Evaluation of two (02) platforms for chemiluminescence-based detection of anti-rubella IgG antibodies in a sub-Saharan country, C ôte d'Ivoire.

This study aimed to evaluate two chemiluminescence platforms, Architect i2000SR and Maglumi 800 for rubella biological diagnosis in Côte d'Ivoire. Blood samples were taken from 113 pregnant women aged 15 to 30 in prenatal care. Samples were analyzed for Rubella IgG detection at the NBTS laboratory on the evaluated platforms and the Cobas e601 used as a reference. The majority of women were in their second trimester of pregnancy. Among them, only 13.3% were vaccinated against rubella. The evaluated platforms showed good precision with coefficients of variation >10%. Regarding analytical performances, sensitivities were 97.53% and 96.29% whereas specificities were 100% and 96.88% for Architect I2000SR and Maglumi800, respectively. Both platforms showed good agreement with cobas e601 for antibody levels <200 IU/ml and <350UI/ml for Architect and Maglumi 800, respectively. Findings of the current study revealed that the two platforms have similar features with Cobas e601 and could be used routinely for the serological diagnosis of rubella. However, the results of one platform should not be extrapolated to another. PMID: 32602401 [PubMed - as supplied by publisher]
