Will I get infected if nurses don't change gloves when drawing blood?

In general, whether or not infection occurs when a nurse draws blood without changing gloves mainly depends on the specific circumstances. If during the blood draw the nurse's hands did not directly contact the needle or the patient's blood, infection typically will not occur. However, if gloves are not changed between patients or between clean and contaminated areas, there may be a risk of infection.

During the blood-drawing process, nurses usually follow strict disinfection and aseptic operation protocols. If the nurse's hands did not directly touch the needle or the patient's blood, then even without changing gloves, infection theoretically would not occur directly. Infection typically requires pathogens to enter the body, and gloves serve as a physical barrier that can reduce the chance of direct skin contact with pathogens to some extent.

However, if gloves are not changed between different patients or between clean and contaminated areas, this barrier loses its protective function. The surface of the gloves may become contaminated with bacteria, viruses, or other pathogens from the previous patient or the environment, which can then be transferred to the next person or object surface being touched.

Nurses should change gloves each time they come into contact with different patients or when moving between clean and contaminated procedures, and should thoroughly wash their hands after removing gloves to ensure hand hygiene.
