Lactic Acid Dehydrogenase (LDH)


This blood test measures Lactic Acid Dehydrogenase (LDH) levels. Lactic Acid Dehydrogenase (LDH) is an enzyme that is present in most tissues in the body, especially the heart, liver, kidney, skeletal muscle, brain, lungs and blood.

LDH plays an active role in the production of energy and is used to measure cellular damage. Elevated levels of LDH are associated with cardiovascular disease, anemia, tissue destruction, viral infections and Vitamin B12 deficiency.

Test Preparation For Optimal Results:

If possible, have the lab collected early in the morning or shortly after waking. For comparison purposes, have subsequent labs collected close to the same time.

Disclaimer: A health care provider should evaluate a deviation from normal ranges.
