Vitamin A details
What Vitamin A shows
Vitamin A is a fat-soluble vitamin essential for vision (particularly night vision), immune function, and skin and mucous membrane health. Deficiency, though uncommon in developed countries with varied diets, can occur with fat-malabsorption conditions or very restrictive diets, and can cause vision problems (including night blindness) and increased infection risk. Because vitamin A is fat-soluble and stored in the body, excessive intake — usually from high-dose supplementation rather than diet — can also build up to toxic levels over time, causing its own set of symptoms, so this test can be used to evaluate either deficiency or suspected excess.

Tests that include Vitamin A
Vitamin A (Retinol) is a fat-soluble vitamin crucial for vision, immune function, and cellular growth. It is commonly measured to assess nutritional status, especially in cases of malabsorption, poor diet, or symptoms like night blindness and dry skin.
- Vitamin A Measures vitamin A, important for vision, immune function, and skin health.

- Vitamin A Measures vitamin A, important for vision, immune function, and skin health.
This test measures the levels of various essential micronutrients and antioxidants in the body, which are crucial for maintaining health and preventing diseases. Antioxidants help protect the body from damage caused by free radicals and are important for immune function, skin health, and overall well-being.
- Coenzyme Q10 (CoQ10) An antioxidant compound your cells use to produce energy. Tested to assess CoQ10 status, especially in people on statin medications, which can lower natural levels.
- Vitamin A Measures vitamin A, important for vision, immune function, and skin health.
- Vitamin C An antioxidant vitamin important for immune function, collagen production, and iron absorption.
- Vitamin E, Alpha-Tocopherol The most active form of vitamin E in the body, an antioxidant that protects cells from damage. Used to assess vitamin E status.
- Vitamin E, Beta Gamma Tocopherol Measures beta- and gamma-tocopherol, forms of vitamin E found mainly in vegetable oils, nuts and seeds, as part of a vitamin E assessment.
