Changes

Urea and [[Creatinine in lizards|creatinine]] blood levels are not useful in the diagnosis of renal disease in reptiles. Snakes are uricotelic and [[Uric acid|uric acid]] levels increase with kidney failure. However, it is not a sensitive test for renal disease since damage to two thirds of the kidney may be necessary before an increase will be seen.

[[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.
