Understanding Viral Testing Techniques

The video tutorial explains two main viral testing techniques: PCR and immunoassays. PCR testing identifies current infections by amplifying the virus's genetic material, while immunoassays detect past infections by identifying virus-specific antibodies. The video details the processes, applications, and advancements in these testing methods, highlighting their critical role in diagnosing and managing viral outbreaks.
