Which test checks for the presence of abnormalities in urine?

Urinalysis is the appropriate test for checking for the presence of abnormalities in urine. This comprehensive analysis evaluates various characteristics of urine such as its color, clarity, concentration, and chemical composition. It includes tests for substances like glucose, protein, ketones, and various pathogens, all of which can indicate underlying health issues such as infections, kidney diseases, or metabolic disorders.

In contrast, other tests listed do not focus specifically on urine analysis. A blood test assesses the presence of abnormalities in the blood, providing insights into organ function, disease presence, and overall health status. A biopsy involves taking a tissue sample from the body to examine whether there's the presence of disease, particularly cancer. Endoscopy is a procedure used to visualize the interior of certain organs and cavities in the body using a flexible tube with a camera, primarily for diagnosing issues not related to urine.

Hence, urinalysis stands out as the method specifically designed to analyze urine and detect any abnormalities.
