Which type of laboratory test might a medical assistant perform?

A medical assistant is often responsible for performing basic laboratory tests and procedures that are within their scope of practice. Blood glucose monitoring is a common task that a medical assistant can undertake, as it involves using a glucometer to assess a patient’s blood sugar levels. This is particularly important for managing diabetes and ensuring that patients receive the appropriate care and interventions.

In contrast, other options like urinalysis interpretation, X-ray analysis, and electrocardiogram testing generally involve more specialized training or certification that goes beyond the typical role of a medical assistant. While they may assist with the processes around these tests or help in obtaining the samples, the actual interpretation or performance of such tests usually requires the expertise of a licensed professional such as a nurse or a physician. Therefore, blood glucose monitoring is specifically aligned with the duties of a medical assistant, making it the correct answer in this context.
