3. Gently remove makeup and ointment with sterile cotton and saline.
4. Collect the specimen using the swab provided in the BD ESwab Collection and Transport System.Pass
swab 2 times over lower conjunctiva. Avoid eyelid border and lashes (culture these separately in a similar fashion, if indicated). Be sure not to touch below the red breakpoint line to avoid contamination.
5. Aseptically unscrew and remove the cap from the tube.
