[Normal serum concentration of retinol transport protein (RBP) measured by an immunonephelometric method]

The authors give serum retinol binding protein (RBP) normal values, established by immunonephelometry, for two healthy populations in their hospital laboratory. The mean values for men's and women's group are significantly different. They note for women's group with estroprogestative drugs a higher mean value. Relations between retinol and RBP metabolism are known. RBP values give a good estimation of retinal reserves in patients.
