Abstract
Summary
The assay of erythrocyte glutathione reductase (EGR) used to assess the riboflavin nutritional status has been modified to increase its utility.
The levels of EGR in cord blood are significantly higher than those in the blood of well-nourished pregnant women at term.
In both maternal and cord blood the activity coefficients (AC) were near 1, indicating that the EGR in both was saturated with FAD. This method to determine riboflavin deficiency can be applied to both pregnant women and newborns, and is not affected by increased reticulocytes.
