LDH: Lactate dehydrogenase is an enzyme that catalyzes the conversion of lactate to pyruvate. This is an important step in energy production in cells. Many different types of cells in the body contain this enzyme. Some of the organs relatively rich in LDH are heart, kidney, liver, and muscle.

As cells die their LDH is released and finds its way into the blood. Normal LDH levels vary with age, being higher in childhood due to bone growth. Analysis of LDH has not been standardized and normal ranges vary greatly between laboratories. Generally, the upper limit of normal for adults is in the range of 200 units/liter.
