COVID-19/Influenza A&B Antigen Rapid Test Kit (Colloidal Gold)

Short Description:

Product Detail

Intend Use:

◆Applied for detection during epidemic frequency period, to differentiate FluA/B and COVID-19 infection， help develop a diagnosis and treatment plan.

◆COVID-19/Influenza A&B Antigen Rapid Test Kit (Colloidal Gold)is an immunochromatographic assay for rapid, it is designed for the rapid qualitative detection of severe acute respiratory syndrome coronavirus (SARS-CoV-2) Antigen and Influenza A&B virus nucleoprotein antigen from the nasal swab specimen or throat swab specimen. The test provides preliminary test results. The test is to be used as an aid in the diagnosis of SARS-CoV-2 and Influenza A&B virus infection. This test card cannot be used as the basis to diagnose or exclude SARS-CoV-2 and Influenza A&B virus infection

Sampling method

◆Oropharyngeal swab, Nasopharyngeal swab

Working Principle:

◆COVID-19/Influenza A&B Antigen Rapid Test Kit (Colloidal Gold) is based on the principle of capture immunoassay for determination of COVID-19 antigen and Influenza A&B virus nucleoprotein antigen from the nasal swab specimen or throat swab specimen. When the specimen is added into the test device, the specimen is absorbed into the device by capillary action. If the sample contains novel coronavirus antigen, the antigen combined with the colloidal gold labeled novel coronavirus antibody, and when the novel coronavirus antigen level in the specimen is at or above the minimum detection level, and the immune complex further binds to the coated antigen in the T line and this produces a colored test band that indicates a positive result. When the novel coronavirus Antigen level in the specimen is zero or below the minimum detection level, there is not a visible colored band in the Test Region of the device. This indicates a negative result. When the sample contains influenza A & B virus antigens, the content of influenza A & B virus antigens in the sample is at or above the minimum detection level, influenza A & B virus antigens originally form antigen-antibody complexes with labeled antibodies, the complex flows in the upper layer of the reagent membrane, combine the influenza A nucleoprotein monoclonal antibody and (or) influenza B nucleoprotein monoclonal antibody coated by the detection area A and (or) B area on the membrane respectively, in the Test Region A and (or) B, a purplish red band finally appears, and the result is positive, if there is no purplish red stripe, the result is negative.

◆ The magenta stripe in the quality control area is to determine whether there are enough samples, whether the tomographic process is standard or not, it also serves as an internal control standard for reagent. If the quality control line C does not appear, it indicates that the test result is invalid, and the sample needs to be tested again.

Product detail:

◆ The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection, asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.

◆Influenza virus, abbreviation is influenza, it is the acute respiratory tract infection that causes by influenza virus, have very strong infectivity, pread mainly through coughing and sneezing, influenza viruses often cause fever, fatigue, muscle soreness and mild to moderate respiratory symptoms, which can be more severe in the elderly or young children with weakened immune systems and in some patients with impaired immunity, Such as pneumonia, myocarditis, or heart and lung failure. Generally, outbreaks occur in spring and winter, divided into influenza A virus, influenza B virus and influenza C virus. Influenza A virus, which can infect humans, birds and mammals, is highly variable and is capable of causing a world influenza pandemic, Influenza B viruses often cause localized outbreaks, Influenza C viruses are very stable antigenicity and generally do not cause epidemics.

◆To reduce the chance of bleeding, to facilitate some areas of the blood cannot be measured.

◆To be able to obtain the result rapidly within 15 min.

◆The procedure is simple and easy to practice.

◆It is applicable to samples from different sources including nasopharyngeal swab and pharyngeal swab.
