Nasal Swab Covid-19 Antigen Detection Kit 93% High Sensitivity

COVID-19 Antigen Rapid Test Kit (1-Pack): Oropharyngeal/Nasopharyngeal Swab Test​

Description of covid antigen test kit:

The covid antigen detection kit is an immunochromatographic method for the rapid, qualitative detection of SARS-CoV-2 in nasopharyngeal (NP) and nasal (NS) swab samples, either directly or after swab collection. 2 Nucleocapsid protein antigens. Added to the virus transmission medium by individuals suspected of having covid by a healthcare provider, covid antigen detection kit testing is limited to moderate, high, or exempt complexity testing by accredited accredited laboratories. Authorized for point-of-care (POC) use, the test is used to identify SARS-CoV-2 nucleocapsid antigens typically detected in upper respiratory tract samples during the acute phase of infection. A positive result indicates the presence of viral antigens but requires clinical correlation with the patient's medical history and other diagnostic information to determine infection status, and a positive result does not exclude bacterial infection or co-infection with other viruses.

Precautions:

Negative results from covid test kits should be considered presumptive, do not exclude SARS-CoV-2 infection, and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions. Negative results should be considered in conjunction with the patient's recent exposure, medical history, and the presence of clinical signs and symptoms consistent with COVID-19, and confirmed by molecular analysis, if necessary, for patient management.

covid antigen test kit uses:

The covid antigen test kit is used for the direct and qualitative detection of SARS-CoV-2 antigen in nasopharyngeal and oropharyngeal secretion specimens. Provides clinical results in 15 to 30 minutes, and visual interpretation of results does not require special equipment.

Instructions for use of covid antigen test kit:

Covid antigen test kit nasal swab specimen collection:

When collecting a nasal swab sample, carefully insert the swab (provided in the kit) into the nostril with the most visual secretions. Gently rotate, pushing the swab until it meets resistance at the level of the turbinate (approximately 2.0-2.5 cm or nearly 1 inch into the nostril). Roll the swab around the nose wall about 5 times and remove it from the nostril.



Sample Preparation:
Unscrew the cap of the sample extraction buffer bottle, squeeze the sample extraction buffer bottle, and add the sample extraction buffer to the extraction tube. (See Figure 2) Immediately after specimen collection, immerse the swab in the sample extraction buffer. (See Figure 3) To allow the extracted sample to fully penetrate the buffer of the swab, rotate the swab against the tube wall repeatedly for 10 seconds, then hold the tube with your fingers (the tube wall is semi-solid) and squeeze and wipe Several times, slowly remove the swab from the tube at the same time. (See Figure 4) The purpose of squeezing the swab against the tube wall is important because it keeps the liquid-containing specimen as much as possible in the tube. After removing the swab and discarding it in the biohazard waste container, tie the nozzle (provided in the kit) to the top of the extraction tube and gently shake the tube to thoroughly mix the liquid inside, see Figure 5.



test program:
1. Please read the instructions carefully before testing.
2. Invert the specimen extraction tube and keep it upright. Squeeze the test tube, and add more than 3 drops of the sample solution (about 70-90 μL) into the test tube through the nozzle of the test tube.
3. Start the timer. Visually read results at 15 minutes. Do not interpret results after 30 minutes.
