พื้นที่COVID-19 Antigen RapidTest (Lateral Chromatography) is an In Vitro Immunochromatographic Method for the Qualitative Detection of SARS-CoV-2 Nucleocapsid Protein Antigens from Aggregated Nasopharyngeal or Nasal Swabs of Suspected COVID-19 Patients . The rapid antigen detection reagent uses the double-antibody sandwich method to legally detect the new coronavirus antigen in nasopharyngeal and oropharyngeal swabs. It is designed to help rapid diagnosis of SARS-COV-2 infection.

Test principle of rapid antigen detection reagent

During the detection process, the gold-labeled anti-coronavirus monoclonal antibody on the marker plate combines with the new coronavirus antigen in the sample to form a complex, and the reaction complex moves forward along the nitrocellulose membrane under the action of chromatography, and passes through the nitrocellulose . Pre-coat the anti-2019-ncov monoclonal antibody on the detection area (T) on the flat membrane, and finally form a red reaction line in the T area. If the sample does not contain the novel coronavirus pneumonia virus antigen, the T zone cannot form a red reaction line. No matter whether the test sample contains the novel coronavirus antigen or not, the quality control area (C) will always form a red reaction line.

Since the possibility that the subject was only infected with SARS-CoV-2 cannot be ruled out, negative results should be considered as hypothetical results. It should not be used as the sole basis for treatment, patient management, and infection control. Negative results should be considered based on the patient's recent exposure history, past medical history, and clinical signs and symptoms consistent with COVID-19. Patients should be managed with molecular testing if necessary.
Scope of application: It is suitable for suspected patients with symptoms, mild symptoms, or even asymptomatic, and it is also suitable for the detection of close contacts of patients and isolated personnel.

How to use the quick test package

Collect oropharyngeal, nasopharyngeal samples

Do a good job of cleaning your handsRemove one extraction tube and one COVID-19 antigen test kit (lateral chromatography) from the foil pouch immediately before testingThere are labels on the test kit and extraction tube for each specimen to be tested. Place the labeled withdrawal tube in the designated area of the workspaceCollecting nasopharyngeal or oropharyngeal samples: When taking a nasal swab sample, carefully insert the swab included in the kit into the nostril where the most secretions can be observed with the naked eye.Gently rotate and push the swab to the resistance point of the turbinates (approximately 2.0-2.5 cm close to the nostril), then roll the swab on the nasal wall about 5 times, and finally remove the swab

Prepare test samples

Immediately after specimen collection, soak the swab in sample extraction bufferThe sample is completely extracted, penetrated into the buffer swab, rotate the mop against the tube wall repeatedly for 10 seconds, then hold the tube with your finger (the tube wall is semi-solid) squeeze and scrub several times and slowly remove the swab tubeThe purpose of the swab squeezing the tube wall is important because it keeps as much of the fluid-containing specimen as possible in the tube. After removing the swab and discarding it in the biohazardous waste container, place the nozzle (supplied in the kit) on top of the suction tube firmly over it and gently shake the suction tube to mix the liquid inside

test sample

1. Please read the instructions for use carefully before testing.
2. Turn the specimen tube upside down, keep it vertical, squeeze the test tube, and add more than 3 drops of sample solution into the test box through the test tube nozzle.
3. Start the timer. Visually read results in 15 minutes, invalid results after 30 minutes
