What is the difference between a nucleic acid test throat swab sample and a nasal swab sample?Is it necessary for these two sampling methods to be carried out simultaneously?
Shi Guoqing, an expert from the National Health Commission and deputy director of the Emergency response center of the China CDC, said there is no difference in essence between oropharyngeal swabs and nasopharyngeal swab collection, both of which are for pharyngeal specimens to be tested for infection, and nasal swabs are slightly less acceptable to the public.There are other factors affecting the sample detection rate, such as the sampling time of the disease. The positive sample detection rate is relatively high within one week after the onset of the disease, and the detection rate will decrease after more than 10 days.It is generally not necessary to carry out both sampling methods simultaneously.
