<prompt> Specific test for gout is:Raised serum uric acid levelRaised uric acid in synol fluid of jointRaised urea levelRaised urease enzyme level  <response>: B i.e. Raised uric acid in synol fluid of joint - Gout is a metabolic disorder of purine catabolismQ, and characterized by high level of uric acid in the blood . Uric acid is end product of purine catabolismQ - Pyrimidine nucleotide unlike purine rings can be opened degraded to highly water soluble structure like, p- alanine, 3? amino isobutyrate, NH3 CO2. Excess meabolism of pyrimidine therefore does not give rise to clinical manifestationQ Human catabolizes purine Adenine Guamine to uric acid, which is relatively insoluble acid.
