Lactate dehydrogenase (LDH)

Category Biochemistry
Test background

LDH is ubiquitous throughout the body and exists in several isoforms which are nominally localised to certain tissue types. Release into the vasculature typically correlates with tissue injury and is proportional to the degree of insult. Elevations of serum LDH may be observed in kidney and liver disease, haemolytic anaemia, pancreatitis, CVA and pulmonary and intestinal infarction.

Clinical Indications

Monitoring of established pancreatitis
Diagnosis and management of haemolytic and pernicious anaemia
