A 30-year-old woman presented with 3 days H/O mucopurulent cervical discharge. On gram stain of the discharge, numerous pus cells were seen but no organism was seen. Investigation of choice for diagnosis of this infection?
Correct Answer: Nucleic acid amplification test
Description: Based on the clinical history, the most likely diagnosis is acute cervicitis and as gram stain does not show any organism (so gonococcal infection is less likely); hence, Chlamydia trachomatis is the most likely organism. For C. trachomatis, investigation of choice and the most sensitive investigation is nucleic acid amplification test (NAAT).
