How long does it take to do a nucleic acid test? How to do nucleic acid testing?

1. If you do not make an appointment online, you need to register first

2. Fill out the commitment letter at the door and sign it

3. Conduct epidemiological history screening

4. Queue up and enter the screening clinic to register

5. Consult a doctor and choose the items to be screened

6. At the sampling office outside the clinic Blood collection or throat swab collection, the sampling process can be completed in about one or two minutes

Reminder: Results are usually available within 24 hours.

What are the steps for nucleic acid testing?

1. The first step is to collect human body secretions and wipe the nasal cavity or posterior pharyngeal wall and bilateral pharyngeal tonsils with a nasal swab or throat swab.

2. The second step requires medical personnel to retain the sample, immerse the swab head in the cell preservation solution, break off the tail and tighten the tube cap immediately.

3. In the third step, the sample tube needs to be placed in a sealed bag, stored and sent for inspection in a timely manner.

4. The fourth step requires sending the sample to the laboratory for nucleic acid extraction.

5. The last step is to perform fluorescent PCR nucleic acid detection and perform fluorescent PCR amplification reaction on the extract.

How much does it cost to do a nucleic acid test?

Prices vary slightly from place to place. According to reports, a nucleic acid test generally costs 200-300 yuan.

Do ordinary people need to undergo nucleic acid testing?

If an ordinary person has no respiratory symptoms, no fever, and no epidemiological history, then he does not need to undergo a nucleic acid test. However, if he has respiratory symptoms such as fever, or has an epidemic in a key epidemic area, If you want to study history, you can go to the fever clinic of the nearest hospital to get a nucleic acid test.

What is the principle of nucleic acid testing?

Nucleic acid is a type of biopolymer in the nucleus of a cell. It is a biochemical component of all known life. It participates in biochemical synthesis and cell metabolism such as the preservation and reproduction of genetic material, and determines the function of cells or organisms. Character performance. Viruses, as the simplest living organisms, are composed of nucleic acids and proteins.

The nucleic acid of each organism is different. The purpose of nucleic acid testing is to determine whether a person has the virus, that is, to detect the carrier of the virus. If a virus carrier has symptoms, he is a patient; if he has no symptoms, he is an asymptomatic infection.

Will nucleic acid tests be conducted on students after the school reopens?

If financial resources permit, it is necessary for schools to conduct nucleic acid tests on students. Nucleic acid testing of students can help promptly detect and isolate the source of infection and cut off the transmission route, thus facilitating the prevention and control of the epidemic. Of course, it is more important to conduct an epidemiological history investigation, such as whether any students or teachers have close contacts with COVID-19 cases, or whether they have relevant travel or residence history in areas hardest hit by the epidemic, etc. In addition, in a relatively closed environment like a school, it is necessary to fully implement personal protection measures, wear masks, wash hands frequently, and maintain a safe distance.
