Lactate Dehydrogenase Isoenzyme 2 (LD2) details
What Lactate Dehydrogenase Isoenzyme 2 (LD2) shows
LD isoenzyme 2 is a specific form of lactate dehydrogenase found predominantly in the immune system's white blood cells and red blood cells. Along with LD isoenzyme 1, it was historically used, particularly via the LD1/LD2 ratio, to help identify heart muscle damage or red blood cell breakdown, though this approach has largely been replaced in modern practice by more specific tests like troponin for cardiac injury.
Tests that include Lactate Dehydrogenase Isoenzyme 2 (LD2)
This panel measures lactate dehydrogenase isoenzymes. Lactate dehydrogenase (LD) is an enzyme found in almost all of the body's cells; elevated levels of this enzyme can be used as a general marker of cell injury. LD isoenzymes are used to determine the source of elevated LDH activity, as each isoenzyme tends to be concentrated in specific body tissues.
- Lactate Dehydrogenase (LDH) An enzyme found in many tissues, released when cells are damaged. A general marker used alongside other tests to investigate tissue injury, certain cancers, or red blood cell breakdown.
- Lactate Dehydrogenase Isoenzyme 1 (LD1) A specific form of LDH found mainly in heart muscle and red blood cells, historically used to help detect heart or blood-cell damage.
- Lactate Dehydrogenase Isoenzyme 2 (LD2) A specific form of LDH found mainly in the immune system and red blood cells.
- Lactate Dehydrogenase Isoenzyme 3 (LD3) A specific form of LDH found mainly in the lungs and other organs.
- Lactate Dehydrogenase Isoenzyme 4 (LD4) A specific form of LDH found mainly in the kidneys, placenta, and pancreas.
- Lactate Dehydrogenase Isoenzyme 5 (LD5) A specific form of LDH found mainly in the liver and skeletal muscle.
