1 Obtain your tube and compare it to a control. 2  If the color is intensely deep pink after 2 days, it is positive for rapid urease hydrolysis.  If it is yellow or orange, the test is negative. The organism either does not hydrolyze urea rapidly or it cannot live in the medium.
Procedure for urease test. 1  Streak the surface of a urea agar slant with a portion of well isolated colony. 2  Leave the cap on loosely and incubate the test tube at 35 in ambient air for 48 hours to 7 days. 3  If organism produces urease enzyme, the color of the slant changes from light orange to magenta.
