Context:Vitamin E is a powerful antioxidant and plays an important role in human reproduction. However, micronutrient
deficiency is a major public health problem, particularly in developing
countries. This study aimed to establish reference intervals (RIs) for vitamin E in black
Congolese people of childbearing age using an ELISA method to provide a
reference for clinically assessing vitamin E status. Methods: A total of
127 healthy people between the ages of 20 and 42 who underwent check-ups were
randomly selected for the study. ELISA method measured the level of vitamin E.
The effect of gender on vitamin E level was assessed, and RI was established using a
parametric approach. Results: Women showed significantly higher levels
of vitamin E than men (p = 0.01). The RI of vitamin E in people of childbearing
age was 3.71 to 13.72, 4.52 to 14.64, and 4.17 to 13.52 mg/L, respectively, for
the whole population, women and men. Conclusion: Using an ELISA method, this study established RI for vitamin E in the black Congolese population of childbearing age. We also found that women had significantly higher
vitamin E levels than men. The results could provide a scientific basis for
interpreting vitamin status in people of childbearing age in our setting.
