What kind of person is not suitable for nucleic acid testing?

What kind of person is not suitable for nucleic acid testing? Many people pay more attention to COVID-19. The main method to judge whether there is COVID-19 is nucleic acid testing, but not everyone can do it. Let's share what kind of people are not suitable for nucleic acid testing. Let's take a look.

What kind of people should not be tested for nucleic acid 1 First of all, people who smoke, drink alcohol and chew gum should not be tested for nucleic acid 30 minutes before sampling. , so as not to affect the accuracy of detection.

Second, people who eat too much should not do nucleic acid testing, otherwise they will be prone to nausea and vomiting, which will affect the accuracy of the results.

Third, nucleic acid testing Before oral antiviral and anti-infective drugs are taken, nucleic acid testing should be postponed so as not to affect the test results.

Four, if the nasal swab sampling, for the acute phase of nasopharyngeal diseases, such as bleeding, edema and other people can not be tested for the time being.

Five, just in the nucleic acid detection of nausea and vomiting, should suspend nucleic acid detection, until the tester to alleviate.

6. The sampled person touches the sampling crown of the cotton swab and the front end of the cotton swab by hand or other objects. Not desirable, otherwise it will easily cause pollution and affect the test results, so it needs to be replaced and redone.

What kind of person is not suitable for nucleic acid testing? 2 people who are not suitable for nucleic acid testing

1, people who eat too much should not do nucleic acid testing to avoid nausea and vomiting and affect the accuracy of the results.

2. People who smoke, drink or chew gum 30 minutes before sampling should not do nucleic acid detection, so as not to affect the accuracy of detection.

3. The sampled person should not touch the sampling crown and the front end of the cotton swab with his hands or other objects, so as to avoid pollution and affect the test results, and should be replaced and redone immediately.

4. Oral antiviral and anti-infective drugs before nucleic acid testing may affect the results of nucleic acid testing, so it is not appropriate to do nucleic acid testing for the time being.

5. If nasal swab sampling is carried out, the acute phase of nasopharyngeal diseases, such as bleeding and edema, can not be detected for the time being.

6. People who have just experienced nausea and vomiting in nucleic acid testing should suspend nucleic acid testing and wait for the tester to relieve discomfort.

Can nucleic acid detection be done during a cold?

Disease analysis: nucleic acid detection can be done during a cold, and the result will not be affected when a cold occurs. It is suggested that you can go to the hospital for throat swab nucleic acid examination and chest ct examination to determine whether you are infected with novel coronavirus. The patient needs to be isolated until the test results come out. People with colds should drink more hot water and keep warm. Don't go to crowded public places during this time. When the cold symptoms are serious, it can be treated with Ganmaoling granules or compound paracetamol and amantadine capsules under the guidance of a doctor. It is best to eat light food such as millet porridge.

Does the nucleic acid test start from the nose or the mouth?

Both will do.

When detecting nucleic acid, it can be taken from nasal cavity or oral cavity. This method is called nasopharyngeal swab.

Generally speaking, specimens taken from the oral cavity are called throat swabs. Whether it is a nasopharyngeal swab or a throat swab, the results are accurate. No matter what kind of specimens, nucleic acid test results are positive, can be diagnosed as novel coronavirus infection.

However, novel coronavirus's nucleic acid detection has some limitations. If the result of nucleic acid test is negative, it doesn't mean that it's all right, and sometimes there will be false negatives, which is why the nucleic acid test may be repeated for a patient in novel coronavirus.

Which is more accurate, throat swab or blood drawing?

Both are accurate, but the accuracy of blood drawing is higher.

As long as it is carried out in a regular hospital, both throat swab and blood collection are accurate. However, considering that throat swabs are greatly influenced by external factors, blood sampling to check pathogens and screening among tens of thousands of pathogens are less influenced by external factors, and although it takes a long time, the accuracy will be more accurate than throat swabs.

What should I pay attention to when doing nucleic acid testing?

First, before testing:

(1) Avoid eating 2 hours before nucleic acid test to avoid vomiting;

(2) Do not drink (including drinking water), smoke, drink or chew gum 30 minutes before sampling;

(3) reduce swallowing action and not clear throat (such as expectoration and spitting);

(4) Before collecting nasopharyngeal swab, the examinee should inform the collector whether there is any relevant past history or related matters. For example, the history of nasal surgery, curved nasal septum, blood diseases, throat diseases, or taking anticoagulants and other related risk factors;

(5) Testers should wear masks correctly, take them off before testing, put them on immediately after testing, and prepare spare masks for replacement at any time after pollution.

Second, in the test:

(1) When collecting oropharyngeal swabs, the examinee leans back and opens his mouth to make an "ah" sound, which helps to expose his throat, but there will be irritating dry cough, nausea, vomiting and other symptoms during the process. The examinee can cooperate with the collector to relax and take a deep breath as much as possible;

(2) There may be itchy nose and sneezing in the process of collection. You can immediately cover it with paper towels (prepared in advance) or elbows;

Third, after testing:

(1) Leave the assembly site immediately after assembly to avoid spitting and vomiting around the assembly site;

(2) Attention should be paid to hand hygiene before and after nucleic acid detection, and hands can be wiped with hands-free disinfectant or alcohol.

(3) In addition, in order to improve efficiency, you can make preparations in advance: you may not hear clearly because of the strict protection of medical staff. At the same time, in order to improve efficiency, please be sure to bring your ID card or household registration book, wear a mask (it is best to wear two, one of which is spare) and bring a tissue (collection may cause discomfort and tears). You can write a note in advance.
