利什曼病是由利什曼原蟲引起的人畜共患病,可引起人類皮膚及內臟黑熱病。臨床特征主要表現為長期不規則的發熱、脾臟腫大、貧血、消瘦、白細胞計數減少和血清球蛋白的增加,如不予合適的治療,患者大都在得病后1~2年內因并發其他疾病而死亡。本病多發于地中海國家及熱帶和亞熱帶地區,以皮膚利什曼病這種形式為常見。
【檢測原理】
本試劑盒采用膠體金免疫層析技術,檢測人血清中的利什曼原蟲特異IgG抗體。本試劑盒是用利什么曼原蟲純化抗原IgG抗體分別固相于硝酸纖維金標記得的鏈球菌G蛋白及其它的試劑制成。當今次那個是,金標記的鏈球菌G蛋白會與待血清的抗體結合形成復合物,若樣本中存在利什曼原蟲特異性抗體,該抗體與金標的鏈球菌G蛋白形成的復合物由于層析作用移動到檢測線區域時,則該復合物被固有相與檢測線區域內的利什曼原蟲捕獲而凝聚顯色。若血樣中沒有利什么曼原蟲特異抗體,則檢測線不顯色無論樣本中是否存在利什曼原蟲特異性抗體,一條色條帶都會出現質控區,作為層析過程很正常,試劑是否失效的內控標準。
除此之外本司還有登革熱、瘧疾、寨卡、西尼羅河、黃熱病、基孔肯雅熱、萊姆、中東呼吸綜合征、鉤端螺旋體、幽門螺旋桿菌、大腸桿菌、麻疹/風疹、腮腺炎、布魯桿菌、炭疽桿菌、巨細胞、EB病毒、狂犬病毒、腸道病毒71型等膠體金法、ELISA抗原抗體檢測試劑盒。
[detection principle]
This kit USES colloidal gold immunochromatography to detect the leishmania protozoa-specific IgG antibody in human serum.This kit is made by using protozoa purified antigen IgG antibody to solid phase streptococcus G protein labeled by nitrate fiber gold and other reagents.Times today that is, gold tag streptococcus will G protein and serum antibody to form complexes, if the sample of specific antibodies, leishmania, the antibody with the gold mark streptococcus G protein to form compounds by chromatographic area move to the line, the lines of the compound is inherent facies zones of leishmania capture and color.If there is no leishmania specific antibody in the blood sample, the detection line will not color whether there is leishmania specific antibody in the sample or not, a color band will appear in the quality control area, which is the internal control standard for the normal chromatography process and whether the reagent fails.
