At the moment of the epidemic, many people have been notified of nucleic acid testing, and health protection has become the topic of most concern to everyone. Why not “ah” when doing nucleic acid testing? How to avoid the risk of infection during testing? Now, let’s learn about it together.
Drinking a drink before nucleic acid,
will cause a “false positive”?
“Do not drink water and rinse your mouth before doing nucleic acid, eat fruit, pickles, drink carbonated drinks, and wine, all are prone to false positives.” Recently, many people have received such a ” hint”.
In this regard, Li Tong, chief physician of the Department of Respiratory and Infectious Diseases of Beijing You’an Hospital, once said that there is no scientific basis for the claim that diet causes false positives of nucleic acids.
Li Tong once said that whether it is nucleic acid testing or antigen testing, there is a certain probability of false positives. In contrast, nucleic acid testing is affected by fewer factors, and the probability of false positives is very low. There is no overall pattern in the occurrence of false positive results, mostly caused by laboratory contamination or improper operation.
“We will remind citizens not to eat within 2 hours before the nucleic acid test, not to drink water for half an hour in advance, especially carbonated drinks, alcohol, and not to smoke or chew gum. Li Tong once said that this kind of prompt is mainly to avoid “false negatives” during the nucleic acid detection process. He explained that drinking water, drinking beverages, etc., will dilute oral secretions, which may lead to inaccurate test results. “Of course, this is also to prevent citizens from experiencing nausea and vomiting during the nucleic acid sampling process.”

Why don’t “ah” come out when doing nucleic acid?
Some experts suggest that during the nucleic acid detection process, it is best not to “ah” out. Why is this?
Li Tong once explained that “ah” is an exhalation action. If a positive patient exhales during the nucleic acid test, more virus will be excreted. Therefore, do not “ah” out, to protect others.
How to better protect yourself during the collective nucleic acid testing process? Li Tong once suggested that after taking off the mask, try not to take a deep breath. “Before taking off the mask, you can take a breath. After taking off the mask, cooperate with the staff’s instructions to open the mouth as much as possible, and make sure the movements are in place, so that the staff can take samples in one step, and quickly put on the mask after picking.” Li Tong once said that this action can be practiced in advance before doing nucleic acid.
“To do nucleic acid collectively, the most fearful thing is to gather and talk.” Li Tong once said that citizens should keep a distance of more than one meter when queuing, and do not gather or drink No water, no food, especially no face-to-face conversations. When the sampling of the person in front is over, wait for the instructions of the staff, do not sit down or take off the mask and wait, and try to reduce the time for taking off the mask as much as possible.
During the nucleic acid sampling process, do not put items on the table, and do not touch the table with your hands. Wash your hands in time and keep your hands hygienic when you go home after finishing the nucleic acid. “You can prepare an alcohol wipe in advance and disinfect your hands immediately after the nucleic acid is done.”
The mask in the end How often to change?
How often should masks be replaced? Is it possible for used masks to cause pollution?
Li Tong once said that masks need to be replaced after 4 to 6 hours of continuous use. If it is not used continuously, you can calculate the accumulated usage time as appropriate. “Of course, if the mask is wet, soaked, or dirty, it needs to be replaced immediately.”
When removing the mask midway, it is best to find a clean plastic bag or a piece of clean paper Wrap it up, or find a ventilated place to hang it.
“Don’t put used masks in your pockets or school bags, so as not to contaminate masks and contaminate items.” Li Tong once said.
Participate in large-scale nucleic acid detection,
What to watch out for?
before nucleic acid detection
It is recommended not to eat within two hours, and not to drink water, alcohol, or chewing gum 30 minutes in advance to avoid vomiting and nausea that may occur during the sampling process.
Wear a mask, do personal protection, and maintain social distance. Follow the arrangements of the on-site staff, queue up consciously and orderly, and do not chat with others.
During the inspection process
Avoid touching the items on the inspection table, and do not put mobile phones, ID cards, keys and other personal items on the table.
Whether it is a nasal swab or an oropharyngeal swab, corresponding actions must be taken in accordance with the requirements of the medical staff to avoid cross-infection.

After the nucleic acid test
Wear the mask and leave immediately, do not stay at the sampling site for too long.
Do not discard waste at the sampling point, and continue to take personal protection and hand hygiene after sampling.
Order queue not crowded
Don’t gather when you’re done
Don’t slack on personal protection
Work together to win< /p>
