The test for lactic acid dehydrogenase (LDH), also called lactate dehydrogenase (LD), measures the amount of this enzyme in your blood. LDH levels go up when there is damage to your cells.
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.
A health professional uses a needle to take a blood sample, usually from the arm.
The test will take a few minutes.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
