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 CD4 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. CD4 is a membrane glycoprotein found primarily on T lymphocytes, especially T helper (TH) cells, but also can be expressed on B cells, macrophages, and granulocytes. On T cells it is a co-receptor for the T cell receptor (TCR), interacts with MHC class II antigens, and functions to initiate or augment the early phase of T-cell activation.
Synonyms:exact_synonym: blood CD4(+) lymphocyte count to total lymphocyte count ratio
 related_synonym: blood CD4 lymphocyte count as percentage of total lymphocytes;   blood T helper cell percentage;   blood TH cell count to total lymphocyte count ratio
