Vitro diagnosis detecting test paper and method for making same

Abstract

The invention discloses an in-vitro diagnostic check test strip and a manufacturing method thereof. The in-vitro diagnostic check test strip comprises a substrate, a reaction membrane and a mat, wherein, the substrate is adhered with the reaction membrane and the mat, one end of the reaction membrane is mutually connected with the mat in a lapping joint way, the substrate is made of transparent plastic or PVC material, the surface of the substrate, which is adhered with the reaction membrane, is provided with parallel checking line and quality-control line, and the mat is coated with colloidal gold solution or colored latex solution with the diameter range of 10nm to 50nm; the manufacturing method comprises the steps of preparation of the reaction membrane, marking and solid phase of the mat, assembly and cutting. The invention has the advantages of being capable of judging the testing result directly by the transparent substrate, preventing the volatilization of liquid and the infiltration of takeout liquid, causing the testing result to be more accurate, reducing nonspecific adsorption during testing reaction, reducing reaction background, preventing tracer from being adsorbed on the reaction membrane, guaranteeing fast elution and release, and being simple and convenient and feasible.

Description

Technical field:

[0001] The invention relates to an in vitro diagnostic test strip and a preparation method thereof, belonging to the field of medical testing. Background technique:

[0002] In the existing reaction test strips used for pregnancy detection, the substrate is not transparent, and the detection line and quality control line on the reaction layer are directly in contact with the air, so that the test liquid is volatilized, and at the same time, the external liquid is easy to penetrate into the reaction layer , affect the test results, and during the reaction, the detection solution needs to be absorbed by the absorbent pad, which has a complex structure, troublesome production, and waste of cost. When preparing the test strip, it is not used for membrane sealing and soaking treatment, which increases the non-specificity of the test reaction. Heterotropic adsorption enhances the background of the reaction. Invention content:

[0003] The purpose of the present...
