The lactate dehydrogenase (LDH) test measures the amount of LDH in the blood.
See also: LDH isoenzymes
Alternative NamesLDH test; Lactic acid dehydrogenase test
How the test is performedThe health care provider will take blood from a vein or from your heel, finger, toe, or earlobe.
The blood sample is sent to a laboratory, where it is placed in a machine called a centrifuge. The machine quickly spins the blood, which causes the liquid part (the serum) to separate from the cells. The LDH measurement is done on the serum.
How to prepare for the testYour health care provider may ask you to stop taking drugs that may affect the test. Drugs that can increase LDH measurements include anesthetics, aspirin, clofibrate, fluorides, mithramycin, narcotics, and procainamide.
Why the test is performedLDH is most often measured to check for tissue damage. The enzyme LDH is in many body tissues, especially the heart, liver, kidney, skeletal muscle, brain, blood cells, and lungs.
Other conditions under which the test may be done:
Normal ValuesA typical range is 105 - 333 IU/L (international units per liter).
Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What abnormal results meanHigher-than-normal levels may indicate:
- Blood flow deficiency (ischemia)
- Cerebrovascular accident (such as a stroke)
- Heart attack
- Hemolytic anemia
- Infectious mononucleosis
- Liver disease(for example, hepatitis)
- Low blood pressure
- Muscle injury
- Muscular dystrophy
- New abnormal tissue formation (usually cancer)
- Pancreatitis
- Tissue death
If the LDH level is raised, your doctor may order an LDH isoenzymes test.

What else can I help you with?
A LDH blood test tests for what?
A LDH blood test measures the level of lactate dehydrogenase, an enzyme found in the body's tissues and organs. Elevated LDH levels may indicate tissue damage or diseases such as liver disease, heart attack, or certain types of cancer.
What blood test requires slurry ice?
Blood tests that require slurry ice typically involve testing for certain enzymes or proteins that are temperature-sensitive and can degrade if not kept at a very low temperature. Examples include tests for ammonia, lactate dehydrogenase, and pyruvate kinase. The use of slurry ice helps to maintain the stability of these substances during transportation and processing.

What is the name of the thiamine blood test?
The name of the thiamine blood test is "Thiamine (Vitamin B1) Blood Test" or simply "Thiamine Blood Test."
What color test tube for a lipid test?
A clear or transparent test tube is typically used for a lipid test to easily observe any color changes or reactions that occur during the test.
A LDH blood test tests for what?
A LDH blood test measures the level of lactate dehydrogenase, an enzyme found in the body's tissues and organs. Elevated LDH levels may indicate tissue damage or diseases such as liver disease, heart attack, or certain types of cancer.

Can someone tell you why you are lactating you took a pregnancy test it was neg but your brest are sore and you have the signs you never lactate unless you are pregnant you had your period last month?
can someone tell me why i am lactating and i have took a pregnancy test and it was neg. the only time i do lactate is when i am pregnant can so someone please answer my question.......?
What does elevated LD mean in a blood test?
Elevated LD, or lactate dehydrogenase, in a blood test typically indicates tissue damage or cell death. LD is an enzyme found in many tissues throughout the body, and increased levels can be seen in conditions such as heart attack, liver disease, muscle injury, or certain cancers. Further investigation is usually needed to determine the specific cause of the elevated LD levels and to guide appropriate treatment.
What is a test for nonspecific tissue damage?
A common test for nonspecific tissue damage is the measurement of serum levels of enzymes such as creatine kinase (CK) and lactate dehydrogenase (LDH). Elevated levels of these enzymes can indicate tissue damage due to various causes, including muscle injury, heart attack, or liver disease. Additionally, the presence of inflammatory markers like C-reactive protein (CRP) can also suggest nonspecific tissue damage. These tests help assess the extent of damage but do not pinpoint the exact cause.
Is it normal to have fore milk when blood test came your negative?
No, you need a further medical work up to determine what is causing you to lactate.
Which test can be done on a hemolyzed specimen?
While hemolysis can interfere with many tests, some tests can still be performed on a hemolyzed specimen. For instance, certain electrolyte levels (like potassium) can still be measured, but results may be artificially elevated. Additionally, tests for lactate dehydrogenase (LDH) and aspartate aminotransferase (AST) can also be conducted, though clinicians must interpret results with caution due to the potential for altered values. It's essential to consult specific laboratory guidelines for the tests affected by hemolysis.
What is cerebrospinal fluid analysis?
The procedure to remove cerebrospinal fluid is called a lumbar puncture, or spinal tap, because the area of the spinal column used to obtain the sample is in the lumbar spine, or lower section of the back.
Could I be pregnant Lactating but negative home pregnancy test.?
It is possible to lactate during pregnancy (I had milk that spontaneously came months before my second child), though you would have to talk to your health care provider to know if this is what is happening with you.
How do you know you are preagnaut?
The most sure ways to know are to see a doctor or take a pregnancy test. Other than that, you will feel random mood swings, your breasts will increase in size and lactate, you will get morning sickness, and of course the baby growing will start to show after a couple of months.
What is the principle behind g6pd test?
The G6PD test measures the activity of glucose-6-phosphate dehydrogenase, an enzyme crucial for red blood cell health. This enzyme helps protect red blood cells from oxidative damage by facilitating the production of NADPH, which is vital for maintaining the integrity of cell membranes. A deficiency in G6PD can lead to hemolytic anemia, particularly when exposed to certain triggers like infections, certain foods, or medications. The test is often used to diagnose G6PD deficiency, especially in individuals with unexplained anemia or jaundice.
