Which of the following roles is within an assistant/technician's responsibilities?

Conducting laboratory tests is a responsibility that falls within the scope of practice for veterinary technicians. Technicians are trained to perform a variety of laboratory procedures, such as analyzing blood samples, conducting urinalysis, and preparing samples for microscopy. These tasks require specialized training and skill, and they play a crucial role in the diagnostic process, allowing veterinarians to make informed treatment decisions based on laboratory results.

In contrast, performing surgery and diagnosing illnesses are roles typically reserved for licensed veterinarians due to the need for advanced medical knowledge and the authority to make medical judgments. Administering vaccines, like the rabies vaccine, is often performed by technicians under the supervision of a veterinarian, but it may also require specific legal regulations and protocols to be followed, depending on the jurisdiction or practice setting. Thus, while technicians play a supportive role in vaccination processes, certain responsibilities, like diagnosing illnesses or performing surgeries, exceed the authorized scope of their practice.
