Details

This panel measures lactate dehydrogenase isoenzymes. Lactate dehydrogenase (LD) is an enzyme found in almost all of the body's cells; elevated levels of this enzyme can be used as a general marker of cell injury. LD isoenzymes are used to determine the source of elevated LDH activity, as each isoenzyme tends to be concentrated in specific body tissues.

  • LD3
  • LD4
  • LD5
  • Lactate Dehydrogenase (LDH)

Estimated days for results: Results should arrive 3 - 6 business days after the lab receives samples.
