Vitamin A Test

Vitamin A is a fat-soluble vitamin that plays a critical role in maintaining healthy vision, supporting the immune system, promoting healthy skin, and ensuring normal growth and cellular function. The ICare Vitamin A Test measures the level of vitamin A in your blood to help identify deficiencies or, less commonly, excessive levels that may affect your health.

Although vitamin A deficiency is uncommon in many developed countries, it can occur due to poor nutrition, digestive disorders, liver disease, or conditions that affect fat absorption. Excessive vitamin A intake, particularly from supplements, can also lead to health concerns. This test provides valuable information to help you and your healthcare provider determine whether your vitamin A levels are within a healthy range.

With ICare's concierge mobile laboratory services, advanced nutritional testing is delivered directly to your home, office, or preferred location, making preventive healthcare more convenient than ever.
