Urinary tract infections (UTIs) are one of the most common infections worldwide. They can affect people of all ages and can lead to discomfort and complications if left untreated. Therefore, early and accurate diagnosis is crucial for effective management and treatment.

One of the diagnostic tools used in the evaluation of UTIs is the Leukocyte Esterase Urinalysis (UA) test. This simple and non-invasive test helps to detect the presence of white blood cells (leukocytes) in the urine. White blood cells are a key indicator of inflammation and infection in the urinary tract.

The Leukocyte Esterase UA test works by detecting the presence of an enzyme called esterase, which is released by white blood cells when there is an infection. The test is often performed in conjunction with a urine culture to determine the type of bacteria causing the infection.

Results from the Leukocyte Esterase UA test are classified as negative, trace, or positive, indicating the level of leukocyte activity in the urine. A negative result suggests the absence of infection, while a positive result indicates the presence of leukocytes and possible infection. A trace result suggests a low level of leukocytes, which may warrant further investigation.
