The present invention relates to a method for diagnosing an allergy, comprising the steps of bringing into contact of basophils from a whole blood sample of a patient with an allergen in an aqueous solution in the presence of whole blood, with a volume content of whole blood in the aqueous solution of at least 20 percent by volume, under conditions that allow activation of the basophils by the allergen, enrichment of the basophils from step a) and detection of activated basophils, wherein the detection is carried out in that the expression of a marker characteristic of activated basophils is detected by means of chemiluminescence; and a kit comprising a vessel for bringing the basophils into contact with the allergen, wherein the vessel is preferably a microtiter plate, optionally an allergen, an agent for detecting a marker characteristic of activated basophils by means of chemiluminescence, wherein the agent is preferably a ligand against the marker provided with a label capable of chemiluminescence and the ligand more preferably is a monoclonal antibody, optionally an agent for stopping activation of the basophils, an optionally immobilizable ligand that binds to a polypeptide located on the cell surface of basophils independently of its activation state, wherein the ligand is preferably a monoclonal antibody against the polypeptide, and optionally an agent for lysing and/or removing erythrocytes.
本发明涉及一种诊断过敏症的方法,包括以下步骤:在有全血存在的情况下,使患者全血样本中的嗜碱性粒细胞与
水溶液中的过敏原接触,
水溶液中的全血体积含量至少为 20%、在可使嗜碱性粒细胞被过敏原活化的条件下,富集步骤 a)中的嗜碱性粒细胞并检测活化的嗜碱性粒细胞,其中检测是通过
化学发光方法检测活化的嗜碱性粒细胞特征标记物的表达;试剂盒,包括用于使嗜碱性粒细胞与过敏原接触的容器(容器最好是微孔板)、过敏原、通过
化学发光检测活化的嗜碱性粒细胞特征标记物的试剂(试剂最好是带有
化学发光标记的标记物
配体,
配体最好是单克隆
抗体)、可选的停止嗜碱性粒细胞活化的药剂,可选的与位于嗜碱性粒细胞细胞表面的
多肽结合的可固定
配体,与嗜碱性粒细胞的活化状态无关,其中
配体最好是针对该
多肽的单克隆
抗体,以及可选的裂解和/或清除红细胞的药剂。
