Step 1

Disinfect surfaces where you will be completing your test.Blow your nose.Then thoroughly wash your hands with soap and water for 20 seconds prior to collection.

Step 2

Before inserting the swab，locate the perforation on the swab（near the tip）as you will need this after you collect your sample.Then tilt your head back to approximately a 45 degree angle.

Step 3

Let the nasopharynx swab passes through the nostril. It goes deep perpendicular to the coronal plane of the head or the face, from the lower nasal meatus to the posterior wall of the nasopharynx, and has the feeling of touching the wall. The depth of the nasopharynx swab into the nasal cavity is about the distance from the tip of the nose to the earlobe.

Step 4

According to the guidelines for clinical microbiological specimen submission of the American Society of Microbiology, the nasopharyngeal swab should be twisted on the nasopharyngeal mucosa, kept for 10-15 seconds, and then removed. Children's cooperation is poor. In practice, we usually take out the swab after 2-3 twists.
