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 CD8 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. CD8 is a glycoprotein on the surface of killer (suppressor/cytotoxic) T lymphocytes that enhances binding with major histocompatibility complex molecules.
Synonyms:exact_synonym: blood CD8(+) cell count to total lymphocyte count ratio
 related_synonym: blood CD8 lymphocyte count as percentage of total lymphocytes;   blood T(S/C) cell count to total lymphocyte count ratio;   blood suppressor/cytotoxic T cell percentage
