What is an LDH test?
An LDH test measures the amount of LDH in the blood and it is done to look for the tissue damage in the body.
Lactate dehydrogenase (LD or LDH) is an enzyme present in almost every cell of the body including the blood, muscles, brain, kidneys, and pancreas. This enzyme converts sugar into energy. It is released from the cells into the fluid portion of the blood (plasma or serum) when the cells are damaged or destroyed. Sometimes it can also be found in the cerebrospinal fluid when you have bacterial meningitis (inflammation of the brain and spinal cord membranes).
Normal LDH levels
LDH levels will vary based on age. Lactate Dehydrogenase normal range in the blood is given below.
- 0 to 10 days – 290 to 2000 U/L (units per liter)
- 10 days to 2 yrs – 180 to 430 U/L
- 2 to 12 yrs – 110 to 295 U/L
- Above 12 yrs – 100 to 190 U/L
Why is an LDH test done?
Your physician will order an LDH test if your symptoms indicate that you might have tissue damage (the symptoms will vary based on the type of damage) or for the following reasons.
- To find out if you have tissue damage
- To monitor disorders that can cause tissue damage such as anemia, liver disease, lung disease, and other types of infection
- To check the effectiveness of ongoing treatment for cancer
How is the LDH test performed?
LDH test is a simple blood test. During this test, a lab technician or a phlebotomist will cleanse the area to be injected with an antiseptic and wrap an elastic band around the upper arm to make the vein visible and pool with blood. He/she then injects a needle to draw a sample of blood and collects the blood sample in a vial (a small glass container) or a test tube. After the blood is drawn, he/she covers the injected area with a band-aid or a cotton ball to stop bleeding. The collected blood sample is then sent to the lab for further analysis.
It takes less than 5 to 10 minutes to perform this test.
Sometimes, LDH is measured in other body fluids such as fluids in the spinal cord, lungs or abdomen. Your healthcare practitioner will provide more information regarding the procedure of taking the sample of these body fluids.
Is there any preparation required before the test?
There is no special preparation required for the LDH blood test.
Are there any risks to the test?
There are no possible risks or complications in the LDH test. But sometimes after the blood sample is drawn, you might feel dizziness, slight pain, bruise, soreness, or redness in the injected area for a very little period.
What does the LDH test result mean?
Elevated LDH levels
High LDH levels can indicate some form of tissue damage. Your physician might order more tests to find out the location, type, and severity of the tissue damage.
Low LDH levels
Generally, low and normal LDH levels do not indicate any kind of infection or defect in the body. LDH is a protein that naturally appears throughout the body in a small-scale ratio. Sometimes, low levels of LDH may be caused due to the consumption of vitamin C in large amounts.
The LDH test can be done in any of the following locations across the U.S. by visiting the nearest lab. To know the LDH test cost, refer to the first section of the article.
