What does a urinalysis primarily evaluate?

A urinalysis primarily evaluates the presence of infections or abnormalities in the urine, making it a key diagnostic tool in assessing various health conditions. The test examines factors such as pH, concentration, presence of protein, glucose, ketones, blood, and microscopic elements like bacteria or crystals, which can indicate infections or other underlying medical issues.

In terms of kidney function, while a urinalysis can provide some insights, it is not solely dedicated to evaluating kidney health, as other tests and evaluations are more specific for that purpose. Assessing blood glucose levels or liver enzymes is not the primary focus of a urinalysis; those tests are typically performed using blood samples. Therefore, the correct option highlights the main purpose of a urinalysis in detecting infections and abnormalities, which are critical for diagnosing a variety of health concerns.
