Medical COVID-19 Antigen Test Kit MSLDNA12

The Medical COVID-19 Antigen Saliva Test Kit MSLDNA12 is used for the qualitative detection of novel coronavirus (COVID-19) antigen in saliva sample, only for in vitro diagnostic use.

The COVID-19 Antigen Test Kit is used for the qualitative detection of novel coronavirus (COVID-19) antigen in saliva sample, only for in vitro diagnostic use.

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. Antigen is generally detectable in upper respiratory specimens during the acute phase of infection.

Rapid diagnosis of SARS-CoV-2 infection will help healthcare professionals to treat patients and control the disease more efficiently and effectively.

Medical COVID-19 Antigen Saliva Test Kit MSLDNA12 is based on the principle of highly specific antibody-antigen reaction and colloidal gold labeling immunochromatographic analysis technology. The reagent contains COVID-19 monoclonal antibody prefixed in the test area (T) on the membrane and the COVID-19 monoclonal antibody coated on the label pad-colloidal gold mixture.

The sample is dripped into the sample well and reacts with the COVID-19 monoclonal antibody which is bound to the pre-coated colloidal gold particles when testing. Then the mixture is chromatographed upwards with capillary effects. If it is positive, the antibody labeled by colloidal gold particles will first bind to the COVID-19 virus in the sample during chromatography. Then the conjugates are bound by the COVID-19 monoclonal antibody fixed on the membrane, and a red line appears in the test area (T). If it is negative, there's no red line in the test area (T). Whether the sample contains COVID-19 antigen or not, a red line will appear in the quality control area (C).

The red line appearing in the quality control area (C) is the standard for judging whether there are enough samples and whether the chromatographic process is normal, and it also serves as the internal control standard for the reagent.
