title: [Evaluation of the efficiency of external assessment of the quality of determining antibodies to hepatitis C virus in the network of screening laboratories].
abstract: A regional external quality assessment (EQA) system for determining anti-hepatitis C virus (HCV) was developed and introduced. For this, a control panel comprising 14 samples with anti-HCV and 6 samples without anti-HCV was tested in the reference laboratory of Moscow Infectious Hospital One. A total of 6 sessions were conducted with the participation of 8 laboratories. The regional EQA system covering a limited number of laboratories was shown to significantly improve the quality of detection of hepatitis C virus antibodies. The optimal multiplicity of sessions for the developed EQA system was ascertained to be once fortnight. It is possible to define the current rating of screening laboratories in the sensitivity criterion and to elaborate address organizational-and-methodic measures according to the results of control tests.
