LDH (lactate dehydrogenase) is an enzyme that is found in various tissues and organs of the body, including fluid such as pleural, pericardial or peritoneal fluid. LDH levels in fluid are typically measured to help diagnose and monitor certain medical conditions.
When this test is required
The test is typically ordered when a healthcare provider suspects the presence of an infection, inflammation, cancer, or other medical conditions that can cause fluid accumulation in a specific area of the body.
What the Test Detects
The test measures the level of LDH enzyme in the fluid sample. Elevated levels of LDH in the fluid may indicate a variety of medical conditions, including infections, inflammation, cancer, or other medical conditions that cause fluid accumulation.
Preparation for the Test
No special preparation is required for this test.
Sample Requirements
The test requires a sample of fluid to be collected from the pleural, pericardial or peritoneal area.
Additional Notes
LDH levels in fluid are just one tool used in the diagnosis and monitoring of medical conditions. Additional testing, imaging studies, and clinical evaluation may be necessary to fully assess and manage the patient’s condition.
