CLINICAL MEASUREMENT - ANNOTATIONS

The Clinical Measurement Ontology (CMO), Measurement Methods Ontology (MMO), and Experimental Condition Ontology (XCO) are currently being developed at the Rat Genome Database. For more information about these vocabularies please see Shimoyama et al. Three ontologies to define phenotype measurement data. Front Genet. 2012;3:87.

Definition:A calculated measurement in which the number of lymphocytes expressing the CD25 antigen on their surface in a specified sample of blood is divided by the total number of lymphocytes in the sample, and the result presented as a ratio, fraction, quotient or percentage. CD25 is the alpha chain of the IL-2 receptor and is used as a marker of activated T cells, although it can also be found on other leukocytes including some monocytes, B cells, thymocytes and myeloid precursor cells. CD25 is expressed on a subset of resting T cells but at a much lower level than found on activated cells.
Synonyms:exact_synonym: blood CD25(+) lymphocyte count to total lymphocyte count ratio
 related_synonym: blood CD25 lymphocyte count as percentage of total lymphocytes;   blood activated T cell count to total lymphocyte count ratio;   blood activated T cell percentage
