A sterile suction catheter is attached to a specimen container and light suction is applied while rotating and removing the catheter. Several drops of sterile 0.9% sodium chloride are placed into the nostril. A nasopharyngeal specimen may also be obtained using a wash method. 4 The swab should be left in the nostril for several seconds to absorb as much moisture as possible. Obtaining a simple nasopharyngeal swab is completed by inserting the specimen swab into the nostril approximately half the distance between the patient’s nostril and ear. 3 The same swab is then used in the same manner in the other nostril. A nasal midturbinate specimen is obtained by inserting the specimen swab straight back into the nostril approximately 2 cm (0.8 inch), or until resistance is felt. 1 The same swab is then used in the same manner in the other nostril. 1 The swab is rotated for a total of 15 seconds.

The test results help determine which antibiotic therapy or treatment is appropriate. Other organisms, including Haemophilus influenzae, Streptococcus pneumoniae, and Candida albicans, are considered abnormal if found in large amounts. Pathogenic organisms that may be identified by culture include group A beta-hemolytic streptococci, Bordetella pertussis, Corynebacterium diphtheriae, and Staphylococcus aureus. To determine the degree of infection, laboratory personnel place the specimen in a transport media and determine if pathogenic organisms grow.
