Summary:
Summary Statement of Deficiencies D3031 RETENTION REQUIREMENTS CFR(s): 493.1105(a)(3) Analytic systems records. Retain quality control and patient test records (including instrument printouts, if applicable) and records documenting all analytic systems activities specified in 493.1252 through 493.1289 for at least 2 years. This STANDARD is not met as evidenced by: Based on the lack of records and interview with the laboratory director and technical consultant on 5/28/19, the laboratory failed to retain quality control records of their prothrombin time/ INR controls for at least 2 years. Findings included: a. The laboratory tested two levels of control material each month for the prothrombin time/ INR tests. Their printout for prothrombin/INR control levels showed that control level 1 lot# 281097 and control level 2 lot# 291096 were run on 4/5/19. At the time of the survey, the manufacturer's assay information was not available for these two controls. b. The laboratory tested and reported prothrombin time and INR test results on approximately 36 patients a year. D5439 CALIBRATION AND CALIBRATION VERIFICATION CFR(s): 493.1255(b) Unless otherwise specified in this subpart, for each applicable test system the laboratory must do the following: Perform and document calibration verification procedure - (b)(1) Following the manufacturer's calibration verification instructions; (b)(2) Using the criteria verified or established by the laboratory under 493.1253(b)(3) -- (b)(2)(i) Including the number, type, and concentration of the materials, as well as acceptable limits for calibration verification; and (b)(2)(ii) Including at least a minimal (or zero) value, a mid-point value, and a maximum value near the upper limit of the range to verify the laboratory's reportable range of test results for the test system; and (b)(3) At least once every 6 months and whenever any of the following Statement of Deficiencies (X1) Provider/Supplier/CLIA Identification Number (X3) Date Survey Completed Name of Provider or Supplier Street Address, City, State -- 1 of 3 -- occur: (b)(3)(i) A complete change of reagents for a procedure is introduced, unless the laboratory can demonstrate that changing reagent lot numbers does not affect the range used to report patient test results, and control values are not adversely affected by reagent lot number changes. (b)(3)(ii) There is major preventive maintenance or replacement of critical parts that may influence test performance. (b)(3)(iii) Control materials reflect an unusual trend or shift, or are outside of the laboratory's acceptable limits, and other means of assessing and correcting unacceptable control values fail to identify and correct the problem. (b)(3)(iv) The laboratory's established schedule for verifying the reportable range for patient test results requires more frequent calibration verification. This STANDARD is not met as evidenced by: Based on the lack of records and interview of the laboratory director and technical consultant on 5/28/19, the laboratory failed to perform and document calibration procedures on their troponin test at least every 6 months. Findings included: The laboratory performed and reported approximately 50 troponin test results on patients each year. Laboratory records showed calibration verification was done on 5/23/19 and 10/22/18. There was no documentation of calibration performed before 10/22/18. D5783
