  • Liver disease

  • Adults: 100-190 U/L


For cerebrospinal fluid, the normal range for newborns is 70 U/L and for adults is 40 U/L.

High LDH levels may indicate an infection or inflammation in the central nervous system. 

Elevated LDH does not necessarily mean that there is something wrong. Your doctor is the only one who should interpret the results and he/she may even order more tests such as ALT, AST or ALP to be sure of the diagnosis.
