What do you need to go to CDC for nucleic acid testing

1. Do nucleic acid detection must ensure that a sufficient sleep, do not stay up late, and do not eat two hours before the detection, so as not to cause vomiting, and try not to smoke, and drink. We should also be psychologically prepared, not too nervous, not too much psychological pressure. After the detection, you can wait for the results. Generally, many of the results will send messages, most of them can come out in about 7 working days, and the accuracy of the inspection results is relatively high
according to the situation you described, you can apply for nucleic acid testing according to the domestic situation, and you don't need to prepare anything
suggestions: after nucleic acid testing, you can usually be informed of the results in about 48 hours. Of course, if you have symptoms or contact with people in the epidemic area, you can check, otherwise it is not recommended
nucleic acid testing is an effective way to determine whether the tested personnel are infected with the new coronavirus. With the tide of returning to work, many people have recently gone to hospitals, centers for Disease Control and prevention and other institutions for nucleic acid testing. So what should we pay attention to before nucleic acid detection? Can we drink and eat? Let's get to know

I. precautions for nucleic acid detection
1. Avoid collection within 2 hours after eating to avoid vomiting< No smoking, such as drinking, chewing gum, etc. 30 minutes before sampling

3

4. Never touch the swab sampling crown (front end of swab) with hands or other objects at any time

7. When taking throat swab samples, take off the mask, fold and package it in a plastic bag and put it in the pocket

8. Wash hands or wipe hands with wash free alcohol immediately after sample collection, put on spare masks, and put the discarded masks into the designated medical garbage can.

2. 1. For nucleic acid testing, you need to bring your ID card, health code and medical insurance card to the testing point to wait in line. Along the way, there are staff to disinfect from time to time, and volunteers to guide you. Remember to wear masks and keep a distance ring the whole process
2. In the process of queuing, you can scan the code by mobile phone. Enter the nucleic acid detection registration page and fill in the basic personal information.

3.

To use ID card real name registration, and then to fever clinic or designated hospital application for nucleic acid testing

nucleic acid was mainly detected by throat swab sampling. That is to say, use a soft cotton swab (a special collection tool for throat swab) to continuously rotate in the posterior pharyngeal wall and bilateral tonsils, and then put it into the test tube after obtaining obvious secretion, tighten the cover of the test tube, and then pack the test tube in a sealed bag

the sealed collected sample tubes should be stored at low temperature and sent for inspection as soon as possible. Nucleic acid detection is an important means for New Coronavirus to diagnose and screen. Novel coronavirus pneumonia: p>

extension:

note:

, the State Council, the new comprehensive prevention and control mechanism for the new crown pneumonia epidemic prevention and control mechanism, has recently issued the "Implementation Opinions on accelerating COVID-19 nucleic acid detection" (hereinafter referred to as the "implementation opinions") to guide all regions to do well in nucleic acid detection in normal prevention and control work. p>

the "implementation opinions" put forward to speed up the improvement of nucleic acid detection ability, and try to expand the scope of nucleic acid detection as the primary measure for the implementation of the four early measures of normalized prevention and control. It is clear that 8 kinds of key groups should be examined as much as possible

4. When you go to the hospital for nucleic acid detection of new coronavirus pneumonia, the main items you need to carry are your ID card or other valid documents; Medical protective mask or disposable mask, it is best to prepare a spare. If there are conditions, hand disinfectant can be prepared at any time. In the process of detection, it should cooperate with the command of medical staff, and the distance between other patients should be at least one meter
nucleic acid is the nucleic acid of virus. Nucleic acid detection is to find out whether there is foreign virus nucleic acid in respiratory tract samples, blood or feces of patients to determine whether they are infected by new coronavirus. Therefore, once the detection of nucleic acid "positive", it can prove that there is a virus in the patient's body
after the new coronavirus infects the human body, it first propagates in the respiratory system, so we can determine whether the human body is infected with the virus by detecting the viral nucleic acid in sputum and nasopharyngeal swab. Therefore, the positive detection of nucleic acid can be used as a gold standard for the diagnosis of New Coronavirus infection.
all organisms except prion contain nucleic acids, nucleic acids including DNA and RNA. New Coronavirus is a virus that contains only RNA. The specific RNA sequence in the virus is a marker for distinguishing the virus from other pathogens. After the appearance of New Coronavirus, Chinese scientists completed the analysis of the whole genome sequence of New Coronavirus in a very short time, and discovered the specific nucleic acid sequence in New Coronavirus by comparing with the genome sequence of other species. In the process of clinical laboratory testing, if the specific nucleic acid sequence of New Coronavirus can be detected in patients' samples, it should be suggested that the patient may be infected by New Coronavirus.

5. We Tonghua do nucleic acid detection, with personal ID card can do nucleic acid detection.

6. Nucleic acid detection process is about 2-4 hours. The nucleic acid detection of new coronavirus is based on the national plan, and the method is real-time fluorescent RT-PCR. For this method, half an hour is impossible, and the net operation time of this experiment needs about 2-4 hours
at the sampling site, under the guidance of the medical staff, the sampled persons need to register their name, gender, age and other information. If necessary, they need to cooperate with the medical staff to verify their identity. After registration, the samples are collected
dry cough or vomiting may occur in the process of throat swab sample collection, therefore, in order to protect the collector and the collected, and prevent cross infection, the collection personnel should do three-level protection, and collect specimens in a well ventilated environment. In good weather, they can choose outdoor

method / step
1 / 6 step by step reading
the first step is to collect secretions
first of all, the medical staff will use a throat swab to wipe the nasal cavity or throat tonsil of the subject to collect saliva secretion, which is actually quite painful

2 / 6
the second step is to keep the sample
after the human secretion is collected, the throat swab is immersed in the preservation solution, and the tube cover is screwed for sample retention

3 / 6
the third step is to send samples for inspection
then, the samples are put into a clean sealed bag, sealed and sent to the relevant parts for testing< The fourth step is nucleic acid extraction
the relevant departments will send the samples to the designated laboratory for nucleic acid extraction experiment

5 / 6
the fifth step is fluorescence PCR nucleic acid detection
after the nucleic acid is extracted, fluorescent PCR is used to detect whether there is amplification reaction, that is, to judge whether it is negative or positive

6 / 6
finally, the nucleic acid detection report was proced
finally, according to the fluorescent PCR reaction results of nucleic acid detection, the nucleic acid detection vehicle report can be obtained, and I can query the results.

The new coronavirus is terrible. Now we are trying our best to find and find the source of infection, and find the infected by nucleic acid testing. So what is the process of virus nucleic acid testing? How much does it cost? In this paper, we will briefly share the knowledge in this aspect:

and then put the sample tube into the sealed bag for inspection. In this process, it needs to be stored at 2-8 ℃. At first, the virus was inactivated and then nucleic acid was extracted. Finally, fluorescent PCR amplification and nucleic acid detection were performed. The whole process takes about 6 hours, if the first test result is "positive", it needs to repeat the operation again for review, so a positive report needs at least 12 hours. Because the nucleic acid detection process is very high-risk, so the sampling doctors should take more strict protective measures. In addition to a full set of protective clothing, they also need to add a head cover. All the parts above the shoulder are in the head cover. There are many and complex tasks for the laboratory doctors to do in the testing room, with a total of more than ten steps. The main operator often has to keep his hands hanging for several hours, and can not easily leave the operating platform. In this epidemic, the detection of viral nucleic acid is a very urgent task. In the face of many nucleic acid samples that need to be detected, the laborious work of the laboratory doctors is self-evident. It can be said that through the above introction, we must pay tribute to these respectable doctors in the epidemic

8. Zhoupu hospital revealed that according to relevant regulations, informed consent should be done before sampling, and personal information should be carefully checked and registered; During sampling, biological sample transportation and laboratory testing should be carried out in strict accordance with the relevant national and Shanghai biosafety management requirements. Personal protective measures should be implemented for sampling personnel to ensure "one person, one collection", disinfection and isolation of places, and disposal of medical wastes; After sampling, after the designated third-party testing institutions carry out the test, the hospital will issue the test report. For the objects with positive results, the relevant information must be reported to the CDC at the first time
from the current situation, the appointment of personal nucleic acid testing service is very popular, and some hospitals have also met many patients who have recovered from cough and fever, so they want to do a test to eliminate their doubts. So, do ordinary people have to do nucleic acid testing< The answer, of course, is No. If an ordinary person has no respiratory symptoms, no fever, and no epidemiological history, there is no need to do nucleic acid testing. Wu Zunyou, chief epidemiologist of China Center for Disease Control and prevention, said in an interview with CCTV: "it is very necessary to expand the scope of detection and find early patients as soon as possible, but nucleic acid detection is not necessary for everyone. Before detection, a risk assessment can be made, and those from high-risk areas, overseas and those with close contact history of infected people can do it."
according to the introction of the applicable population of indivial nucleic acid testing, including overseas entry personnel, returning to school personnel, enterprise returning to work personnel and asymptomatic personnel who need to go abroad, etc. However, major medical institutions also remind that nucleic acid testing is a medical behavior, not a consumer behavior, and ordinary people need not worry too much about themselves. If you have fever or other respiratory symptoms, you should go to the hospital fever clinic for investigation, and the medical staff will give a diagnosis. Therefore, the public should treat it rationally. If there is no risk and demand, they do not need to go to the hospital to join the fun.
