LDH

LDH, or lactate dehydrogenase, is an enzyme present in many body tissues like the heart, liver, muscles, and blood cells. It plays a key role in energy production by helping convert sugar into energy. When tissues are damaged due to conditions like injury, infection, or disease, LDH can be released into the bloodstream, leading to higher levels detectable through blood tests. Measuring LDH helps doctors assess tissue damage or monitor certain illnesses, but since it’s found in many tissues, elevated levels usually indicate that some kind of tissue injury has occurred.
