    Study Notes

    Proficiency Testing

    • Proficiency testing is involved in external quality control
    • Internal QC is performed by lab personnel using control materials of known values
    • Control material values are assessed using Levy-Jennings control charts and Westgard multirules
    • External QC is performed when samples are submitted to an external agency
    • Results are submitted to the agency for assessment
    • This type of assessment is known as proficiency testing
    • It is required by federal regulations for all laboratories providing results for human diagnosis and/or treatment
