Specimen Requirements:
Nasopheryngeal specimen in a Blue Capped mini-tipped E-Swab® (with Liquid Amies)
Collection Instructions:
Swab tips may be polyester, rayon, nylon flocked. Flexible shafts must be used for proper collection. Accuracy of the test depends on the collection of ciliated epithelial cells material. Half the distance from the nostril to the base of the ear could be used as estimation of the site of collection. Gently insert swab into the nostril. Keep the swab near the septum floor of the nose while gently pushing into the posterior nasopharynx. Rotate swab 2-3 times and hold in place for few seconds for optimal collection. Collection of both nostrils is recommended but not required.
