The Urease test is a biochemical test that detects the alkaline fermentation of urine (urea) with the resultant production of ammonia by microorganisms.

The fermentation of urea occurs in the presence of the enzyme ‘urease’, resulting in two molecules of ammonia and carbon dioxide. Urease activity is one of the important characteristics for the identification of Proteus species and allows for Proteus to be distinguished from non-lactose-fermenting members of the Enterobacteriaceae. Christensen developed the test in 1946 for the differentiation of enteric bacilli. The urea agar base used for the testing of urease activity is named Christensen Urea Agar after him. During the test, the organisms utilize urea as the sole source of nitrogen, producing a sufficient amount of ammonia to overcome the buffering capacity of the medium. The change in color of the medium as a result of the ...
