Lactic Acid Dehydrogenase


Lactate dehydrogenase (LD or LDH) is an enzyme which is important for the production of energy in the body. It is found in highest concentration in muscle cells, kidneys and the liver. Testing for lactate dehydrogenase levels in the blood is a non-specific test that can indicate a wide range of disorders or diseases since it is found in almost all the cells in the body. LDH is mostly released from cells when they are damaged or destroyed and is therefore, a good indicator for general cell and tissue damage.

This test is performed in following conditions such as:

• Monitoring conditions like cancer
• As part of a comprehensive metabolic panel
• When there is suspected disease which causes cell and tissue damage

Also Known As: LD, LDH


LDH testing does not have any special requirements.
