Addressing Neisseria gonorrhoeae Treatment Resistance With the DNA Gyrase A Assay: An Economic Study, United States.

Targeted antibiotics could delay emergence of resistant Neisseria gonorrhoeae. The DNA gyrase subunit A assay predicts susceptibility to ciprofloxacin. A model found that adding a $50 gyrase subunit A test for asymptomatic patients screened for N. gonorrhoeae resulted in cost neutrality. When ciprofloxacin susceptibility was high, a $114 test resulted in savings.
