Retinol-Binding Protein (RBP) is a versatile biomarker that not only helps in assessing vitamin A status, but also provides insights into nutritional health, diabetes risk, and renal function.
Assessing vitamin A status: The role of Retinol-Binding Protein
RBP is a carrier protein for vitamin A (retinol) in blood. RBP is synthesised and stored in the liver until it binds to retinol and enters circulation. It is cleared by renal filtration after retinol release, where it is almost completely reabsorbed by the proximal renal tubule.1,2 The concentration of RBP in circulation remains semi-constant in healthy individuals, though the levels can be altered in many conditions and disorders such as:
- Vitamin A deficiency
- Undernutrition
- Diabetes
- Renal dysfunction
