Clinical Utility


Test Specimen

  • Throat or nasopharyngeal swab in 3 mL V-T-M medium or Universal transport media equivalent

  • Specimen should be collected during acute phase of the disease, ideally within 24 hours of onset of symptoms. Guide the flexible (ideally a flocked rather than wound) swab into the contour of the nares and into the nasopharynx. Leave in place 15 to 30 seconds, rotate and remove. Place swab in viral transport.

  • Throat swab: Carefully rub the posterior nasopharynx with a dry sterile swab (preferably the "flocked swab"). Avoid touching the tongue or buccal mucosa. Place swab in viral transport.
