This is a brief list of oral and nasopharyngeal specimen collection procedures. MRSA Location: Anterior nares Swab: Routine cotton culture swab VIDEO
Top Influenza Location: Posterior nasopharynx Swab: Routine cotton culture swab Wear a surgical mask, protective eye wear and gloves while collecting the specimen Place the patients head on the bed pillow or against a wall so that they do not move backwards The swab will go straight backwards like placing an NG tube, it should go the distance between the nostril and the ear into the throat. The swab is rotated for a bout 5–10 seconds to get enough epithelial cells on it Remove the swab and place it in the transport media and sent it to lab
The PCR assay reuires a special swab, made of aluminum with a nylon tip.
Traditional cotton tip swabs interfere with the test Location: Posterior nasopharynx A special transport media is needed- call the lab for it Wear a surgical mask, protective eye wear and gloves while collecting the specimen Place the patients head on the bed pillow or against a wall so that they do not move backwards The swab will go straight backwards like placing an NG tube, it should go the distance between the nostril and the ear into the throat. This is different from a nasal swab for MRSA or influenza The swab is rotated for a bout 5–10 seconds to get enough epithelial cells on it Remove the swab and place it in the transport media and sent it to lab
Here is a video on specimen collection
Top Mumps Location: Specimen is collected from the parotid duct secretions preferrably within 9 days of symptoms. Swab: Routine cotton swab. Specimen is sent in a viral transport media. Steps Massage the parotid gland for 30 seconds. Note that it is just in front of the ear lobe. Specimen should be collected from the parotid duct opening just next to the second molar.
McHenry County Department of Health (MCDH) has noticed an increase on cases of pertussis in Harvard IL. Please be aware of this vaccine preventable disease when evaluating any child or adult with acute cough like illness characterized by dry hacking cough which may be worse at night associated with paroxysms, a whoop or post tussle gagging or vomiting. Especially if symptoms are lasting greater than 2 weeks.
Please remember to start treatment even before laboratory confirmation
Preferred treatment included – azithromycin, erythromycin or clarithromycin.
Please note the correct way to collect specimen as shown in this video
Pertussis cases should be reported to the county health department using the attached

Collecting a pertussis specimen
We had a bit of confusion of pertussis collection this weekend, so I put together a brief overview on pertussis with focus on nasopharyngeal specimen collection for pertussis.
