VITAMIN A (RETINOL)

The VITAMIN A (RETINOL) at‑home test measures circulating serum retinol — the active form of vitamin A — using a certified Dubai laboratory for analysis. This quantitative blood test evaluates vitamin A status, an essential nutrient for vision (particularly night vision), immune function, epithelial and skin health, and normal cell differentiation. Samples are collected conveniently at home (finger‑prick or venous as specified) and sent to the lab for precise measurement and reporting.

This test is useful for detecting deficiency or excess of vitamin A, guiding supplementation decisions, and monitoring treatment in at‑risk groups such as people with malabsorption, chronic liver disease, restrictive diets, or those on long‑term supplementation. Results can be influenced by recent dietary intake, inflammation, and lipid status, so interpretation should be performed by a healthcare professional in Dubai/UAE to ensure appropriate clinical action and safe use of supplements, especially in pregnancy.
