Lactate Dehydrogenase
LDH
Description
"Lactate Dehydrogenase" (LDH) test checks levels of LDH, an enzyme released when tissues are damaged. Though not specific to the liver, elevated LDH can support the diagnosis of liver disease, hemolytic anemia, or certain cancers. It’s often used when unexplained inflammation, fatigue, or pain is present. Doctors use this test alongside others to identify organ damage and monitor healing. Regular LDH testing helps track recovery, assess treatment effectiveness, and support long-term organ health and recovery status.

Results That Differ From The Norm (Direct and Indirect Causes)
Increased levels may indicate:
Autoimmune hemolytic anemia (Immune system attacks red blood cells)
Bacterial infections
Cancer
Cirrhosis (Chronic liver damage)
Dermatomyositis (Inflammatory muscle and skin disease)
Hepatitis (Inflammation of the liver)
Hemodialysis (Renal replacement therapy)
...
Key Reasons For Testing
Tissue Damage Detection: Elevated LDH indicates tissue damage, aiding diagnoses like myocardial infarction or liver disease.
Cancer Diagnosis and Monitoring: Acts as a tumor marker for malignancy diagnosis, prognosis, and treatment evaluation.
Assessment of Hemolysis: Detects hemolysis in conditions like anemia or transfusion reactions.
Prognostic Marker: Predicts outcomes in critically ill patients with conditions such as sepsis or multiorgan failure.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
