This document assesses the correspondence between retinol and retinol-binding protein (RBP), as well as the stability of RBP subjected to varying temperature conditions over time, the effect of light, and the feasibility of using dried blood spots. The assessment is part of a larger project examining the use of the RBP enzyme immunoassay (RBP-EIA) to test for vitamin A deficiency.
