Description: The Lactate Dehydrogenase (LDH) Blood Test is a simple, reliable laboratory test used to evaluate cell damage, tissue injury, and overall metabolic health. LDH is an enzyme found in nearly all body tissues—when cells are damaged, LDH levels rise. This makes the test useful for identifying a wide range of conditions involving the heart, liver, muscles, lungs, and blood.
This test reports your total LDH level, which can help identify:
  • Tissue damage or inflammation
  • Liver disease
  • Muscle injury
  • Hemolytic anemia
  • Certain cancers
  • Lung or kidney disorders
  • LDH is a non-specific marker, meaning it doesn’t diagnose a condition by itself—but it provides important clues your provider can use alongside symptoms and other tests.
