Order this Vitamin E Serum test to measure vitamin E levels in the blood to screen for a deficiency. Vitamin E, often referred to as tocopherol or alpha-tocopherol, is an essential vitamin important for several body functions. For example, vitamin E helps your nerves and muscles work well, prevents blood clots, and boosts the immune system. In addition, vitamin E has antioxidant properties, which protect cells from damage.
Foods that naturally contain the most amount of vitamin E include:
- Leafy green vegetables (Swiss chard, turnips, and mustards)
- Vegetable oils
While a vitamin E deficiency is rare, it is most often the result of underlying health conditions that cause the malabsorption of nutrients. These include:
- Crohn's disease
- Liver disease
- Cystic fibrosis
- Rare genetic disorders
A diet extremely low in fat may also cause a vitamin E deficiency.
Signs or symptoms of a vitamin E deficiency include:
- Muscle weakness
- Slow reflexes
- Difficulty standing or walking
- Vision impairment or blindness
In addition to screening for a deficiency, a Vitamin E Serum test can be used to evaluate the vitamin E levels of premature babies at a higher risk of vitamin E deficiency and to determine if individuals are getting an excessive amount of vitamin E. Similar to a vitamin E deficiency, excessive levels of vitamin E in the blood are also rare. Abnormally high levels of vitamin E are usually caused by overconsumption of dietary supplements. Left untreated, individuals with excessive vitamin E levels can experience serious health problems, including an increased risk of heart disease (stroke).
