Details
Deficiency of Vitamin E may cause extensive neuropathy in young children and, in addition, 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.

This test checks for Vitamin E levels in the body. Vitamin E is crucial for nerve health. Low levels can lead to serious nerve damage in both children and adults. It's often seen in people with diseases that affect how nutrients are absorbed, like bowel disease, pancreatic disease, or chronic cholestasis. Other conditions that might cause Vitamin E deficiency include celiac disease, cystic fibrosis, and intestinal lymphangiectasia.
