Gonococcal infection is diagnosed using which methods?

• A. Nucleic acid amplification tests only
• B. Culture only
• C. Gram stain only
• D. Nucleic acid amplification tests, Gram stain, or culture

Answer: (D)

Gonococcal infection can be diagnosed using multiple approaches because each method has its own strengths depending on the specimen and clinical situation. Nucleic acid amplification tests (NAATs) are highly sensitive and specific and are commonly used on urine or swab specimens from genital sites, as well as from pharyngeal and rectal sites. Culture provides live organisms that allow antibiotic susceptibility testing and confirmation, which is important in settings where resistance patterns need to be tracked or NAATs aren’t available. Gram stain can give rapid, supportive evidence in the right setting—especially in men with acute urethral discharge—by showing Gram-negative intracellular diplococci within neutrophils, but its utility is limited in women and in extragenital infections. Because any of these methods can correctly diagnose the infection depending on the context, the best choice includes all three: NAATs, Gram stain, or culture.
