[Usual values of serum vitamin A using a modified fluorimetric method].

We report a fluorimetric technique for the determination of serum vitamin A. The critical study of this micromethod included trials of repeatability, inter-series reproducibility and an evaluation of its accuracy. It was compared with a method using high performance liquid chromatography followed by detection with UV spectrophotometry. Normal values were established for adults. The variations according to age were determined for children between the ages of 10 months and 15 years.
