LP31538-9   Leukocyte clumps
Leukocyte clumps are white blood cells grouped together by agglutination. Leukocyte clumps in urine indicate the presence of an infection or inflammation, especially in the kidney (e.g. pyelonephritis, interstitial inflammation, parenchymal infections). Leukocyte clumps in the blood may be associated with cancer, including non-Hodgkins lymphoma and chronic lymphocytic leukemia. Source: Regenstrief LOINC

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.
