Lactate Dehydrogenase (LDH) Isoenzymes Test
What is a Lactate Dehydrogenase (LDH) Isoenzymes Test?
A Lactate Dehydrogenase (LDH) Isoenzymes Test is a blood test that examines for the presence of LDH in the blood. LDH is an enzyme found mainly in body cells and it helps to break down carbohydrate molecules (or energy). The test helps measure the levels of LDH present in the blood. Higher levels than normal can indicate the presence of certain cancers, tissue damage, or other medical conditions.
Preparation for the test
Your doctor may ask you to fast for a few hours before the test. You may also be asked to stop taking any medications that may affect the results of the test. Your doctor may also request a blood sample to be taken before or after the LDH Isoenzymes Test.
Procedure
The LDH Isoenzymes Test requires a blood sample to be taken from a vein in the arm or hand. The blood sample is then sent to a lab where it is tested for elevation in levels of LDH. The results of the LDH Isoenzymes Test will typically be available within a few days.
Types of LDH Isoenzymes Test
There are two major types of LDH Isoenzymes Test: the qualitative and quantitative tests. The qualitative test only detects if the LDH levels are above the normal range. The quantitative test is more specific and can detect exactly how much the LDH levels are above the normal range.
Risks
The LDH Isoenzymes Test is generally a safe test with very few risks or side effects. There may be some bruising or soreness at the injection site, or, in rare cases, infection may occur. Other than that, there are no other risks associated with the test.
Why is the LDH Isoenzymes Test done?
The LDH Isoenzymes Test is typically done to help diagnose certain types of cancer or to determine if tissue damage has occurred. It is often used to help diagnose things such as cardiac issues, liver and kidney problems, and other metabolic problems.
When is the LDH Isoenzymes Test done?
The LDH Isoenzymes Test is typically done when certain symptoms or illnesses are present. It is often done in conjunction with other tests or imaging scans to help provide a better picture of the illness or medical condition.
