Discover your vitamin A levels with a vitamin A blood test.

Optimize your nutrition and overall well-being with our vitamin A blood test.

 

Vitamin A is a nutrient that’s vital for maintaining healthy vision, promoting healthy skin and supporting the immune system. It plays a role in cell growth, especially in the formation and maintenance of healthy teeth, bones, soft tissues and mucous membranes. Vitamin A is also important for reproductive health and maintenance of the heart, lungs, eyes and other organs.

 

Our trusted vitamin A test measures retinol, the active form of vitamin A in the body. A vitamin A deficiency may be due to inadequate vitamin A in your diet or a health condition that interferes with vitamin absorption. Symptoms may include dry eyes, difficulty seeing in low light settings at night, skin conditions, and a weakened immune system.  This test can also identify too much vitamin A in the body.

What's Tested
  • Vitamin A

    The Vitamin A Test measures the amount of vitamin A (retinol) in your blood. This fat-soluble vitamin is essential for maintaining healthy vision, supporting cell growth, metabolism, immune function, and proper functioning of the heart, lungs, bones, and other organs. Low levels may lead to fatigue, vision problems, dry/scaly and/or itchy skin, and potentially increased risk of infections. Vitamin A is naturally found in foods like carrots, sweet potatoes, leafy green vegetables, and dairy products, making it important to include these in your diet.

FAQ

  • A vitamin A blood test helps assess your vitamin A level, which plays a key role in maintaining healthy vision, skin and immune function. Individuals with restrictive or limited diets or certain conditions that interfere with normal digestion such as cystic fibrosis, Crohn’s disease, ulcerative colitis, celiac disease or prior bariatric surgery can develop vitamin A malabsorption.  

     

    For those experiencing low vitamin A symptoms such as dry eyes, dry skin, difficulty seeing at night, and increased infections, testing can help you find out what your vitamin A levels are, to support your health. 

  • The best way to prevent vitamin A deficiency and to improve vitamin A levels is by eating a well-balanced diet and incorporating foods high in vitamin A.

     

    Recommendations based on the Dietary Guidelines for Americans include:

    • Eating a variety of vegetables, fruits, whole grains, fat-free or low-fat milk and milk products, and oils.
    • Eating a variety of protein foods, including seafood, lean meats and poultry, eggs, legumes (beans and peas), nuts, seeds, and soy products. Beef liver also contains high amounts of vitamin A.
    • Limiting foods and beverages higher in added sugars, saturated fat, and sodium.
    • Limiting alcoholic beverages.
    • If dietary changes are not sufficient, or if you have increased needs, a vitamin A supplement may be recommended by your healthcare provider. It’s important to consult with your provider before determining if supplementation is necessary, as too much vitamin A can also have negative health effects.
