Lactate Dehydrogenase Isoenzymes (LDH) Blood Test


Test Code: 001842
Specimen Type: Blood

Description:

Lactate Dehydrogenase Isoenzymes (LDH) Blood Test (Labcorp)

This test measures the percentage of different forms of Lactate Dehydrogenase (LDH) in the blood.  LDH is an enzyme which is found in a number of different tissues in the body.  When tissues are damaged, LDH is released.  Measuring total LDH can help to determine if there has been tissue damage but cannot identify where the damage has occurred.  An Isoenzyme test breaks down the 5 types of LDH and measures how much of each one is present.  This can help narrow down where damage may have occurred.

  • LD-1 is primarily found in the heart, kidneys, and blood cells
  • LD-2 is primarily found in the heart, kidneys, and red blood cells but in lesser amounts than LD-1
  • LD-3 is primarily found in the lungs
  • LD-4 is primarily found in the white blood cells, lymph nodes, muscles, and liver
  • LD-5 is primarily found in the liver and skeletal muscles

A number of conditions can cause elevated LDH levels.  These include stroke, lung disease, pancreatitis, muscle injury, liver disease, mononucleosis, hemolytic anemia, and heart disease.  An LDH Isoenzymes test is sometimes ordered as a followup to abnormal results on a high Lactic Acid Dehydrogenase test.  It may also be ordered when someone is suspected of having a condition related to tissue damage to help make a diagnosis.

Turnaround for this test is typically 4-7 business days.
