Validation and Stability of Retinol-Binding Protein: Evidence From Tanzania

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.

Examination of Venous and Capillary Blood Specimens for Assessment of Vitamin A Deficiency (Thailand Study)

This study provided the first evidence of the biological comparability between serum retinol levels estimated from venous blood and capillary blood. This critical observation provides empirical evidence that this important indicator of vitamin A status may be measured from capillary blood, which has important implications for nonclinical population-based research.
