PG - e96 LID - 10.1002/cphg.96 [doi] AB - In order to comply with regulations set by established local, state, and federal agencies and other regulatory organizations, such as the College of American Pathologists and the International Organization for Standardization, a clinical laboratory needs to develop procedures for the processes of validating laboratory-developed tests (LDTs) and establishing performance specifications for these assays prior to use in clinical testing. This is applicable to all fluorescence in situ hybridization (FISH) assays. Even Food and Drug Administration-approved FISH assays must undergo some form of verification before implementation in the clinical laboratory. The process of validating an assay as an LDT must include a plan, a procedure, and a report. The validation studies described here include metaphase and interphase FISH methodology for identification of the LSI EGR1/D5S23, D5S721 dual-color probe, which labels distinct biomarkers consistent with myeloid hematologic disorders, including myelodysplasias and acute myeloid leukemia.
