LDH (Lactate Dehydrogenase)

LDH (Lactate Dehydrogenase) is an enzyme found in many tissues, including the heart, liver, muscles, kidneys, lungs, and blood cells. The LDH blood test measures enzyme levels released into the bloodstream when tissues are damaged. Elevated LDH levels may indicate conditions such as anemia, liver disease, muscle injury, infections, heart disorders, or certain cancers. Although LDH is a non-specific marker, it is valuable in monitoring disease progression, tissue damage, and treatment response. The test is often interpreted alongside other laboratory and clinical findings to identify the underlying cause of elevated enzyme levels.
