Abstract
Objective: To determine the performance of a portable fluorometer for measuring serum retinol (SR) concentration. Design and methods: Serum samples were obtained from 75 factory worker women and 143 school children. SR concentration was quantified using a portable fluorometer ('CRAFTi') and HPLC analysis. Results: SR by HPLC (1.23. ±. 0.43. μmol/L) and CRAFTi (1.16. ±. 0.46. μmol/L) was significantly correlated. Sensitivity and specificity were 85.3% and 78.0% (cutoff of 1.05. μmol/L). Kappa statistics showed moderate agreement. Conclusions: CRAFTi portable fluorometer is a promising field-friendly tool for screening vitamin A deficiency. © 2011 The Canadian Society of Clinical Chemists.
