Abstract

In both 2016 and 2017, the cytogenetic and molecular cytogenetic programs conducted three assessments for the Korean Association of External Quality Assessment Service. A total of six cases with chromosomal aberrations were distributed in 2016, and nine cases were examined in 2017 in the chromosome surveys. For the fluorescence in situ hybridization surveys, six cases and nine cases were assessed in 2016 and 2017, respectively. A total of 38 laboratories in 2016 and 39 laboratories in 2017 participated in the cytogenetics program. In the molecular cytogenetics program, a total of 32 laboratories participated in 2016, and 31 laboratories participated in 2017. Most of the participating laboratories showed acceptable results for the cytogenetics and molecular cytogenetics programs. For the unacceptable results, there were various annotation errors, suggesting the need for continuous education and quality control.
