Lactate dehydrogenase (LDH) has a wide distribution in reptile tissues and elevations suggest tissue damage. In some species elevations over 1000 iu/l are considered significant.  An increased value for LDH indicates tissue damage.

*'''Alanine aminotransferase''' - Elevated blood values of alanine aminotransferase (ALT), formerly glutamic-pyruvic transaminase, GPT or SGPT, are not specific for one tissue and are not a reliable indicator of liver or muscle damage. ALT is not usually part of routine biochemistry.

*'''[[Alanine aminotransferase|Alanine aminotransferase]]''' - Elevated blood values of alanine aminotransferase (ALT), formerly glutamic-pyruvic transaminase, GPT or SGPT, are not specific for one tissue and are not a reliable indicator of liver or muscle damage. ALT is not usually part of routine biochemistry.

*'''Alkaline phosphatase''' - Alkaline phosphatase (AP, ALP) is widely distributed in tissue and generally at low levels. Low tissue activity and lack of tissue specificity limit the use of AP as a diagnostic indicator in reptiles.

*'''Bilirubin''' - Assessment of bilirubin is not a useful diagnostic test since the major bile pigment of reptiles is biliverdin. Bilirubin cannot be detected or occurs at low concentrations. Plasma elevations of biliverdin may be useful in the diagnosis of liver-associated disease.

*'''Creatinine''' - Normal plasma creatinine values for reptiles are very low and are a poor diagnostic indicator in reptiles.
