Nasal swab test

 A nasal (or nasopharyngeal) swab is used to diagnose upper respiratory tract infections, such as whooping cough and COVID-19. It is a quick test that may feel a little uncomfortable but is not painful.

In this test, secretions from the back of your nose and upper throat are collected using a swab. Sometimes, a suction device may be used to gently remove the secretions. This is known as a nasal (or nasopharyngeal) aspirate.

The secretions are sent to a laboratory where they are grown. This makes it easier to identify which viruses, bacteria or fungi are present. The results are sent back to your doctor who will use them to help diagnose what germs could be causing your symptoms.

How is a nasal swab done?

To do a nasal swab, a small, soft-tipped swab will be inserted into one or both of your nostrils and twirled a few times until it is covered in secretions. Only a single swab is taken for COVID-19 testing.

The swab will be inserted quite a way in to get to the area that will give the best result. This may be a little uncomfortable but should not be painful. 

How is a nasal aspiration done?

If your doctor uses the nasal aspiration method, a small tube will be inserted into your nostril. This tube is connected to a suction device, which gently removes secretions from your nose. This will be repeated on the other nostril.
