Why labs are adding RBP now
RBP is particularly relevant in nutritional screening, monitoring of kidney tubular function, and metabolic disease evaluation:
-
Growing focus on nutritional assessment
-
Increased metabolic disease burden
-
Need for rapid, scalable biomarkers

Why RBP matters: A multi-purpose biomarker
Retinol-Binding Protein (RBP) is a key transport protein for vitamin A (retinol) in the bloodstream. Synthesized in the liver, RBP binds to retinol before entering circulation. After retinol delivery, RBP is filtered by the kidneys and nearly fully reabsorbed by the proximal renal tubule.1,2
RBP levels are relatively stable in healthy individuals, but fluctuations may signal underlying health conditions, including:
- Vitamin A deficiency
- Undernutrition
- Diabetes
- Renal dysfunction
Gentian Retinol-Binding Protein Immunoassay
Gentian’s turbidimetric RBP assay is designed for automated, high-throughput clinical chemistry analysers, enabling seamless integration into routine workflows.
Whether for routine testing or research applications, Gentian’s assay fits seamlessly into diverse laboratory workflows:
- Instrument independent
- FDA Exempt
- CE-marked, UKCA-marked
The assay boasts high precision with a coefficient of variation (CV) below 5% and a limit of quantification (LoQ) at 7.81 mg/L. The measuring range extends from 7.8 to 139 mg/L, making it suitable for various clinical needs.
