Additional Information

Use: Measurements of lactic acid are useful
in the diagnosis and treatment of lactic acidosis (abnormally high
acidity in the blood).  Typically, patients with lactic
acidosis and congestive heart failure or severe anemia show poor
tissue oxygenation (hypoxia).  Patients with lactic acidosis
and diabetes mellitus, renal failure or liver disease usually do
not show evidence of hypoxia.
