• A. CT scan of the abdomen
• B. Urinalysis
• C. Rectal examination
• D. X-ray of the bladder

While a dipstick test provides rapid preliminary results by detecting the presence of nitrites, leukocyte esterase, and blood, a comprehensive urinalysis goes further by examining the physical and chemical properties of urine, as well as the microscopic presence of cells, bacteria, and crystals.

A urinalysis can confirm the presence of bacteria, white blood cells, and red blood cells, which are indicators of infection. It can also provide insights into potential complications or other underlying issues affecting the urinary tract. This thorough examination can help healthcare providers gain a more complete understanding of the urinary system's status and the specific nature of the infection, thus guiding appropriate treatment.

In contrast, other methods such as a CT scan of the abdomen, rectal examination, and X-ray of the bladder are not standard practices for diagnosing UTIs. A CT scan typically evaluates for complications or alternative diagnoses, but it is not specifically targeted for diagnosing a UTI. A rectal examination might be relevant in certain male patients to assess for prostate issues that could complicate a UTI but does not directly identify the infection itself. An X-ray of
