Lactate Dehydrogenase, Serum or Plasma
Also known as: LDH
Use
This test is used to assess a variety of pathological conditions, primarily in hematology and oncology. Lactate dehydrogenase (LDH) levels can indicate tissue damage and are often elevated in certain diseases such as anemia, myocardial infarction, or cancers. Monitoring LDH levels can help in the diagnosis and treatment monitoring of these conditions.
Special Instructions
Ensure that serum or plasma is separated from the cells as soon as possible or within 2 hours of collection. Use ARUP Standard Transport Tube for transportation of samples.
Limitations
This assay may not accurately reflect the physiological status if specimen handling and storage guidelines are not adhered to. Specimens collected in EDTA, potassium oxalate, or sodium fluoride are not acceptable, as they may interfere with the accuracy of the results. Hemolyzed samples, due to cell lysis, can cause falsely elevated results.
