 Abstract
Annual proficiency surveys were conducted in March, May, and August of 2017 as the Korean Association of External Quality Assessment Service. Overall, four image samples (MPI-17-01, MPI-17-02, MPI-17-03, MPI-17-04) in the first trial, three image samples (MPI-17-05, MPI-17-06 , MPI-17-07) in the second trial, and a slide specimen (MPS-17-01) using parasite samples in the third trial were distributed to participating institutions. The first and second trial specimens were prepared by photographing slides made of formalinether concentrate of positive samples stored for educational purposes. The slide distributed in the third trial was prepared using cellophane tape, which was stored after diagnosis of the patients infected with Enterobius vermicularis . There were 191 participating institutions in the first, 204 in the second, and 212 in the third trial. The correct identification rates were 27.2% for MPI-17-01 Diphyllobothrium species (sp.), 96.6% for MPI-17-02 no parasite, 67.5% for MPI-17-03 Metagonimus yokogawai , 71.2% for MPI-17-04 Balantidium coli , 99.0% for MPI-17-05 Taenia sp., 99.0% for MPI-17-06 Trichuris trichiura , 92.7% for MPI-17-07 Cryptosporidium sp., and 96.7% for MPS-17-01 E. vermicularis . The current external quality assessment for clinical parasitology was performed using image samples and standard slides. Surveys of parasitic infections should be accompanied by continuous education on various parasitic infections, for which there was lack of experience of inspection in clinical laboratories. In the future, it will be necessary to establish a standard material using parasitic samples, and ultimately to conduct a survey on whole series of tests for the diagnosis of parasitic diseases.
