APPLICATION:  Investigation of haemolysis in infants (especially premature); monitoring of children with severe, chronic fat malabsorption (especially chronic cholestasis) in whom a progressive cerebellar and sensory dysfunction may develop.  A role in the investigation of atherosclerosis in individual patients has not been established.

INTERPRETATION:  Low levels indicate deficiency, however, vitamin E is carried in plasma lipoproteins, and hyperlipidaemia may disguise an underlying deficiency, especially in patients with cholestasis.
