LDH or Lactic Acid Dehydrogenase is an enzyme that is found in almost all tissue in the body. It is responsible for converting glucose derived from food into energy. Cells then use this energy in order to function properly. Normal LDH levels in the blood range from 140 IU/liter to 333 IU/ liter.t is found in almost all body tissues and can be measured by a simple blood test. Normal LDH levels are generally low and range between 140 IU/liter to 333 IU/ liter. Low LDH levels are usually no cause for concern. However, elevated LDH levels may indicate cell damage.
