FluB Real Time PCR Kits Assay FIA Rapid Quantitative Test Kit In Nasopharyngeal And Oropharyngeal

【Intended use】

It is used for qualitative detection of influenza B virus antigens in human nasopharyngeal swab and oropharyngeal swab samples. It is applicable to the auxiliary diagnosis of influenza B virus infection.

【Inspection principle】

Double antibody sandwich method was used to detect influenza B virus antigens by immunochromatography. During detection, the treated extract is added to the sample adding hole of the test card. When the sample to be tested contains influenza B virus antigen and the antigen concentration is higher than the minimum detection limit, influenza B virus antigen first forms a reaction complex with the labeled antibody, and the reaction complex moves forward along the nitric acid fiber membrane under the action of chromatography, It is captured by the monoclonal antibody of influenza B virus nucleoprotein pre coated in the detection areas on the nitric acid fiber membrane, and a red reaction line is finally formed in the detection areas. At this time, the result is positive; On the contrary, when the sample does not contain influenza B virus antigen or the antigen concentration is lower than the minimum detection limit, there is no red reaction line in the detection area, and the result is negative. No matter whether the sample contains influenza B virus antigen, a red reaction line will be formed in the quality control area (c). The red reaction line displayed in the quality control area (c) is not only the standard to judge whether the chromatographic process is normal, but also the internal control standard of the reagent.

【Storage conditions and validity】

The kit should be stored at 4℃~30℃, out of direct sunlight. It is valid for 18 months. The test card should be used within 15 minutes after unsealing under the environment of 15℃~30℃ and 20% ~ 90% relative humidity.

The production date, batch number and expiration date are shown in the outer package of the product.
