면역혈청검사 신빙도조사 결과보고(2004)

Abstract

The followings are the results for external quality assessment (EQAI in immunoserology for 2004: 1. Evaluation of EQA was done In 2 trials In May and November, about 99% of laboratories partlcipating average 8 4 items. EQA for anti-HBc test was newly started In 2004. 2. Commercial control, MAS Immunology Control from Medical Analysis Systerms (Camarillo, CA, USA) was used to assure the quailty of quantitative results of C-reactive protein (CRPI, rheumatoid factor (RF) and anti-streptolysin O (ASO) tests in 2004 All the specimens for lmmunoserology in EQA were delivered refrigerated for the flrst time, being received within 48 hours after sending. 3. EQA for detection of HBsAg mutants was tried for the flrst time, using the recombinant HBsAg mutant (Gly/Arg 145) kindly provided by Abbott Laboratories, USA. 4. The laboratorles using immunochromatography assay (ICA) were increased, however, many laboratories using ICA reported falsely negative for the positive specimens. The sensitivity of ICA test kits as well as various factors influencing the ICA results should be evaluated. 5. Standardization of methods including calibrators for quantitative results should be required for the harmonization of results.
