Objectives: Urinalysis is one of the most frequently ordered diagnostic laboratory tests. In order to reduce workload and costs, rapid screening tests such as urine test strip analyses are applied. The aim of this study was to evaluate the analytical performance of the UC as well as the diagnostic performance in comparison with reference methods. Design and methods: We measured within-run and between-run imprecision based on quantitative reflectance values.
Leukocytes in Urine: What Does Leukocyte Esterase in Urine Mean?

In fluids that are usually cell "free", detection of this enzyme indicates the presence of a significant number of WBCs which can signal infection or inflammation. In urine, this test is used to detect white blood cells and other abnormalities associated with infections. White blood cells in the urine usually indicate a urinary tract infection UTI. The LE test detects esterase, an enzyme released by white blood cells. Testing for LE is a routine part of the urine dip stick, and helps to diagnose urinary tract infections. Positive test results are clinically significant.

Leukocytes, also known as white blood cells, are a central part of the immune system. They help to protect the body against foreign substances, microbes, and infectious diseases. These cells are produced or stored in various locations throughout the body, including the thymus, spleen, lymph nodes, and bone marrow. High leukocyte levels suggest that the body is trying to fight an infection. Leukocytes travel throughout the body, moving between the organs and nodes and monitoring any potentially problematic germs or infections.
There are five types of WBCs normally present in the circulation that are all derived from a similar stem cell in the bone marrow. The five type of WBCs are divided into two groups based on the presence or absence of granules in the cytoplasm. The granulocytes include the neutrophils, basophils and eosinophils. The non-granulocytes include the lymphocytes and the monocytes. The neutrophils fight infection by ingesting and digesting bacteria.
