ISO 20046:2019 is an international standard that provides performance criteria for cytogenetic laboratories using Fluorescence In Situ Hybridization (FISH) translocation assays to assess exposure to ionizing radiation. It outlines requirements for quality assurance, quality control, and performance evaluation of these biological dosimetry methods. This standard is focused on laboratories that use FISH to assess radiation exposure and provides guidance on customer and laboratory responsibilities, confidentiality, safety, sample processing, and scoring procedures for translocations.
