Initial Assessment
Doctors start with a detailed history and physical examination to identify potential exposure risks. They ask about recent travel, food intake, and any known outbreaks. These initial clues help guide further testing decisions.
Laboratory Tests
Stool samples are commonly tested to identify pathogens like bacteria, viruses, or parasites. Tests may include culture, antigen detection, or PCR to pinpoint the infectious agent. These tests are essential for accurate diagnosis and treatment planning.
