Preferred Specimen
Culture material from anterior nares, submitted in Amies' Liquid Transport Medium or Amies' Gel Transport Medium
Other Acceptable Specimens
Culture material from anterior nares, submitted on ESwab
Instructions
1.) Use Amies' Liquid Transport Medium (Red Cap Copan or BD swab, supply #3184), or Amies' Gel Transport Medium (Blue Cap Copan or BD Swab, supply #132749), or ESwab (Copan, supply #15964) to obtain the specimen.
2.) Culture both anterior nares (the opening of each nostril) using one culture swab.
3.) Insert a premoistened swab (use sterile nonbacteriostatic saline or water) about 2 cm and rotate the swab against the nasal mucosa back and forth of each nostril for 3 seconds - slight pressure with a finger on the outside for the nose helps to assure good contact between the swab and the inside of the nose.
4.) Return swab back to the plastic transport tube and make sure the cap is on tight.
Transport to laboratory for testing as soon as possible. Specimens must be received and processed in the laboratory within 48 hours of collection.
Indicate if patient is under antimicrobial therapy. Antimicrobial therapy initiated before the collection of specimens may result in a false negative culture.
