Abstract:
The followings are the results for external quality assessment (EQA) in immunoserology for 2005: 1.Evaluation of EQA was done in 2 trials in May and December, about 99% of laboratories participating average 8.4 items. The results were collected via internet for the first time and 66~78% of laboratories have sent their results via internet. 2.Commercial controls, MASR Immunology Control from Medical Analysis Systems (Camarillo, CA, USA) and Immunology Control (Immuno-Q-sera I, SEIKEN, Japan) were used to assure the quality of quantitative results of C-reactive protein (CRP), rheumatoid factor (RF) and anti-streptolysin O (ASO) tests. All the specimens for Immunoserology in EQA were delivered refrigerated, being received within 48 hours after sending. 3.Commercial control for serologic tests for syphilis, Syphilis Control (Mediace RPR con, Sekisui, Japan) was newly introduced in 2005. 4.The laboratories 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.
