    Area of Science:

    • Clinical Chemistry
    • Laboratory Medicine
    • Analytical Chemistry

    Background:

    • The College of American Pathologists initiated a pilot survey program in 1976.
    • This program focused on evaluating urinary chemistry analytes.

    Purpose of the Study:

    • To assess the performance of laboratory assays for nine key urinary chemistry analytes.
    • To identify specific analytes with assay performance deficiencies.

    Main Methods:

    • A pilot survey was conducted involving over 230 laboratories.
    • Assay performance was evaluated using consensus evaluation criteria.

    Main Results:

    • Performance deficiencies were identified for amylase, 17-ketosteroids, and total protein assays.

  • Acceptable assay performance was observed for calcium, phosphorus, sodium, potassium, creatinine, and osmolality.

    • Conclusions:

    • The 1976 pilot survey highlighted areas needing improvement in urinary chemistry assay accuracy.
    • Further efforts are needed to enhance the reliability of specific urinary chemistry tests.
