Leukocyte esterase is typically tested using a urine dipstick test. A chemical strip is dipped into a urine sample, and the strip changes color in the presence of leukocyte esterase. This test can provide rapid results and is often used in clinical settings for initial screening. It is important to note that while the dipstick test is convenient, it can sometimes yield false positives or negatives, necessitating further confirmatory tests such as urine microscopy or urine culture.
