The video tutorial explains two main viral testing techniques: PCR and immunoassays. PCR testing targets the virus's genetic material to diagnose current infections by amplifying genetic information. Immunoassays detect antibodies to determine past infections and potential immunity. The video also highlights advancements in testing technology and their critical role in managing viral outbreaks.
