Nucleic acid test currently refers to the new crown nucleic acid test, a small number of people do nucleic acid test can be dry and nausea and other reactions, the majority of people can tolerate the sampling operation, and there is no obvious relationship with gender.
The reason for dry heaving is that the sampling site is located in the posterior pharyngeal wall and the pharyngeal mucosa, during the sampling process, the cotton swab will form a stimulus to the site, thus triggering the pharyngeal reflex, which in turn manifests as nausea and dry heaving.
Whether or not dryness and nausea occurs during nucleic acid testing has no obvious relationship with gender, but is mainly related to the depth of the sampling site, the severity of the sampling and the sensitivity of the pharyngeal reflex of each individual.
Dry heaving after sampling is also a normal physiological reaction of the human body, and can be recovered after a few minutes, so there is no need to be too nervous about it. It is recommended that you do not eat for 2 hours prior to sampling, and that you remain relaxed and cooperative during sampling.
If the discomfort is not relieved after the test, inform your healthcare provider promptly.
