The current status of HIV screening laboratories in Korea assessed by a questionnaire survey of participants in the KCDC HIV EQAS (2006)

Using a questionnaire, we assessed the current status of the quality management systems at HIV screening laboratories in Korea. The Korea Centres for Disease Control and Prevention HIV external quality assurance scheme (EQAS) questionnaire includes 18 items divided into five groups related to HIV testing: personnel, HIV test processes, participation in the Quality Assurance programme and HIV testing equipment. Five hundred and sixty-one HIV screening laboratories participated in this questionnaire investigation; data were collected from 233 public health centres, 309 hospitals or clinics, eight blood centres and 11 commercial laboratories. The total number of HIV screening tests was about 5.5 million in 2005. The average number of HIV tests per institution was highest in blood centres (308 561), followed by commercial laboratories (56 084), hospital or clinic laboratories (6756), and public health centres (1751). Equipment and HIV test methods varied between HIV screening laboratories, and, to manage the quality of their HIV testing, most laboratories participated in several evaluation programmes such as EQAS or a laboratory accreditation programme. This study is the first questionnaire survey of HIV testing laboratories in Korea. The results could be used to evaluate and promote the quality management of HIV testing laboratories.
