LP14267-6   Neutrophils
Neutrophils are the most common form of white blood cells in healthy adults. Neutrophils are approximately 13 micrometers in diameter and have segmented nuclei with 3-5 lobes that are connected by thin strands of chromatin. (Practical Haematology; Barbara J. Bain, Imelda Bates, Mike A. Laffan,S. Mitchell Lewis; Eleventh edition; 2012) Neutrophils function to fight infection by both engulfing microorganisms and secreting lethal enzymes.
(https://www.ncbi.nlm.nih.gov/pubmedhealth/PMHT0022058/) They are produced in the bone marrow and their primary function is to fight infection. Neutrophil numbers increase in the blood in response to acute bacterial infection, inflammation, necrosis or chronic myelogenous leukemia. Neutrophil levels are decreased in the following conditions: aplastic anemia, autoimmune disorder, cancer, chemotherapy, myelodysplastic syndrome and during a negative reaction to drugs.

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.

LP7238-1   Body fld
The LOINC "Body fld" System represents body fluids other than serum, plasma, blood, urine, and cerebrospinal fluid. When a LOINC term with the System "Body fld" is used, the specific specimen source or body fluid type should be reported elsewhere with the result. Where more specific terms for pleural, peritoneal, synovial fluid, etc. exist, we encourage you to use the more specific terms. In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" is used for abnormal fluid collections that are aspirated, while "Body fld" is used for named body fluids, such as synovial fluid or peritoneal fluid, that are not inherently pathologic.

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;
