Part Descriptions

LP15701-3   Leukocyte esterase
Leukocyte esterase (LE) is an enzyme contained in WBCs. 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. The LE test is also used to screen for gonorrhea and for amniotic fluid infections. The combination of the LE test with the urinary nitrite test provides an excellent tool for the presence of a UTI. A urine sample that tests positive for both nitrite and leukocyte esterase should be cultured for pathogenic bacteria.

LP20670-3   Leukocyte
Leukocytes or white blood cells (WBCs) are immune cells that fight infection, neoplasms and other inflammatory conditions, and mediate allergic responses. 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. Eosinophils and basophils respond to allergic reactions and are capable of ingesting antigen-antibody complexes. Monocytes phagocytose bacteria and release interferon to stimulate the immune system. Lymphocytes are divided into T-cells and B-cells. T-cell immunity is cellular and involves the activation of phagocytes and B-cell immunity uses antibodies to fight infection. Both elevated and low leukocyte counts can be markers of infection and malignancy, and low leukocyte counts are associated with a variety of primary and secondary immunodeficiencies, depending on the WBC type(s) that are out of range.
