Anal Cultures

To obtain an anal culture, insert a sterile, cotton-tipped applicator about an inch (2 cm) into the anal canal.

Rotate the cotton-tipped applicator, sampling the anal crypts.

Remove the applicator, and send the specimen in media appropriate for the organism you are seeking:

  • Chocolate agar plates for gonorrhea (or other suitable culture media)
  • Blood agar plates for strep (or other suitable culture media)

If the applicator becomes grossly contaminated with stool, it is better to discard it and obtain another specimen.
