What is normal range for LD?

Normal LDH levels range from 140 units per liter (U/L) to 280 U/L or 2.34 mkat/L to 4.68 mkat/L. Many diseases can cause LDH levels to go up. Other tests are usually needed to confirm a diagnosis.

What does LDH lab test for?

LDH is most often measured to check for tissue damage. LDH is in many body tissues, especially the heart, liver, kidney, muscles, brain, blood cells, and lungs. Other conditions for which the test may be done include: Low red blood cell count ( anemia )

Can LDH test detect cancer?

LDH is not used to diagnose cancer but can be used to see how well treatment is working. LDH can be used to monitor treatment in testicular cancer, ovarian cancer, lymphoma, leukemia, melanoma, and neuroblastoma. LDH levels can also be elevated by many noncancerous conditions such as heart, lung, or kidney disease.

What does it mean if your LDH is high?

Higher than normal LDH levels usually means you have some type of tissue damage or disease. Disorders that cause high LDH levels include: Anemia. Kidney disease.

How high is LDH in cancer?

Regardless of primary cancer type, patients with advanced cancer have much in common, such as fatigue, pain, and heavy tumor burden. Few studies have evaluated the value of LDH >1000 IU/L (four times upper limit of normal, ULN) as a predictor of survival time in metastatic cancer patients.

When to use LD as a screening test?

LD may be used as a screening test when some kind of cellular or tissue damage is suspected. If the LD is high other, more specific tests such as CK, ALT and AST can be used to help pinpoint the organs involved. Once the problem is diagnosed, LD levels may be tested at regular intervals to monitor its progress.

What are the different types of LDH tests?

If your LDH levels are higher than normal, your doctor may order more tests to pinpoint where the damage is located. One of them looks at levels of your LDH isoenzymes. These are types of LDH. There are five different forms, ranging from LD-1 through LD-5. Each of the five tends to be concentrated in specific body tissues.

What kind of test is lactate dehydrogenase ( LDH )?

This test measures the level of the different lactate dehydrogenase (LDH) isoenzymes in the blood. LDH, also known as lactic acid, is a type of protein, known as an enzyme. LDH plays an important role in making your body’s energy. It is found in almost all the body’s tissues. There are five types of LDH. They are known as isoenzymes.

How is a blood sample for LD taken?

A blood sample is obtained by inserting a needle into a vein in the arm. Is any test preparation needed to ensure the quality of the sample? No test preparation is needed. How is it used? The main use for LD is as a general indication of cell damage, including muscle damage, liver damage, blood cell damage and cancers.

What is a lactate dehydrogenase ( LDH ) test?

What is a lactate dehydrogenase (LDH) test? This test measures the level of lactate dehydrogenase (LDH), also known as lactic acid dehydrogenase, in your blood or sometimes in other body fluids. LDH is a type of protein, known as an enzyme.
