In epidemiology, various types of samples may be transported, including:
1. Blood Samples: Used for serological tests, genetic analysis, and detection of blood-borne pathogens. 2. Urine Samples: Often used for screening and monitoring infections and metabolic diseases. 3. Tissue Samples: Collected for histopathological analysis to study disease at the cellular level. 4. Swabs: Used to collect respiratory, oral, or rectal samples for detecting infectious agents. 5. Environmental Samples: Such as water, soil, and air samples, used to identify environmental health hazards.
