ABSTRACT
BACKGROUND:
Many molecular diagnostic methods have been developed to detect sexually transmitted infections (STI). The STDetect Chip (LabGenomics, Korea) which is a DNA microarray-based tool, newly developed for STI diagnosis in vitro, and the real-time PCR-based Anyplex STI-7 (Seegene, Korea) in clinical use were evaluated using ATCC DNA and clinical samples to determine the clinical usefulness of the STDetect Chip.METHODS:
The two methods were compared for consistency, sensitivity, and specificity for 6 pathogens in 300 prospectively selected clinical samples. Analytical sensitivity for ATCC Neisseria gonorrhoeae, Chlamydia trachomatis, Mycoplasma hominis and Trichomonas vaginalis DNA and the effect of mixing bacterial DNA were studied.RESULTS:
The consistency of the two methods for clinical samples was superior at more than 0.92 kappa value. The sensitivity and specificity of the STDetect Chip compared with Anyplex STI-7 were 90.5-98.8%, and 95.6-99.6%, respectively. With similar analytical performance for ATCC DNA, the STDetect Chip detected 10(-5) ng/µL of N. gonorrhoeae, 10(-4) ng/µL of C. trachomatis, 10(-6) ng/µL of M. hominis, and 10(-3) ng/µL of T. vaginalis. For the mixture of three bacterial DNAs, less sensitive detection level was observed for T. vaginalis.CONCLUSIONS:
The STDetect Chip showed good agreement with the Anyplex STI-7 test and it is considered clinically useful for detecting sexually transmitted pathogens.
