What procedure does nucleic acid test need to Yantai CDC
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
5
6
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. 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.
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
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.
Do nucleic acid test with ID card
in the early stage of virus invasion, the amount of virus in human body has not reached the detectable level. The viral load of different parts of human body (such as nasopharynx, oropharynx, trachea, bronchus and alveoli) will be different in different periods of virus incubation, mild symptoms and severe symptoms. Therefore, different sampling time and location may lead to insufficient virus in the collected samples
