Fragen und Antworten zu LDH - Laktatdehydrogenase
What is the respective laboratory value?
LDH is an enzyme that is present in almost all body cells and is involved in energy production. The laboratory value measures the concentration of LDH in the blood and is used to assess cell damage or tissue destruction.
For whom is such a test to be considered?
A LDH test is recommended for: • Patients with suspected tissue damage (e.g. heart attack, tumors, hemolysis) • People with symptoms such as unexplained fatigue, weakness or pain • Monitoring of patients with chronic diseases such as cancer or liver diseases • Diagnosis and progress control of blood disorders such as hemolytic anemia
What is it used for?
The test serves to diagnose cell or tissue damage and is often used to monitor tumor diseases, blood diseases or liver function disorders.
What can be inferred from that?
A high LDH value indicates: • Cell destruction in tissue damage (e.g. heart attack, stroke) • Hemolytic anemias (breakdown of red blood cells) • Tumor diseases with high cell division A low LDH value has no clinical significance. Symptoms with elevated LDH can include: • Pain or swelling with tissue damage • Fatigue or weakness in blood diseases
What is the ideal time for a test?
The testing can be carried out at any time of the day and is independent of food intake.
Particularly interesting?
• LDH alone is non-specific; the value should be interpreted in the context of other parameters. • LDH can be broken down into five isoenzymes, which provide specific information about the origin of the tissue damage. • Muscle exertion or blood samples with severe hemolysis can falsely increase LDH values.
