AB  - Established methods for quantitative analysis of fecal carbohydrates (CHO) are 
      time consuming, require unpopular sample handling, and are therefore rarely 
      performed. The aim of this study was to evaluate the efficiency, validity, and 
      practicability of near-infrared reflectance analysis (NIRA), compared with 
      standard methods for measurement of fecal CHO. Excretion of fecal CHO was cross- 
      validated spectrophotometrically with the anthrone method. Fecal CHO 
      concentrations ranged form 2.7 to 24.5 g/kg wet weight. Methods comparison showed 
      linear regression over the entire range of diagnostic relevance with a 
      correlation coefficient of 0.869 (S(y/x) +/- 0.31). Repeated measurements from 
      the same stool collections obviated the need for homogenization. These results 
      indicate that NIRA may be a new, reliable, and accurate test in the diagnosis of 
      CHO malabsorption.
