Detection membrane strip, detection card and detection kit for allergen detection

Abstract

The invention provides a detection membrane strip, a detection card and a detection kit for allergen detection, which can be used for rapidly detecting whether a human body has lesion or immune tolerance reaction due to food, pollen, dust mites, mould and the like, the detection method is simple, convenient and rapid, and the detection result is accurate and reliable. Various allergic diseases caused by allergens to human bodies are avoided, different detection requirements are met, the cost is low, the structure is simple, assembly is easy, and the detection membrane strip, the detection card and the detection kit are suitable for large-scale production, can be suitable for whole blood detection, and are particularly suitable for self-inspection of infants and family members; the invention provides an immunofiltration device capable of limiting flow, and aims to enable liquid to only permeate through a target position, slow down the flow speed and improve the detection sensitivity. A formula of the sample diluent is provided, so that the treatment of a whole blood sample is facilitated, and the test is smoothly carried out; the invention provides the whole blood filter membrane, which is beneficial to filtering large-particle substances in a sample when detecting that the sample is whole blood, and is convenient for the sample to smoothly pass through the nitrocellulose membrane.

Description

technical field [0001] The invention relates to a detection device for allergen detection. [0002] Specifically, it relates to a detection film strip, a detection card and a detection kit for allergen detection. Background technique [0003] In recent years, the number of allergic patients is increasing, and the incidence of allergies is also increasing year by year. It is reported that 22% of the world's total population has allergic symptoms to varying degrees. Among the allergic reactions, more than 90% are caused by eight types of food, namely eggs, peanuts, milk, soybeans, wheat, tree nuts (nuts), shellfish (including crustaceans and molluscs), fish etc. Food allergy refers to a specific immune response that occurs in the body when the human body ingests a specific food. Food allergy is divided into IgE-mediated hypersensitivity and cell-mediated hypersensitivity (non-IgE-mediated hypersensitivity), and most food allergies are mediated by IgE. IgE-mediated allergic...

Problems solved by technology

However, the above-mentioned detection methods all have defects: radioallergen adsorption detection has nuclide pollution, and it needs to be equipped with instruments and professional personnel to operate; there are many methods for detecting binding enzymes in enzyme immunoassay, and the commonly used ELISA method takes a long time to operate, and Only one allergen can be detected per well, with high efficiency and low cost; immunoblotting has high sensitivity and can realize multi-throughput detection, but its operation is cumbersome and takes a long time; chemiluminescence has high sensitivity and can realize automatic operation, but it needs supporting equipment, and bedside detection cannot be realized, that is, random detection and detection
