American Medical Certification Association (AMCA) Phlebotomy Practice Exam

Wearing gloves during blood draws is primarily critical to protect against bloodborne pathogens. This is essential in maintaining the safety of both the patient and the healthcare professional. Blood can carry various infectious agents, including viruses and bacteria that can lead to serious health issues if transmitted. Gloves provide a barrier that minimizes the risk of these pathogens entering the body through the skin, particularly if there are any cuts or abrasions present.

While preventing contamination is an important aspect of phlebotomy, it mainly pertains to ensuring that the blood sample itself remains uncontaminated during collection and handling. Although looking professional and keeping hands clean may have their merits in a clinical setting, they do not address the key safety and health risks involved in blood draws as effectively as protecting against pathogens does. Hence, the primary and most critical reason for wearing gloves is the protection they afford against potential exposure to infectious materials.
