What is a common test performed by medical technologists to assess kidney function?

Urinalysis is a common test performed by medical technologists to assess kidney function. This test analyzes the physical, chemical, and microscopic properties of urine. Through urinalysis, various indicators of kidney health can be detected, such as the presence of proteins, glucose, ketones, hemoglobin, and specific gravity of the urine, all of which can provide insight into how well the kidneys are filtering waste and maintaining balance in the body.

The other tests mentioned serve different purposes. A complete blood count provides information on various components of blood but does not specifically indicate kidney function. An electrocardiogram measures the electrical activity of the heart and is not related to kidney assessment. Similarly, a chest X-ray focuses on the structures within the chest, such as the lungs and heart, rather than kidney health. Urinalysis stands out as the primary laboratory test to evaluate kidney function effectively.
