Summary Statement of Deficiencies D2121 HEMATOLOGY CFR(s): 493.851(a) (a) Failure to attain a score of at least 80 percent of acceptable responses for each analyte in each testing event is unsatisfactory analyte performance for the testing event. This STANDARD is not met as evidenced by: Based on record review and staff interview, the laboratory failed to obtain a proficiency testing (PT) score of at least 80 percent for White Blood Cell (WBC) differential testing for Event 2 of 2025 in the specialty of Hematology. Findings include: 1. Record review on 7/23/2025 of the Center of Medicare and Medicaid Services (CMS), generated "Casper Report 0155D" revealed the laboratory obtained an unsatisfactory PT score of 40% for WBC Differential analyte, Event 2, 2025. 2. Record review on 7/23/2025 of the College of American Pathologist (CAP), "Original Evaluation" report for "FH16-B 2025 Hematology Auto Differentials, FH-16" revealed following unacceptable results for the WBC Differentials: a."Test: Neut /Gran % : Specimens FH16-06, FH16-07, FH16-09, and FH16-10." b. "Test: Neut /Gran Absolute: Specimens FH16-06, FH16-07, FH16-08, FH16-09, and FH16-10." c. "Test: Lymphs %: Specimens FH16-06, FH16-07, and FH16-10." d. "Test: Lymphs Absolute: Specimens FH16-07." e. "CMS performance Summary for Analytes Regulated Under the Clinical Laboratory Improvement Amendments of 1998" revealed the following: i. "Regulated Analyte: WBC Differential" ii. "Proficiency Event: 2, 2025" iii. "Test Event: FH16-B" iv. "Score: 2/5; 40 %" v. "Performance Interpretation: Unsatisfactory" 3. Staff interview on 7/23/2025 at 11:20 AM with the Technical Consultant (TC) confirmed the above findings. The TC further stated that the laboratory performed the PT using the "QC mode" as advised by the Beckman coulter technical services and obtained an unsatisfactory score. He/she further 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 -- commented that the laboratory has stopped reporting the WBC differentials on patient samples as of 06/02/2025. 4. The laboratory performs 4150 complete blood counts annually in the specialty of Hematology.
