New Crown Virus Antigen Test Strips for throat stabbing are OK, but you need to purchase the throat swab version of the antigen test strips. New Crown antigen detection test strips are known as New Crown self-test kits. There are nasal swabs for sampling and pharyngeal swabs for sampling. If you need to test by poking your throat. You can purchase the pharyngeal swab version of the New Crown self-test kit according to your needs. Nasal swab sampling is generally a little more accurate because the nasal cavity will have a higher viral load than the throat. The New Crown Self-Test Kit utilizes the principle of antigen-antibody reaction to detect the presence of viral proteins in the collected sample.

Hands should be cleaned before antigen detection test strips and the instructions should be strictly followed.
