Summary Statement of Deficiencies D0000 The Centers for Medicare & Medicaid Services (CMS) conducted an unannounced Clinical Laboratory Improvement Amendments (CLIA) recertification survey at Laboratorio Clnico Pajuil on May 8, 2026. The laboratory was surveyed under 42 CFR part 493 CLIA requirements. The following standard level deficiencies were found during the unannounced routine CLIA recertification survey ending on May 8, 2026. D2010 TESTING OF PROFICIENCY TESTING SAMPLES CFR(s): 493.801(b)(2) (b)(2) The laboratory must test samples the same number of times that it routinely tests patient samples. This STANDARD is not met as evidenced by: Based on review of the routine chemistry proficiency samples test results for the first testing event of year 2026, proficiency testing (PT) written procedures and interview with the laboratory director on May 8, 2026, at 8:15 a.m., the laboratory failed to test routine chemistry PT samples in the same number of times that it routinely tested patient specimens. The laboratory processed the routine chemistry PT samples on February 4, 2026, February 5, 2026, and February 6, 2026. The findings include: 1. On May 8, 2026, at 8:15 a.m., the routine chemistry PT records for the first testing event of 2026 were reviewed. 2. On May 8, 2026, at 8:20 a.m., review of the routine chemistry PT samples test results showed that the laboratory processed each PT sample in triplicate, as follows: a. PT sample ID PROF #1 was processed on February 4, 2026, at 3:04 p.m.; February 5, 2026, at 2:22 p.m.; and February 6, 2026, at 11:42 a. m. b.
