This blood test evaluates vitamin A (retinol) levels to check for deficiency. Vitamin A plays an important role in the formation of rhodopsin, a light-sensitive pigment in the eye, and it also supports vision, immune function, and skin health. The test may be ordered when a provider suspects a deficiency related to poor diet, fat malabsorption, or liver conditions, or when symptoms such as night vision problems are being evaluated. Because vitamin A is fat-soluble and stored in the body, results are interpreted carefully with other findings.

• People with suspected night vision problems or eye changes
• Individuals with fat malabsorption or liver conditions
• People with very restricted diets or malnutrition
• Those being assessed with a broader nutritional panel

• Vitamin A (retinol) Measures the level of this fat-soluble vitamin in the blood.

• Fasting may be requested before the draw.
• Tell the collector about vitamin supplements you take.
• Follow any instructions provided for your specific panel.

A low vitamin A level may suggest deficiency, which can relate to diet, fat absorption, or liver function, while a high level may occur with excessive supplementation. Because vitamin A is stored in the body and toxicity is possible with excess intake, results should be interpreted by a provider. Discuss them with a healthcare professional before changing anything.
