A simple method of rubella antigen production by treatment with sodium desoxycholate for use in enzyme immunoassay (IMT-ELISA) is presented. When this assay was compared with a commercial test (Enzygnost-Rubella, Behring), in the study of 108 sera and 118 filter paper blood samples, 96.9% (219/226)...

Description
Summary:A simple method of rubella antigen production by treatment with sodium desoxycholate for use in enzyme immunoassay (IMT-ELISA) is presented. When this assay was compared with a commercial test (Enzygnost-Rubella, Behring), in the study of 108 sera and 118 filter paper blood samples, 96.9% (219/226) overall agreement and correlation coefficient of 0.90 between absorbances were observed. Seven samples showed discordant results, negative by the commercial kit and positive by our test. Four of those 7 samples were available, being 3 positive by HI.Um método simples de produção de antígeno de vírus da rubéola, por extração com desoxicolato de sódio para aplicação no ensaio imunoenzimático, IMT-ELISA, é apresentado. Este ensaio comparado com ELISA comercial (Enzygnost-Rubella, Behring), no estudo de 108 soros e 118 amostras de papel de filtro apresentou 96,9% (219/226) de concordância e um coeficiente de correlação de 0,90 entre as absorbâncias. Sete amostras apresentaram resultados discordantes, negativos pelo ensaio comercial e positivos pelo IMT-ELISA. Destas, 4 foram testadas por RIH, observando-se positividade em 3.
