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. This STANDARD is not met as evidenced by: Based on surveyor review of the laboratory's new instrumentation, observation of instrumentation in the laboratory, interview with the laboratory manager, and lack of documentation the laboratory failed to have a system that twice annually evaluates the relationship between test results using different instruments for sodium, potassium, chloride, glucose, blood urea nitrogen, carbon dioxide, and creatinine since the installment of the new chemistry instrument on September 2023. Findings are: 1. Review of the laboratory's new instrumentation revealed the laboratory began using a new chemistry analyzer on September 2023. 2. Observation of the laboratory's instrumentation revealed an iSTAT instrument in the laboratory. 3. Interview with the laboratory manager on 5/21/2025 at 12:20 PM, confirmed the laboratory performs chemistry testing for sodium, potassium, chloride, glucose, blood urea nitrogen, carbon dioxide, and creatinine on the iSTAT analyzer and on the new chemistry analyzer. 4. Interview with the laboratory manager on 5/21/2025 at 12:20 PM, and lack of documentation confirmed the laboratory did not evaluate the relationship between the two instruments for sodium, potassium, chloride, glucose, blood urea nitrogen, carbon dioxide, and creatinine since the new chemistry instrument was installed on September 2023. 5. Interview with the laboratory manager on 5/21/2025 at 12:20 PM confirmed thirteen patients were tested on the iSTAT analyzer since the new chemistry instrument was installed on September 2023.
