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.

LP19572-4 Lymphocytes.abnormal
The classification "abnormal lymphocyte" includes both variant lymphocytes (also known as atypical or reactive) and malignant lymphocytes (i.e., lymphoma cells). Lymphoma cells are sometimes difficult to distinguish from variant lymphocytes by microscopy alone. A few features that can help distinguish the two are the nuclear to cytoplasmic ratio, the shape of the nucleus, and cell heterogeneity. Variant lymphocytes have moderately abundant cytoplasm and oval nuclei with with notches or indentations and are heterogeneous in size and shape within a single smear. Lymphoma cells have less cytoplasm, nuclei that are round or oval with slight indentations and tend to have a more homogeneous appearance within a single smear.

- Change Reason
- Release 2.79: COMPONENT: Triggered by Coll w SCT: This is a specific fraction case where the denominator is percentage or /100. Because the logic is that the percentage piece is captured by Property: NFr (Numeric Fraction), and by Unit: %, therefore, it is redundant to include "100" in the component;
