There are no test strips related to the new crown nucleic acid test sold in pharmacies. Nucleic acid test strips are not available at pharmacies, but some pharmacies may be able to buy neoguana antigen test kits. For example, during an outbreak, residents can purchase a neoguana antigen test kit at a community healthcare facility or pharmacy to initially screen themselves for neoguana infection. First of all, nucleic acid testing is a detection technology, its main steps can be divided into nucleic acid sample sampling, laboratory testing, results determination of the three major steps. Nucleic acid laboratory testing steps include nucleic acid extraction, nucleic acid amplification and other steps and procedures. Nucleic acid extraction is the use of various reagents from the collection of samples to extract the nucleic acid structure of the pathogen, and then in the PCR instrument or other instruments for amplification, according to the results of the amplification of judgment. The New Crown Antigen Test Kit offers some simplicity, but nucleic acid testing is still required to confirm the diagnosis of New Crown virus infection.
