Special Instructions and Considerations:  

Swab Specimens: Remove any excess mucus using the cleaning swab (white shaft swab in the package with red printing). Discard this swab. The specimen collection swab (blue shaft swab in the package with the green printing) should be placed into the transport tube immediately after collection.

Excessive lubricant may interfere with sample adequacy.  Must be processed within 30 days of collection.

Causes for Rejection: Improperly labeled or expired vial, frozen specimen, Aptima Unisex tube containing anything other than the blue swab, or specimen older than 21 days from collection.

Limitations, Causes for Unsatisfactory Results:  Sample collected near menstrual cycle or with excessive lubricant
