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. Epub 2012 May 28 or contact us (http://rgd.mcw.edu/contact/index.shtml).

Definition:This is a method using a device designed to follow a predetermined sequence of individual operations repeatedly and essentially without external influence or control to measure the amount of nitrogen present in plasma, the clear liquid that separates from blood after cells and platelets have been removed. Urea is the chief nitrogenous end product of protein metabolism and is formed in the liver from amino acids and from ammonia compounds and is found in urine, blood, and lymph.
