    Specimen mix-up is a frequent and serious laboratory error. A new multivariate delta check method effectively detects these errors by analyzing test result discrepancies, improving laboratory accuracy.

    Area of Science:

    • Clinical Chemistry
    • Laboratory Medicine
    • Medical Diagnostics

    Background:

    • Specimen mix-up is the most frequent and serious laboratory error.
    • Such errors are often detected by large discrepancies between sequential test results.

    Purpose of the Study:

    • To present a novel method for detecting specimen mix-up.
    • To improve the accuracy and reliability of laboratory testing.

    Main Methods:

    • Extension of the traditional delta check method.
    • Introduction of the "multivariate delta check" method.
    • Analysis of discrepancies between sequential test results.

    Main Results:

    • The multivariate delta check method was developed.
