Specimen Requirements

Container/Tube:

Preferred: Pleural, peritoneal (ascites, pancreatic), pericardial and synovial fluid

Acceptable: Other fluid types including CSF should be approved by the supervisor

              submitted for other testing.

Reference Values

No established reference values
Note: LD activity in fluids from areas near or adjacent to malignancies is often higher than serum LD, whereas the opposite is true for fluids bathing healthy tissues.

Day(s) Test Set Up

Monday through Sunday

Useful For

Elevated serum levels of LDH have been observed in a variety of disease states. The highest levels are seen in patients with megaloblastic anemia, disseminated carcinoma and shock. Moderate increases occur in muscular disorders, nephrotic syndrome and cirrhosis. Mild increases in LDH activity have been reported in cases of myocardial or pulmonary infarction, leukemia, hemolytic anemia and non-viral hepatitis.

Methodology

Rate Reaction, IFCC-standardized

Reflex Information:

When #FLDH Lactate Dehydrogenase (LDH), Body Fluid is ordered (other than spinal fluid), a #LDH Lactate Dehydrogenase (LD), Plasma or Serum will also be done and the ratio calculated.
