Problems solved by technology

Bacterial culture method is the gold standard for detecting typhoid bacteria, but the cycle of bacterial culture is long, and the detection time needs to be more than 5 days, and it is easily affected by factors such as antibiotics, resulting in missed detection; Positive results only appear in the second week of the disease course, and the specificity is poor, the sensitivity is not high, and the positive rate is also low
The above two methods have the defects of long detection time and low efficiency.

Embodiment

[0026] like Figure 1-3 As shown in the figure, a typhoid antigen-antibody dual card detection kit includes a housing and a dual detection card located inside the housing. The dual detection card is composed of an antibody detection card 100 and an antigen detection card 200 arranged side by side. The antibody detection card 100 and the antigen detection card 200 are respectively composed of a bottom plate 300 and a test strip 400 pasted above the bottom plate 300. The test strip 400 is composed of a sample pad 410, a gold standard pad 420, a NC The membrane 430 (that is, the nitrocellulose membrane) and the sample suction pad 440 are erected and formed, and the casing is provided with a sample application hole and an observation hole corresponding to the positions of the sample pad 410 and the NC membrane 430;

[0027] The gold label pad 420 of the antibody detection card 100 contains typhoid H antigen-colloidal gold complex and rabbit IgG antibody-colloidal gold complex, and...

Abstract

The invention discloses a typhoid antigen-antibody bigeminy card detection kit which comprises a shell and a bigeminy detection card located in the shell, and the bigeminy detection card is composed of an antibody detection card and an antigen detection card which are arranged side by side; an antibody detection line of the antibody detection card is coated with a typhoid H antigen, and an antigen detection line of the antigen detection card is coated with a typhoid monoclonal antibody. The kit disclosed by the invention realizes joint detection of the typhoid bacteria antibody and antigen, shortens a disease detection window period, is beneficial to diagnosis and treatment of diseases, and has the advantages of simplicity in operation, high sensitivity and specificity and short detection time.

Description

technical field [0001] The invention relates to the technical field of immunological detection devices, in particular to a typhoid antigen-antibody dual card detection kit. Background technique [0002] At present, the main methods for detecting typhoid fever are bacterial culture method and Wida test method. Bacterial culture method is the gold standard for the detection of typhoid bacteria, but the period of bacterial culture is long, the detection time is more than 5 days, and it is easily affected by factors such as antibiotics, resulting in missed detection; The positivity appeared only in the second week of the course of the disease, with poor specificity, low sensitivity, and low positive rate. The above two methods have the defects of long detection time and low efficiency. SUMMARY OF THE INVENTION [0003] To solve the above problems, the present invention provides a typhoid antigen-antibody dual card detection kit. [0004] The present invention adopts followi...
