Urine test strips, also known as urinalysis dipsticks, are simple diagnostic tools used to quickly screen and analyze the contents of urine. These small, plastic strips have multiple pads or reagent areas, each of which reacts with specific substances in the urine to change color. They are widely used in clinics, hospitals, laboratories, and sometimes at home for routine medical checkups, disease screening, and monitoring.

Blood (hematuria): Indicates infections, kidney stones, or trauma. Leukocytes: Suggests urinary tract infection (UTI). Nitrites: Also a marker for UTI (produced by certain bacteria). Ketones: Monitors diabetes, starvation, or metabolic disorders. pH: Measures urine acidity. Specific gravity: Assesses urine concentration (hydration status). Bilirubin and urobilinogen: Assesses liver function and hemolysis. Ascorbic acid (Vitamin C): May interfere with certain results.

How are Urine Test Strips Used?

Collect a fresh urine sample in a clean container. Dip the test strip briefly into the urine. Remove excess liquid by shaking off or blotting the strip.
