What does a positive result for leukocyte esterase and nitrites in urine typically suggest?

• A. Dehydration
• B. Kidney disease
• C. Urinary tract infection (UTI)
• D. Diabetes

Answer: (C)

A positive result for leukocyte esterase and nitrites in urine typically suggests the presence of a urinary tract infection (UTI). This is because leukocyte esterase is an enzyme produced by white blood cells (WBCs), indicating inflammation or infection in the urinary tract. The presence of nitrites is linked to specific bacteria that convert nitrate to nitrite, which are common pathogens associated with UTIs, such as Escherichia coli.

When both leukocyte esterase and nitrites are detected, it strongly indicates that there is an active infection in the urinary tract, warranting further investigation and treatment. The combination of these two results serves as a reliable diagnostic tool for healthcare providers in identifying UTIs in patients presenting with related symptoms.

Other options, such as dehydration or kidney disease, do not typically present with both leukocyte esterase and nitrites, and diabetes, while it can cause various urinary changes, is not specifically indicated by these tests. Thus, the evidence points clearly to a UTI as the condition reflected by the positive test results.
