Medical gloves are disposable gloves used during medical examinations and procedures to help prevent cross-contamination between caregivers and patients. Medical gloves are made of different polymers including latex, nitrile rubber, polyvinyl chloride, and neoprene; they come un powdered or powdered with corn starch to lubricate the gloves, making them easier to put on the hands. There are two main types of medical gloves: examination and surgical. Surgical gloves have more precise sizing with better precision and sensitivity and are made to a higher standard. Examination gloves are available as either sterile or non-sterile, while surgical gloves are generally sterile.
