WBC Esterase Trace is a diagnostic test used in the medical field to detect the presence of white blood cells (WBCs) in bodily fluids. It is an important tool for assessing and monitoring various health conditions, including infections and inflammatory diseases.

The test works by detecting the enzyme esterase, which is released by white blood cells during an immune response. The presence of esterase indicates the presence of WBCs. The WBC Esterase Trace test is commonly used to analyze urine samples, as well as other fluids such as cerebrospinal fluid or joint fluid.

By measuring the concentration of esterase, medical professionals can determine the level of white blood cells in a sample. Elevated levels may indicate the presence of an infection or inflammation, while lower levels may be a sign of a compromised immune system. The test is especially useful for diagnosing urinary tract infections (UTIs) and other conditions affecting the urinary system.

Overall, the WBC Esterase Trace test is a valuable tool in the medical field, providing crucial information about a patient’s immune response and potential health issues. It helps healthcare professionals make accurate diagnoses and develop appropriate treatment plans for their patients.
