LDH serves as a non-specific but sensitive marker of tissue damage across multiple organ systems. It is an enzyme found in nearly all body tissues and released into the bloodstream when cells are damaged.
Diagnostic Value: Elevated LDH levels indicate tissue injury or disease affecting the heart, liver, lungs, muscles, or red blood cells.
Clinical Significance: LDH serves as a nonspecific but sensitive marker of cell damage, supporting diagnosis of hemolytic anemia, myocardial infarction, and liver disease.
Symptom Correlation: High LDH may be associated with fatigue, chest pain, jaundice, or muscle soreness depending on the affected organ.
Because it reflects cell integrity across multiple systems, LDH testing helps detect and monitor tissue damage and systemic disease activity.
