D5473 CONTROL PROCEDURES CFR(s): 493.1256(e)(2)(g) (e)(2) Each day of use (unless otherwise specified in this subpart), test staining materials for intended reactivity to ensure predictable staining characteristics. Control materials for both positive and negative reactivity must be included, as appropriate. This STANDARD is not met as evidenced by: Based on review of the laboratory's procedure, control slide logs, test volume, and in an interview with the consultant, the laboratory failed to define intended reactivity to -- 2 of 3 -- ensure predictable Hematoxylin & Eosin (H&E) staining characteristics when documenting the quality for one of one stain. Findings included: 1. Review of the laboratory's procedure and "CONTROL SLIDE LOG" (first patient slide of the day documented for quality, total of 28) from 2/14/24 to 7/8/26 did not include defined H&E intended reactivity to ensure predictable staining characteristics. 2. Review of the laboratory's annual test volume was 300 (Histopathology - Mohs). 3. During an interview on 7/28/26 at 11:00 am, the consultant confirmed the laboratory had not defined intended reactivity to ensure predictable H&E staining characteristics. -- 3 of 3 --

Summary Statement of Deficiencies D5411 TEST SYSTEMS, EQUIPMENT, INSTRUMENTS, REAGENT CFR(s): 493.1252(a) Test systems must be selected by the laboratory. The testing must be performed following the manufacturer's instructions and in a manner that provides test results within the laboratory's stated performance specifications for each test system as determined under 493.1253. This STANDARD is not met as evidenced by: Based on review laboratory logs, interview with the testing person (TP), and the medical assistant (MA) at 1:00 PM, The lab did not perform maintenance procedures on all lab equipment to ensure accurate and reliable patient testing. Findings: 1. The lab performs MOHS surgery. The lab prepares slides with patient tissue collected during the surgery procedures for review by the pathologist. 2. The autoclave is used to sterilizes tools used during surgery procedures. 3. The lab did not perform spore checks on the autoclave to ensure contamination was not present. 4. The MA stated that she was unaware that spore checks needed to be performed on the autoclave. 5. The TP confirmed that spore checks were not performed on the autoclave to ensure contamination was not present.

The findings included: 1. Review of the Leica's (manufacturer of the cryostat) instructions for storage and operation of the cryostat revealed that the cryostat must be operated consistently, between 18-35 degrees centigrade (C). The storage of the cryostat must be between 5-50C. It should be noted that the cryostat is operated and stored in different rooms. Review of the laboratory's procedure manual did not reveal instructions to monitor the room temperature where the cryostat is stored or operated. 2. Review of the Leica's (manufacturer cryostat) instructions for storage and operation revealed that the maximum non-condensing relative humidity to be 60%. Review of the laboratory's procedure manual did not reveal instructions to monitor the relative humidity where the cryostat is stored or operated. 3. Review of the Leica's (manufacturer of the microscope) instructions revealed that the operating temperature to be between 10-40C and the storage temperature to be between -20-52 C. It should be further noted that the microscope is operated and stored in different 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 -- rooms. Review of the laboratory's procedure manual did not reveal instructions to monitor the room temperature where the microscope is stored or operated. 4.
