Test Comments:
Vitamin E nutritional status should be evaluated along with serum lipids, since Vitamin E/lipid ratio gives a more accurate assessment of Vitamin E status than single serum Vitamin E.
Methodology:
HPLC
Clinical Significance:
Deficiency of vitamin E may cause extensive neuropathy in young children and, in additon, is suspect as a possible cause of motor and sensory neuropathy in older children and in adults. One likely cause of vitamin E deficiency is intestinal malabsorption, resulting from bowel disease, pancreatic disease, or chronic cholestasis.
Other causes of malabsorption of vitamin E include celiac disease, cystic fibrosis, and intestinal lymphangiectasia.
