LDH

LDH is an enzyme produced in various cells of the body, including the liver, heart, kidney, and red blood cells, and works to convert carbohydrates into energy. When an organ is destroyed due to some abnormality, LDH leaks into the blood and the level rises. LDH may be increased in diseases of the liver, heart, lungs, kidneys, blood, skeletal muscle, and malignant tumors.
