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.

- Vitamin E, Beta Gamma Tocopherol
Estimated days for results: Results should be available in 2 - 5 business days after the sample is collected
This test checks for Vitamin E levels in the body, which is crucial for nerve health. A lack of Vitamin E can lead to serious nerve damage in both children and adults. It's often caused by problems with absorbing nutrients due to conditions like bowel disease, pancreatic disease, chronic cholestasis, celiac disease, cystic fibrosis, or intestinal lymphangiectasia.
