Paragonimiasis detection device and method for making same

Abstract

The invention discloses a device for detecting paragonimiasis and preparation method, comprising a label pad, a detecting layer, wherein the labelled detection antigen is on the labelled pad and the detection antigen is the lung fluke ESP protein represented by the amino acid sequence SEQ ID NO.2. The preparation method comprises preparing the lung fluke ESP protein and polyclonal antibody thereof, and preparing the label pad, the detection layer, the sample pad, the absorption pad and the detection device. The detection device prepared by the preparation method has features: high specificity, sensitivity, small cross reaction with the clonorchiasis and schistosomiasis, false positive rate lower than ELISA method, with curative effect evaluating function. The detection result becomes negative in 3-6 monthes after curing the paragonimiasis by effective medicine and the negative rate is higher than the ELISA method and the device for detecting paragonimiasis can accurately, quickly, simply perform diagnosis, differential diagnosis and evaluation of the curative effect with important clinical application value.

Description

technical field [0001] The invention relates to a detection device, in particular to a paragonimiasis detection device and a preparation method thereof. Background technique [0002] Paragonimiasis (Paragonimiasis) is a common and important zoonotic parasitic disease, mainly prevalent in Asia, Africa and Latin America, especially in Asia, prevalent in 22 provinces, municipalities and autonomous regions in my country, It is estimated that about 2 million people are infected every year, seriously endangering human health, especially the health of adolescents and children. [0003] Paragonimiasis is mainly caused by mechanical damage caused by paragonimiasis (larvae or adults) migrating and living in human tissues and organs, and immunopathological reactions caused by their metabolites. In my country, the pathogenic parasites are mainly lung fluke wescheri and lung fluke steineri, and their adults parasitize in the muscles and organs of carnivorous animals such as humans, dogs,...
