Abstract
(EN)
This disclosure provides a method for analyzing peripheral blood leukocytes. In some embodiments, method may comprise: (a) labeling peripheral blood leukocytes isolated from a patient that has or is suspected of having inflammatory bowel disease (IBD) with a panel of distinguishably-labeled antibodies and (b) analyzing binding of the antibodies to the peripheral blood leukocytes. Kits for performing the method are also provided. Results from the analysis can be used to make a diagnosis of Crohn's disease or ulcerative colitis.

La présente invention concerne un procédé d'analyse de leucocytes du sang périphérique. Dans certains modes de réalisation, le procédé peut comprendre : (a) le marquage des leucocytes du sang périphérique isolés provenant d'un patient atteint ou suspecté d'être atteint d'une maladie intestinale inflammatoire avec une batterie d'anticorps marqués de manière distincte et (b) l'analyse de la liaison des anticorps aux leucocytes du sang périphérique. L'invention concerne également des trousses pour mettre en œuvre ledit procédé. Les résultats de l'analyse peuvent être utilisés pour effectuer un diagnostic de la maladie de Crohn ou de la colite ulcéreuse.
