    Summary

    Newly developed aliquot cups accurately measure 24-hour urine sodium and potassium excretion. However, significant daily variations in healthy volunteers suggest at least five days of urine collection are needed to estimate daily intake.

    Area of Science:

    • Clinical chemistry
    • Nutritional science
    • Urine analysis

    Background:

    • Accurate measurement of daily sodium and potassium intake is crucial for health monitoring.
    • Traditional 24-hour urine collection methods can be cumbersome.
    • A novel tool, 'aliquot cups,' was developed for improved urine sample collection.

    Purpose of the Study:

    • To evaluate the utility and accuracy of aliquot cups for 24-hour urine sodium and potassium estimation.
    • To assess the variability of daily sodium and potassium excretion in healthy individuals.

    Main Methods:

    • Five healthy volunteers participated in the study.
    • 24-hour urine samples were collected daily for 31 consecutive days using aliquot cups.
    • Urinary sodium and potassium concentrations were analyzed.

    Main Results:

    • Aliquot cups demonstrated sufficient accuracy and usefulness for estimating 24-hour urine sodium and potassium excretion.
    • A considerable degree of both intra-individual and inter-individual variation in daily excretion was observed.
    • Data indicated substantial day-to-day fluctuations in electrolyte excretion.

    Conclusions:

    • The aliquot cup is a viable tool for assessing 24-hour urine sodium and potassium levels.
    • To reliably estimate daily intake, a minimum of five consecutive days of urine collection is recommended due to high variability.
    • Further research may explore the implications of this variability in different populations.
