Summary Statement of Deficiencies D5775 COMPARISON OF TEST RESULTS CFR(s): 493.1281(a)(c) (a) If a laboratory performs the same test using different methodologies or instruments, or performs the same test at multiple testing sites, the laboratory must have a system that twice a year evaluates and defines the relationship between test results using the different methodologies, instruments, or testing sites. (c) The laboratory must document all test result comparison activities. This STANDARD is not met as evidenced by: Based on observation of the laboratory, document request, patient final test reports and staff interview, the laboratory failed to perform twice a year comparison of results between automated and manual white blood cell (WBC) differential 2021, 2022, and 2023. The findings include: 1. Observation of the laboratory on 03/15/23 at 8:15 a.m. revealed a Sysmex XP 300 (serial #B3616) in use for performing automated WBC differential and a microscope in use for performing manual WBC differential. 2. Request made to the technical consultant 03/15/23 at 11 a.m. for documentation of comparisons between the two WBC differential methods revealed no documentation was present. The technical consultant stated they do not perform formal comparisons between the two methods. 3. Review of randomly selected patient reports revealed the laboratory performed both automated WBC differential and manual WBC differential (MRNs 9176538, 4926556, 99700577, 100436510, 1040302) in 2021, 2022, and 2023. 4. Interview with the lead testing person and technical consultant on 03/15/23 at 12:30 p.m. confirmed the laboratory performs both automated and manual WBC differential and did not perform comparisons between the two methods twice a year in 2021, 2022, and 2023.
