Riboflavin concentration in the blood of persons with symptoms of so-called riboflavin deficiency was investigated and the results were statistically examined. Further the symptoms important for the assessment of riboflavin deficiency were investigated and whether these results might be acceptable without considering sex or ages was examined. 1) In either sex, the riboflavin concentrations in the blood of deficient groups were significantly lower than those of healthy control groups (confidence limits 95%) 2) The riboflavin concentrations in the blood of women were lower than men, both in the cases of healthy and deficient groups. The difference in sex was significant in the case of school children (confidence limits 95%) 3) If classified by the symptoms, the groups which had eye-symptoms or glossitis had the lowest riboflavin concentrations. 4) For purpose of the clinical diagnosis of riboflavin deficiency, it is convenient and rational to know the presence of the eye-symptoms and glossitis.
