Summary:
Summary Statement of Deficiencies D5311 SPECIMEN SUBMISSION, HANDLING, AND REFERRAL CFR(s): 493.1242(a) The laboratory must establish and follow written policies and procedures for each of the following, if applicable: (1) Patient preparation. (2) Specimen collection. (3) Specimen labeling, including patient name or unique patient identifier and, when appropriate, specimen source. (4) Specimen storage and preservation. (5) Conditions for specimen transportation. (6) Specimen processing. (7) Specimen acceptability and rejection. (8) Specimen referral. This STANDARD is not met as evidenced by: Based on review of the validation summary, review of the procedure and interview with the testing person (TP) and technical supervisor (TS), the laboratory failed to establish written policies and procedures for specimen storage and preservation for testing on the liquid chromatography with tandem mass spectrometry (LC/MS/MS) instrument. Findings: 1. The "Stability Study" section on page 4 of the laboratory's "Analytical Method Validation Report (November 2019) LC/MS/MS Pain Panel" states that specimens are stable when stored for 5 days, but doesn't specify under what conditions the specimens were stored at. 2. The "Testing Information" chart listed on page 7 of the laboratory's confirmatory testing procedure stated that specimens are stable less than 5 days at ambient temperature, at least 14 days at refrigerated temperatures (2 to 8C), and greater than 14 days at frozen temperatures (-20 to -5C). The laboratory's stability studies did not establish a specimen's stability beyond 5 days and the procedure does not include a reference to another study that established specimen stability. 3. The "Acceptance Criteria" section on page 33 of the laboratory's confirmatory testing procedure states that specimens should be rejected if "collected more than 30 days prior and / or not refrigerated." This statement conflicts with the previous statement that specimens are stable less than 5 days at ambient temperature. 4. During the survey on 02/16/2021 at 10:00 AM, the TP stated that the laboratory stores each specimen in the refrigerator for 6 weeks in case they receive a request to Statement of Deficiencies (X1) Provider/Supplier/CLIA Identification Number (X3) Date Survey Completed Name of Provider or Supplier Street Address, City, State -- 1 of 5 -- re-test a specimen. The laboratory's confirmatory testing procedure does not include instructions for the length of storage time and temperature once the specimens are tested. 5. During the survey on 02/16/2021 at 10:03 AM, the TS confirmed that specimens should be stored frozen for up to 6 weeks after specimen receipt and that the laboratory only performed stability studies showing that specimens were stable up to 5 days. D5403 PROCEDURE MANUAL CFR(s): 493.1251(b) The procedure manual must include the following when applicable to the test procedure: (1) Requirements for patient preparation; specimen collection, labeling, storage, preservation, transportation, processing, and referral; and criteria for specimen acceptability and rejection as described in 493.1242. (2) Microscopic examination, including the detection of inadequately prepared slides. (3) Step-by-step performance of the procedure, including test calculations and interpretation of results. (4) Preparation of slides, solutions, calibrators, controls, reagents, stains, and other materials used in testing. (5) Calibration and calibration verification procedures. (6) The reportable range for test results for the test system as established or verified in 493.1253. (7) Control procedures. (8)
