title: [Evaluation of two immunochromatography kits for rapid diagnosis of rotavirus infections].
abstract: A prospective study was conducted to evaluate two immunochromatography (ICG) commercial kits for diagnosis of rotavirus infection, VIKIA Rota-Adeno (bioMérieux) and Simple Rota-Adeno (Operon). Reverse transcriptase and polymerase chain reaction (RT-PCR) with specific primers for the VP7 gene of group A rotavirus was used as the reference method. The sensitivity and specificity of the ICG tests compared with those of the reference method were 98.4% and 84.8%, respectively, for Simple Rota-Adeno (Operon), and 100% and 24.2% for VlKIA Rota-Adeno (bioMérieux). It is remarkable the low specificity of the latter method, which yields a high number of false positive results. The predictive value of a positive result by this method was only 71.6%. Most of the detected rotavirus strains corresponded to genotype G9P[8] (65%), followed by G1P[8] (25.4%) and G2P[8] (3.2%).
