Screening and Diagnosis: NATs are used for screening blood donations to prevent transfusion-transmitted infections and for diagnosing diseases such as COVID-19, HIV, and Hepatitis. Outbreak Investigation: During outbreaks, NATs help identify the causative pathogen, enabling targeted control measures. Surveillance: NATs are used in epidemiological studies to monitor the prevalence and spread of infectious diseases.
