The Xiangcheng County Center for Disease Control and Prevention reminds you:
What do I need to pay attention to when testing for nucleic acid?
01
Will drinking the day before affect the test results?
A: No.
Try to avoid eating 2 hours before the nucleic acid test to avoid vomiting. Do not smoke, drink alcohol, or chew gum 30 minutes before sampling to avoid false negative results.
At present, most of them use oropharyngeal swabs, and the inspectors use a swab similar to a cotton swab to wipe the posterior wall of the pharynx and bilateral tonsils, and the samples are collected and sent to the laboratory. In line with the attitude of being responsible for the overall situation of epidemic prevention and control and being responsible for my own health, please cooperate with the relevant provisions of nucleic acid testing, standardize the collection of throat swab samples, and avoid various behaviors that may affect the test results.
02
Having laryngitis, does having sputum in the throat affect the test results?
Its etiology is mainly caused by recurrent episodes of acute pharyngitis, irritation of inflammatory secretions from the sinuses of the nasal cavity and nasopharynx, direct spread of chronic inflammation of the tonsils or excessive tobacco and alcohol, dust, harmful gases, air pollution and other irritations and excessive consumption of spicy foods. The new crown nucleic acid detection is a specific test, which is the performance of the new crown virus infection, so it will not affect the test results.
03
Will a cold affect test results?
Coronavirus-specific RNA sequences are markers that distinguish the virus from other pathogens. If the symptoms of upper respiratory tract infection are not caused by the new crown virus, the kit will not accumulate a sufficient amount of immunofluorescence, and the specific nucleic acid sequence of the new crown virus will not be detected in the patient sample, so there is no need to worry about being "misjudged".
When citizens with upper respiratory symptoms go to check for nucleic acid, they should wear masks correctly according to regulations, maintain a safe interpersonal distance from others, avoid conversations, and cover coughs with tissues or elbows to reduce the risk of droplet transmission.
04
Do children also have to do nucleic acid testing? How?
A: To be done.
Children are also at risk of COVID-19 and should also be tested for nucleic acid. For children without relevant identification, a guardian ID can be provided for registration.
If the baby is too young to cooperate with the health care worker to take samples, parents can pinch the cheeks on both sides of the baby slightly and take a throat swab after the baby opens his mouth. However, do not forcibly break your mouth to avoid causing harm to the baby's mouth, while aggravating the child's fear and affecting the sample collection.
05
Do I have to do a nucleic acid test on an empty stomach?
A: No fasting is required.
However, try to avoid eating 2 hours before the nucleic acid test to avoid vomiting. Do not smoke, drink alcohol, or chew gum 30 minutes before sampling to avoid false negative results.
06
After the nucleic acid test has been done for more than 24 hours, and the test results have not been found, will it be positive?
A: Due to the current nucleic acid testing drill for all employees, the number of tests is large, and the sampling and testing personnel are already working at full capacity, so the negative results of collective sampling are not issued for the time being. If the test result is found to be positive, the individual will be notified as soon as possible. If you don't receive a test result, you don't have to worry too much.
