Streptococcus-A quantum dot immunochromatographic detection reagent card and preparation method thereof

Abstract

The invention discloses a streptococcus-A quantum dot immunochromatographic detection reagent card and a preparation method of the streptococcus-A quantum dot immunochromatographic detection reagent card, and aims to provide the streptococcus-A quantum dot immunochromatographic detection reagent card which is simple, high in sensitivity and reliable in detection results. The detection reagent card comprises a box body (6), wherein a piece of detection test paper is arranged in the box body (6); the detection test paper comprises a bottom plate (1); a sample pad (2), an anti-streptococcus-A quantum dot anti-body markup pad (3), a coating film (4) and a water absorption pad (5) are connected with the bottom plate (1) in sequence; a streptococcus-A quantum antibody detection area line T and a goat anti-rabbit polyclonal anti-body quality control area line C are arranged on the coating film (4); the two lines are arranged in parallel; the streptococcus-A quantum dot immunochromatographic detection reagent card and the preparation method thereof belong to the field of fluorescence immunoassay.

Description

technical field [0001] The invention discloses a detection reagent card, specifically, a detection reagent card for determining group A streptococcus in throat swabs. The invention also discloses a preparation method of the detection reagent card, which belongs to the field of fluorescence immunoassay . Background technique [0002] One of the common pathogens of upper respiratory tract infection in children, the positive rate of group A streptococcus in children with respiratory tract infection is about 23.2%. If anti-infective treatment is not received in time, including acute pharyngitis, pyocytosis, toxic shock syndrome, invasive fasciitis, scarlet fever, pneumonia, erysipelas and allergic diseases caused by group A streptococcal infection, such as acute rheumatic fever , Rheumatic heart disease, acute glomerulonephritis. At present, the common identification methods of group A streptococcus mainly include clinical experience screening and bacterial culture method. ...

AI Technical Summary

Problems solved by technology

Bacterial culture method is the "gold standard" for the diagnosis of group A streptococci. 2 Or under anaerobic conditions, the isolation rate of group A streptococci can be increased, and finally serological methods are used to identify group A streptococci from other β-hemolytic streptococci, especially group C and group G, but it takes a long time
