Lactic acid dehydrogenase (LDH) is an enzyme, Opens dialog that helps produce energy. It is present in almost all of the tissues in the body and its levels rise in response to cell damage. LDH levels are measured from a sample of blood taken from a vein.
LDH levels help find the cause of lung disease, lymphoma, anemia, and liver disease. They also help find out how well treatment for lymphoma is working.
In general, there's nothing you have to do before this test, unless your doctor tells you to.
Information about Lactic Acid Dehydrogenase (LDH) Test
A health professional uses a needle to take a blood sample, usually from the arm.
How long the test takes
The test will take a few minutes.
Each lab has a different range for what's normal. Your lab report should show the range that your lab uses for each test. The normal range is just a guide. Your doctor will also look at your results based on your age, health, and other factors. A value that isn't in the normal range may still be normal for you.
Many diseases can cause LDH levels to go up. Other tests are usually needed to confirm a diagnosis.
For many healthy people, a slightly high LDH isn't serious. It can happen because of exercise or because of a technical problem with the test.
