How long did it take to do COVID-19 nucleic acid test in the hospital in Beijing in the morning?

The results usually come out within 24 -48 hours. Some hospitals produce results 24 hours a day, and some hospitals produce reports 36 hours a day, depending on the notice of each hospital.

Sampling method:

1, rinse your mouth with water before sampling.

2, packaging, take out the tear swab preservation solution and the sample bag.

3. Open your mouth and pronounce "ah" to show your throat.

4. Wipe bilateral pharyngeal tonsils and posterior pharyngeal wall 5 with a cotton swab. Save the swab head in the sampling tube and indicate personal information.

Principle of nucleic acid detection

All living things contain nucleic acids, including DNA and RNA. Novel coronavirus is a virus containing only RNA, and the specific RNA sequence in the virus is a sign to distinguish it from other pathogens.

After the appearance of novel coronavirus, Chinese scientists completed the analysis of the whole genome sequence of novel coronavirus in a very short time, and found the specific nucleic acid sequence in novel coronavirus by comparing with the genome sequences of other species.

If novel coronavirus's specific nucleic acid sequence can be detected in patients' samples during clinical laboratory testing, it should be suggested that patients may be infected by novel coronavirus.
