While diagnostic equipment is not PPE per se, they are used together in medical facilities and nursing homes. This is because identifying potential hazards is extremely useful when trying to keep infections at bay. Diagnostic equipment like thermometers, oximeters, and Covid-19 tests can all help identify such hazards. Other non-PPE categories are also closely related and play an important part in personal protection. They include sanitization equipment, hospital-grade disinfectants, table covers, and hand sanitizers.
