This test will determine the level of lactate dehydrogenase (LDH), also known as lactic acid dehydrogenase in your blood or sometimes in other body fluids.LDH is a picture of a protein known as an enzyme.LDH plays an important role in making energy to your body. It occurs in almost all body tissues, in the blood, heart, kidneys, brain, and a quantity of non-living tissues.
When these tissues are damaged, they release LDH in the bloodstream or other body water. A high LDH content in the blood or water may mean that certain tissues in the body have been damaged by disease or injury.
Other name: LD Test, lactic dehydrogenase , lactic acid dehydrogenase
What is it used for?
The LDH test is the most used test.
- Look for damage to the fabric.
- Note disorders that cause tissue damage. These include anemia, liver damage, nonsevere disorders, and some forms of infection.
- Monitor chemotherapy for specific types of cancer. This test can indicate whether the therapy is working.
Why is the LDH test needed?
This study may be needed if other studies or symptoms indicate that there is tissue damage or disease. Symptoms depend on the type of tissue damage.
You may also need an LDH test if you are being treated for cancer.
What happens during the LDH test?
The caregiver takes a blood sample from a vein in the arm with a small needle. After the needle is inserted, a small amount of blood is collected into a test tube or vial. Some pressure can be felt as the needle goes in and out. This usually takes less than 5 minutes.
LDH may also be measured in other body fluids, such as spinal fluid, non-tumor, and abdominal. When one of these tests is completed, the physician will provide more information about the procedure.
Need to prepare for the test?
No special substances are needed for the LDH blood test.
Are there any risks associated with the test?
The risks associated with blood testing are not sufficient. The area where the needle is inserted can be slightly sore or bruised, but most signs disappear quickly.
What do the results mean?
A higher than normal LDH value usually means that there is some type of tissue damage or disease. Disorders that cause the highest LDH levels include
- anemia
- Kidney disease
- Liver disease
- Muscle trauma
- Acute heart and vascular disease
- Pancreatitis
- Meningitis, encephalitis, infections including infectious mononucleosis (mono)
- Certain types of cancer, such as lymphoma and leukemia. A more elevated LDH content means the cancer is not curable.
This test can indicate whether there is tissue damage or disease, but he does not indicate where the damage is. If the results show higher than normal LDH levels, the physician may need to perform further tests to make a diagnosis. One of these tests is the LDH Isoenzym analysis; LDH-Isoenzym determines all the different forms of LDH. This helps the physician recognize the location, type, and severity of tissue damage.
If you have questions about your results, please consult your health care provider.
