Specimen Requirements

PCR is a very sensitive test and precaustions should be taken to not cross-contaminate specimens.

Buccal swab: Swab the buccal cavity (the space between the cheek and teeth).  The parotid duct drains in this space near the upper molars.  Massage the parotid gland area just in front of the ear and near the angle of the jaw for about 30 seconds prior to collecting secretions on the swab.  Swab the area between the cheek and gum by sweeping the swab near the upper molar to the lower molar area. 

Place swab in universal viral transport medium (UTM) and do not remove swab.  Transport media is available from the lab.

Refrigerate (2 - 8 C).  DO NOT FREEZE.

Note: Indicate specimen source on specimen container and in computer.
