What are the five isoenzymes of LDH?

There are five different forms of LDH that are called isoenzymes. They are distinguished by slight differences in their structure. The isoenzymes of LDH are LDH-1, LDH-2, LDH-3, LDH-4, and LDH-5. Different LDH isoenzymes are found in different body tissues.

What does LDH indicate?

An LDH test is most often used to: Find out if you have tissue damage. Monitor disorders that cause tissue damage. These include anemia, liver disease, lung disease, and some types of infections.

What does it mean if LDH is high?

What is the normal range of LDH?

Normal Results Normal value range is 105 to 333 international units per liter (IU/L). Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific results.

How many isoenzymes of LDH are there?

There are five types of LDH. They are known as isoenzymes. The five isoenzymes are found in different amounts in tissues throughout the body.

What are the five 5 LDH isoenzymes and where they are found in the body?

LDH isoenzymes are found in many tissues in the body, including the heart, red blood cells, liver, kidneys, brain, lungs, and skeletal muscles. LDH exists in 5 isoenzymes. Each isoenzyme has a slightly different structure and is found in different concentrations in different tissues.

How do I lower my LDH levels?

Anesthetics, aspirin, narcotics, and certain other medicines can raise your LDH. Medicines with ascorbic acid (vitamin C) can decrease your LDH levels. Alcohol also can affect your LDH levels.
