[[Uric acid|Uric acid]] is also not a specific test for renal disease since other factors such as diet and ambient temperature also affect the levels. Increased plasma phosphate levels and a reversed [[Calcium|calcium]] to phosphate ratio are seen prior to changes in the [[Uric acid|uric acid]] level. [[lizard and Snake Imaging|Imaging]] may be useful and biopsy of the kidney gives the definitive diagnosis. | [[Uric acid|Uric acid]] is also not a specific test for renal disease since other factors such as diet and ambient temperature also affect the levels.
