kinds?

Nucleic acid detection method, serological detection method.

1, nucleic acid detection methods (such as PCR): nucleic acid detection methods detect specific gene sequences of pathogens to determine whether they exist. Design some different primers and probes to detect a variety of pathogens.

2. Serological detection method: Serological detection method is to determine the existence of pathogen infection by detecting antibodies in serum. Some serological detection methods can simultaneously detect antibody reactions caused by multiple pathogens, such as ELISA (enzyme-linked immunosorbent assay).
