For Elevated Results: 

Rarely, lactate dehydrogenase might be falsely elevated due to the presence of immunoglobulin-LD complex.  Samples from patients with unexpected high levels of lactate dehydrogenase should be investigated for the presence of immunoglobulin-complexed enzyme as a cause for such results.
