Which body fluid is NOT typically considered infectious under universal precautions?

The reasoning behind urine not being typically considered infectious under universal precautions is based on the understanding of how bloodborne pathogens are transmitted. Universal precautions are designed to protect against exposure to blood and certain other body fluids that are known to carry infectious diseases. Blood, vaginal secretions, and semen are all considered potentially infectious because they may contain high concentrations of bloodborne pathogens.

Urine, on the other hand, is generally not considered to pose the same level of risk, as it is not typically associated with the transmission of bloodborne pathogens. While urine can carry some pathogens, especially in cases of infection, it is not classified under the same infectious bodily fluids recognized under universal precautions which focus mainly on fluids that pose a greater threat of transmission for diseases like HIV and hepatitis. Therefore, understanding the classification of body fluids in relation to infectious risks is crucial in applying universal precautions effectively.
