What is the lactate dehydrogenase or LDH Test?

Most body tissues like the brain, lungs, heart, and kidneys have LDH enzymes. An enzyme called lactate dehydrogenase supports our body's cellular respiration. The carbohydrates we consume are transformed into glucose and energy during cellular respiration. Usually, LDH remains inside the cell, but LDH is released into the bloodstream under abnormal conditions. In some instances of tissue injury, the enzyme remains elevated for up to 7 Days in the bloodstream. The lactate dehydrogenase test or LDH test measures the level of lactate dehydrogenase enzyme in the blood.
