Lactic Acid Dehydrogenase LDH Blood Test

* This is not a home test kit. You will need to visit a local lab for testing.

Also Known As

Lactic dehydrogenase, LD Test

The Purpose of an LDH Test

Everyone has lactic acid dehydrogenase (LDH) in their bodies, and that’s a good thing because this enzyme found in the tissues of your body is necessary for creating the energy you need for daily life. What isn’t a good thing: high levels of LDH, which likely means that you are suffering from tissue damage. And that’s critical because these affected tissues can damage major organs such as the heart, brain, liver, and lungs. An LDH lab test ensures you have normal levels for optimal health.

What Does the LD Lab Measure?

LD testing checks your levels through a simple blood draw. These levels are measured in units per liter (U/L).

Who Should Take a Blood Test for LDH?

Your physician may recommend this test to help diagnose or monitor conditions such as:

  • Heart attack
  • Pancreatitis
  • Kidney, lung, or liver disease
  • Anemia
  • Muscular dystrophy
  • Viral infections such as meningitis or HIV
  • Certain cancers including leukemia or multiple myeloma

LD Blood Work Preparation

No special preparation is required for the LDH blood test.

LDH Test Results

Normal test results are different for men and women. Men’s LDH levels should fall between 135 and 225 U/L; women’s should range from 135 to 214 U/L. If your LDH test results are above the norm, you will probably undergo further testing, depending on your symptoms and the disease you may have.
