71678-7Lymphocytes/Leukocytes [Pure number fraction] in Blood by Automated countActive

Term Description

Because of the confusion that occurs in countries that report results as both decimal fraction and percent, this property was created to represent decimal fractions that are reported without units.

Part Descriptions

LP14540-6   Lymphocytes
White blood cells formed in lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin whereas the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T cells (transit through the thymus), B cells or natural killer cells (NK). Source: National Library of Medicine, MeSH 2006

LP14540-6   Lymphocytes
A lymphocyte is a type of white blood cell in the vertebrate immune system.

A lymphocyte count is usually part of a peripheral complete blood cell count and is expressed as percentage of lymphocytes to total white blood cells counted. A general increase in the number of lymphocytes is known as lymphocytosis whereas a decrease is lymphocytopenia.

An increase in lymphocyte concentration is usually a sign of a viral infection (in some rare case, leukemias are found through an abnormally raised lymphocyte count in an otherwise normal person).

A low normal to low absolute lymphocyte concentration is associated with increased rates of infection after surgery or trauma.

LP157588-7   Leukocytes
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.
