If you are in a large hospital system, the Clinical Engineering department will do a safety, operational, and functional inspection. Design your Staining Protocol Validation Worksheet with the following details: You are required to keep the records of the Instrument Verification and the Staining Protocol Validations for the years you own the instrument plus two years. ?:0FBx$ !i@H[EE1PLV6QP>U(j The American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines have clearly defined intra-tumor heterogeneity of HER2 amplification (i.e., HER2/CEP17 signal ratios >2.2 in 5%-50% of the neoplastic cells).
