Frequent Urination Due to Urinary Tract Infection

Urinary Tract Infection (UTI) is the most common cause of sudden or persistent urinary urgency. Confirmation is achieved through a clinical urinalysis, where a healthcare provider tests a urine sample for the presence of nitrites, leukocyte esterase, white blood cells, or bacteria. A positive result in these specific markers, often accompanied by symptoms like burning during urination or cloudy urine, confirms an active infection.
