Nucleic acid testing mainly has oropharyngeal swab, nasopharyngeal swab, anal swab, serum antibody test these ways, Shenzhen Huarui Kang Biomedical Technology Co.
Oropharyngeal swab
When sampling oropharyngeal swabs, you need to open your mouth to make the "ah" sound and take out a sterilized cotton swab to gently and quickly wipe the lateral wall of the pharynx and the posterior wall of the pharynx several times.
It is relatively simple and less irritating and suitable for mass screening.
Nasopharyngeal swab
For nasal swab sampling, the swab is inserted into the nostril in a vertical nose (face) direction until the fingers are close to the nose, so that the swab stays in the nose for 15-30 seconds, and then gently rotated 3 times.
High technical requirements, human body feels uncomfortable, higher accuracy than oropharyngeal swab
Anal swab
High accuracy, reduces missed diagnoses, targets key populations such as isolation sites
Serum antibody test
Detects antibody levels in human blood
Early stage of disease infection, human body may not have antibodies and there is a window period for detection.
Aids in diagnosis for nucleic acid testing, and additional testing for key populations if necessary.
