What is the Role of Laboratory Tests in Epidemiological Diagnosis?
Laboratory tests are indispensable in epidemiological diagnosis due to their ability to provide definitive evidence of disease presence. They include: 1. Molecular Tests: Such as PCR for detecting infectious agents. 2. Serological Tests: For identifying antibodies or antigens. 3. Culture Methods: For isolating and identifying pathogens. 4. Imaging Techniques: Such as X-rays and MRI, which can reveal structural abnormalities.
