Reference Interval:
Negative
Interpretive Data: Positive results are confirmed using an alternative nucleic acid target in accordance with CDC guidelines. See: Screening Tests To Detect Chlamydia trachomatis and Neisseria gonorrhoeae Infections - 2002. (http://www.cdc.gov/std/LabGuidelines/rr5115.pdf)

This test is intended for medical purposes only and is not valid for the evaluation of suspected sexual abuse or for other forensic purposes. In certain contexts, culture may be required to meet applicable laws and regulations for diagnosis of C. trachomatis and N. gonorrhoeae infections
