We all know that nucleic acid testing requires the extraction of secretions from the throat, especially when the swab is rubbed in the back of the throat, causing some irritation, and some people with a sensitive throat may experience nausea and vomiting, so what can we do to avoid nausea?

First of all, it is best to avoid eating 2 hours before the nucleic acid test to avoid food reflux during the test, which can cause nausea and vomiting; secondly, it is best not to smoke or drink for 8 to 12 hours before the nucleic acid test, which can effectively prevent the stimulation of the throat and thus reduce the incidence of nausea and vomiting. Finally, patients are advised to relax and not to have too much stress before sampling, which can reduce the incidence of uncomfortable reactions. And after the collection should also drink more water, light diet, avoid eating spicy and stimulating, greasy food, prohibit smoking and alcohol, so that it does not take long to return to normal, if you really can not stand it, you can also communicate with the testing agency, choose to change to blood specimens for testing.

There are also some partners asked, nasal swabs and pharyngeal swabs which will be more painful?

Generally speaking, the nasal swab will be more uncomfortable. Because the pharyngeal swab is tested by dabbing the secretions from the throat with a cotton swab, the patient may just experience nausea and vomiting during the process. For the nasal swab, it is necessary to insert the nasal swab deep into the nasal cavity and dip the secretion for testing, so in this process, the patient may have a stronger painful reaction, and this pain lasts longer, and for some people with fragile nasal mucosa may also have the symptoms of nosebleed.

Will the nucleic acid test be positive if I have a cold?

The nucleic acid test is usually not positive when you have a cold. Because the nucleic acid test is specific, mainly for the detection of the new coronavirus nucleic acid, for other types of viruses can not be detected, so if it is just a common cold, through the new coronavirus nucleic acid test will not generally be positive. But because the common cold may also be rhinovirus infection, so if other testing methods are used, the test result may also be positive. Back to search, see more
