Abstract
(EN) Reagents, kits, and microfluidics devices are disclosed for detecting the presence and/or concentration of antibodies directed to microorganisms in human biological samples. Also disclosed are methods of production and use of the reagents, kits, and microfluidics devices. Anti-human immunoglobulin antibodies are utilized to enhance the signal produced by the assay.
(FR) L'invention divulgue des réactifs, des kits et des dispositifs microfluidiques pour détecter la présence et/ou la concentration d'anticorps dirigés contre des micro-organismes dans des échantillons biologiques humains. L'invention divulgue également des procédés de production et d'utilisation des réactifs, des kits et des dispositifs microfluidiques. Des anticorps anti-immunoglobuline humaine sont utilisés pour améliorer le signal produit par le dosage.
