NHA Phlebotomy Certification Practice Exam

What traditional duty is NOT performed by a phlebotomist?

1. Correct labeling of all specimens

2. Selecting appropriate specimen containers

3. Performing tests on patient samples

4. Collecting blood by venipuncture or dermal puncture

The correct answer is: Performing tests on patient samples

Phlebotomists play a critical role in the process of collecting blood samples, but their responsibilities typically do not include performing tests on those samples. Instead, phlebotomists are primarily focused on the collection of blood through various methods such as venipuncture (inserting a needle into a vein) or dermal puncture (using a lancet to collect blood from the skin). After collection, the blood samples are sent to laboratory professionals, such as medical laboratory technicians or technologists, who are specifically trained to conduct the tests needed for diagnosis or monitoring of medical conditions. The distinction is important in understanding the roles within the healthcare team, as each member has specialized skills that contribute to patient care. Therefore, performing tests on patient samples falls outside the traditional scope of practice for phlebotomists, emphasizing their primary duties related to specimen collection, labeling, and proper handling of blood samples.
