All about the Nasal Swab
Nasal Swab:nasopharyngeal np swab.
The specimens collected from nucleic acid samples are mainly pharyngeal swabs, which are divided into “nasopharyngeal swabs” and “oropharyngeal swabs“.
Nasopharynx swab and oropharyngeal swab only have different sampling paths. Oropharyngeal swab is to collect oropharyngeal specimens by entering the sampling swab through the mouth, and nasopharyngeal swab is to collect nasopharyngeal specimens through the nose.

Nasopharyngeal swab sampling method.
Hold a swab close to the nostril to enter, and slowly go deep along the bottom of the lower nasal tract.
Since the nasal tract is curved, do not use too much force to avoid trauma and bleeding.
When the top of the swab reaches the posterior wall of the nasopharyngeal cavity, rotate it gently for one week (stay for a moment in case of reflex cough), then slowly take out the swab and immerse the swab head into a tube containing 2 ~ 3ml virus preservation solution.

How to take a swab sample?
Ask the patient to take off the mask and blow his nose with a paper towel to remove excess secretions from the nasal cavity. Remove the swab from the package.
Tilt the patient’s head back slightly to make the nasal passage easier to pass through. Ask the patient to close their eyes to reduce the mild discomfort of the operation.
Gently insert the swab over the bottom of the nasal canal along the nasal septum until the nasopharynx stops when resistance is felt.
Insert the cotton swab parallel to the upper jaw into the nostril.
If you feel resistance when passing, step back and try to reinsert it at another angle to bring it closer to the bottom of the nasal canal.
The depth of the swab should be equal to the distance from the nostril to the opening outside the ear.
CDC recommends placing the swab for a few seconds to absorb enough secretions, and then slowly removing it while rotating the swab.
Some organizations may also recommend rotating the cotton swab several times before taking it out.
After removal, ask the patient to put on the mask again.
Specimen processing
Open the virus transport medium and insert the swab into the collection tube.
Break the swab at the groove and discard the remaining part. Seal the labeled collection tube and place it in the biohazard garbage bag.
According to convention, you can return the sample to its original packaging for disposal.
Follow CDC instructions for direct treatment of swab specimens or place swabs in medium with or without refrigeration.
