    Establishing age and sex-specific glucose reference limits is crucial for accurate diagnosis, especially with borderline results. This study reveals a linear decline in glucose tolerance with age, impacting diagnostic clarity.

    Area of Science:

    • Clinical Chemistry
    • Endocrinology
    • Gerontology

    Background:

    • Interpreting borderline glucose levels without symptoms poses diagnostic challenges.
    • Accurate reference ranges are essential for reliable clinical decision-making.

    Purpose of the Study:

    • To establish age- and sex-specific reference limits for post-prandial plasma glucose.
    • To investigate the relationship between age, sex, and glucose tolerance.

    Main Methods:

    • Analysis of 28,581 post-prandial plasma glucose estimations.
    • Application of regression analysis to determine 97.5th percentile reference limits.
    • Consideration of age, sex, and time of specimen collection.

    Main Results:

    Related Experiment Videos

  • A significant linear relationship was identified between increasing age and decreased glucose tolerance in both sexes.
  • Glucose tolerance was influenced by the time of day when specimens were collected.
  • No evidence of bimodal distribution in glucose tolerance was observed.
  • Conclusions:

    • Age- and sex-specific reference limits are necessary for accurate glucose assessment.
    • The decline in carbohydrate tolerance with advancing age appears to be a population-wide phenomenon.
    • These findings aid in the interpretation of borderline glucose results and improve diagnostic accuracy.
