Collection Instructions

Nasopharyngeal Swab Method (Preferred)
Use only synthetic fiber swabs with plastic shafts. Do not use calcium alginate swabs or swabs with wooden shafts, as they may contain substances that inhibit PCR testing.

1.) Carefully insert swab into the nostril parallel to the palate.
2.) Rotate swab over surface of posterior nasopharynx, keeping the swab in the nasopharynx for several seconds to absorb secretions.
3.) Slowly withdraw swab from collection site
4.) Insert immediately into sterile tube containing 3mL transport media. You will need to break off or cut the swab shaft to fit in the vial.
5.) Securely close the vial.
6.) Label vial with specimen identification label or hand label. Specimen must be labeled with last name, first name and date of birth.
7.) Place each vial in a separate, individual specimen transport bag. Seal the zip lock. Place folded paper requisition in the outer front pocket of the transport bag.
