urease test

u·re·ase test

1. a test for urea based on the conversion of urea into ammonium carbonate by the enzyme urease;
2. a test for the production of urease, used for identification of Cryptococci and Helicobacter pylori.

pylori was assessed one month after the completion of treatment by performing a rapid urease test on gastric biopsy samples.
Biochemical analyses including pH, temperature, lactose fermentation test (LAC), indole test (IND), methyl red test (MR), Voges-Proskauer test (VP), urease test (URE), catalase test (CAT), aerobic and anaerobic test (Ae/An) were measured.
All the four samples were subjected to Direct Gram Stain, Rapid Urease Test and Culture [12-13].
