Aj. Winter et al., Comparison of a ligase chain reaction-based assay and cell culture for detection of pharyngeal carriage of Chlamydia trachomatis, J CLIN MICR, 38(9), 2000, pp. 3502-3504
In 264 genitourinary medicine clinic attenders reporting recent fellatio, t
he prevalence of pharyngeal Chlamydia trachomatis determined by an expanded
standard including cell culture and two in-house PCR tests was 1.5% in 194
women and zero in 70 men. The ligase chain reaction (Abbott LCx) had a spe
cificity of 99.2% and a positive predictive value of 60%.
