Comments

This test is offered ONLY to the Emergency Department,Urgent Care and select Laboratory Service Centers locations for patients who will be managed as outpatients. OUTPATIENT specimen must be transported to one of the following Laboratory Service Centers or Nationwide Children’s Close to Home Centers with laboratory services (Canal Winchester, Dublin, East Broad, Hilliard, Marysville, Newark, Springfield, Westerville, and Washington Court House) by the parent or legal guardian, within 1 hour of collection. For patients to be admitted to the hospital, consider ordering test FARVPP (Respiratory Infection Array; performed once per day, 7 days a week) which has higher sensitivity. A posterior nasopharyngeal swab collection submitted in the swab transport tube is the preferred collection method. Sofia RSV testing is not recommended for patients GREATER than 7 years of age, as test sensitivity is low for this population. Results should be interpreted with caution.
