A variety of disease conditions can cause elevations in total LDH. Differentiation can be provided by isoenzyme analysis, i.e. LDH1 (haemolysis), LDH2 (cardiac), LDH4 (intestinal) and LDH5 (skeletal or hepatic).
Total LDH levels are age-dependent to maturity and reference ranges must be consulted when interpreting results for young horses.
Artefactual increases can occur with haemolysis, and serum concentrations are higher than plasma.
