MEASUREMENT METHODS - 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:An instrument used for manual, microscopic counting of cells in suspension and consisting of a glass microscope slide with a rectangular indentation that creates a chamber. The chamber is engraved with a precise laser-etched grid of perpendicular lines and the depth of the chamber is standardized so that the volume of fluid and cells contained within a grid square and between the slide and the cover glass is known, allowing a count per volume to be determined.
Synonyms:exact_synonym: haemocytometer;   hemacytometer
