Summary Statement of Deficiencies D2016 SUCCESSFUL PARTICIPATION CFR(s): 493.803(a)(b)(c) (a) Each laboratory performing nonwaived testing must successfully participate in a proficiency testing program approved by CMS, if applicable, as described in subpart I of this part for each specialty, subspecialty, and analyte or test in which the laboratory is certified under CLIA. (b) Except as specified in paragraph (c) of this section, if a laboratory fails to participate successfully in proficiency testing for a given specialty, subspecialty, analyte or test, as defined in this section, or fails to take remedial action when an individual fails gynecologic cytology, CMS imposes sanctions, as specified in subpart R of this part. (c) If a laboratory fails to perform successfully in a CMS- approved proficiency testing program, for the initial unsuccessful performance, CMS may direct the laboratory to undertake training of its personnel or to obtain technical assistance, or both, rather than imposing alternative or principle sanctions except when one or more of the following conditions exists: (1) There is immediate jeopardy to patient health and safety. (2) The laboratory fails to provide CMS or a CMS agent with satisfactory evidence that it has taken steps to correct the problem identified by the unsuccessful proficiency testing performance. (3) The laboratory has a poor compliance history. This CONDITION is not met as evidenced by: Based on review of the federal report for unsuccessful proficiency testing (PT) results and review of the comparative evaluation reports from American Proficiency Institute, the laboratory failed to achieve satisfactory performance for hematocrit in two consecutive testing events resulting in unsuccessful PT participation (D2130). D2130 HEMATOLOGY CFR(s): 493.851(f) (f) Failure to achieve satisfactory performance for the same analyte in two consecutive Statement of Deficiencies (X1) Provider/Supplier/CLIA Identification Number (X3) Date Survey Completed Name of Provider or Supplier Street Address, City, State -- 1 of 2 -- events or two out of three consecutive testing events is unsuccessful performance. This STANDARD is not met as evidenced by: Based on review of the federal report for unsuccessful proficiency testing (PT) results and review of the comparative evaluation reports from American Proficiency Institute (API), the laboratory failed to achieve satisfactory performance for hematocrit in two consecutive testing events. Findings: 1. The laboratory received the following unacceptable results for hematocrit from API in two consecutive PT events: a. 40% in the 2024 3rd PT Event b. 40% in the 2025 1st PT Event D6000 MODERATE COMPLEXITY LABORATORY DIRECTOR CFR(s): 493.1403 The laboratory must have a director who meets the qualification requirements of 493. 1405 of this subpart and provides overall management and direction in accordance with 493.1407 of this subpart. This CONDITION is not met as evidenced by: Based on review of the federal report for unsuccessful proficiency testing results and review of the comparative evaluation report from American Proficiency Institute, the laboratory director failed to ensure an approved

Summary Statement of Deficiencies D2011 TESTING OF PROFICIENCY TESTING SAMPLES CFR(s): 493.801(b)(3) Laboratories that perform tests on proficiency testing samples must not engage in any inter-laboratory communications pertaining to the results of proficiency testing sample (s) until after the date by which the laboratory must report proficiency testing results to the program for the testing event in which the samples were sent. Laboratories with multiple testing sites or separate locations must not participate in any communications or discussions across sites/locations concerning proficiency testing sample results until after the date by which the laboratory must report proficiency testing results to the program. This STANDARD is not met as evidenced by: Based on review of written procedures, the hematology laboratory (CBC testing on the hematology analyzer) did not have written procedures to ensure proficiency test results were not compared between the Rockville office laboratory and the Germantown office laboratory prior to reporting results to the proficiency test provider for evaluation. Findings: 1. Proficiency test providers mail a set of unknown samples to laboratories for testing, the providers receive the test results and evaluate the laboratories accuracy. A proficiency test event occurs each time a shipment of unknown samples is received by the laboratory. 2. Testing staff rotate between the Rockville and Germantown office. For each proficiency test event, both offices receive the same proficiency testing samples from the same proficiency testing provider as each duplicate set of samples arrive in two separate boxes at the Rockville office before having one box of samples taken to the Germantown office for testing. 3. There is no written procedure to ensure that the results obtained from the two offices are not compared between the two laboratories prior to reporting to the proficiency test provider for scoring or evaluating performance, and that the same person does not perform the proficiency testing at both offices for the same test event. 4. If the laboratories cannot ensure that different people perform the proficiency testing for the Statement of Deficiencies (X1) Provider/Supplier/CLIA Identification Number (X3) Date Survey Completed Name of Provider or Supplier Street Address, City, State -- 1 of 2 -- Germantown and Rockville laboratories for a single proficiency test event, then the laboratory will need to use a different proficiency test provider for each location. D5421 ESTABLISHMENT AND VERIFICATION OF PERFORMANCE CFR(s): 493.1253(b)(1) Each laboratory that introduces an unmodified, FDA-cleared or approved test system must do the following before reporting patient test results: (1)(i) Demonstrate that it can obtain performance specifications comparable to those established by the manufacturer for the following performance characteristics: (1)(i)(A) Accuracy. (1)(i) (B) Precision. (1)(i)(C) Reportable range of test results for the test system. (1)(ii) Verify that the manufacturer's reference intervals (normal values) are appropriate for the laboratory's patient population. This STANDARD is not met as evidenced by: Based on record review and interview, the laboratory did not validate the current hematology CBC analyzer for accuracy. Findings: 1. In November 2023, the laboratory replaced the hematology (CBC) analyzer with another analyzer. 2. The validation studies did not include the testing data and summary used to determine and evaluate the accuracy of the current hematology analyzer. 3. This was confirmed during interview with testing person #1 at noon on the day of survey. D5783
