Changes

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.

==Not commonly used==

==Tests not commonly used:==

*'''[[Alanine aminotransferase|Alanine aminotransferase]]''' - Elevated blood values of [[Alanine aminotransferase|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|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]]''' - [[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.

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

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

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

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

*'''Gamma glutamyl transferase (GGT)''' - Gamma glutamyl transferase (GGT) activity in plasma and tissue is low or undetectable and GGT appears to be of little diagnostic use.

*'''Gamma glutamyl transferase (GGT)''' - Gamma glutamyl transferase (GGT) activity in plasma and tissue is low or undetectable and GGT appears to be of little diagnostic use.

*'''Urea''' - Since reptiles are primarily uricotelic, blood urea of most reptiles is low.  It is generally considered a poor diagnostic indicator for renal disease in snakes.
