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:A test which measures the amount of nitrogen in the form of urea present in serum, the clear liquid that separates from blood after it has clotted completely. 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.
