Gonorrhea Test of Cure: Timing and Method

When to Perform Test of Cure

A test of cure for gonorrhea should be performed 1 week after treatment if alternative regimens are used, with culture being the preferred method when available, or NAAT if culture is not available, as recommended by the Centers for Disease Control and Prevention 1, 2, 3, 4
Routine test of cure is NOT recommended for patients who receive the standard recommended treatment for uncomplicated urogenital or rectal gonorrhea, according to the Centers for Disease Control and Prevention 1
Test of cure IS recommended for patients treated with alternative regimens, patients with pharyngeal gonorrhea, patients with persistent symptoms after treatment, and cases of suspected treatment failure, as stated by the Centers for Disease Control and Prevention 1, 2, 3, 4, 6

Culture is the ideal method for test of cure as it allows for antimicrobial susceptibility testing, is essential in cases of suspected treatment failure, and should be performed at the infected anatomic site, as recommended by the Centers for Disease Control and Prevention 1, 3, 6, 7, 8
If culture is not available, NAAT can be used, but it may detect residual DNA/RNA from dead organisms, potentially leading to false positives if performed too early, according to the Centers for Disease Control and Prevention 6, 8

For suspected treatment failures, obtain specimen for culture and antimicrobial susceptibility testing, report the case to local public health officials within 24 hours, consult an infectious disease specialist, and consider alternative treatment regimens based on susceptibility results, as recommended by the Centers for Disease Control and Prevention and the Lancet Infectious Diseases 1, 6
A positive NAAT result 2-3 weeks after treatment, in the absence of re-exposure, is indicative of treatment failure, according to the Lancet Infectious Diseases 6

All sex partners from the preceding 60 days should be evaluated and treated, and patients should avoid sexual intercourse until therapy is completed and both they and their partners are asymptomatic, as recommended by the Centers for Disease Control and Prevention 1, 5
If partners' treatment cannot be ensured, consider expedited partner therapy, according to the Centers for Disease Control and Prevention 1, 5

Failing to obtain culture in treatment failure cases is a common pitfall, as culture is essential for antimicrobial susceptibility testing, as stated by the Centers for Disease Control and Prevention and the Lancet Infectious Diseases 1, 6, 7
Not considering pharyngeal infections and not addressing partner treatment are also common pitfalls, as pharyngeal infections are more difficult to eradicate and untreated partners are a common source of reinfection, according to the Centers for Disease Control and Prevention and Praxis Medical Insights 1, 5
