Title
(DE) In vitro-Test für Leukozyten in einer Fäkalienprobe unter Verwendung eines gegen Lactoferrin gerichteten Antikörper
(EN) In vitro test for leukocytes in a fecal sample using an antibody to lactoferrin
(FR) Test in vitro pour les leukocytes dans un échantillon fécal mettant en oeuvre un anticorps spécifique pour la lactoferrine
Abstract
(EN)
An in vitro test for determining the presence of leukocytes in a body fluid or tissue sample which is sensitive to the numbers of leukocytes typically found in inflammatory processes, such as diarrheal specimens, by testing the fecal sample with an assay utilizing an antibody for lactoferrin. Additionally, the test can be used to detect low white blood cell counts as low as about 200 WBCs/ul.

(FR)
Test in vitro permettant de déterminer la présence de leucocytes dans un liquide biologique ou un échantillon de tissu, lequel est sensible au nombre de leucocytes habituellement rencontrés dans des processus inflammatoires, tels que des échantillons diarrhéiques consistant à tester l'échantillon de matière fécale au moyen d'un dosage utilisant un anticorps pour la lactoferrine. On peut également utiliser le test afin de détecter des globules blancs en nombre faible allant jusqu'à environ 200 WBCs/ul.
