Description
Why It’s Done:
• To diagnose vitamin E deficiency, especially in people with fat malabsorption disorders (e.g., cystic fibrosis, Crohn’s disease).
• To monitor individuals on long-term parenteral nutrition or restricted diets.
• To evaluate symptoms like muscle weakness, vision problems, poor coordination, or neurological issues.
• Occasionally used to check for vitamin E toxicity from over-supplementation.
Preparation:
• Fasting may be required (typically 8–12 hours) to ensure accurate results. Follow your healthcare provider’s instructions.
