Background: Mycoplasma genitalium (M. genitalium) is an emerging sexually transmitted pathogen of increasing importance. The objective of this study was to compare two tests for the detection of M. genitalium; the Aptima® MG test (Hologic® Inc., San Diego, CA) and the Cobas® TV/MG test (Roche® Diagnostics, Mannheim, Germany).
Methods: This is a prospective descriptive study where a total of 489 genital and extragenital samples were analyzed in parallel and in random order by both systems. The samples were collected from patients attending the Sexually Transmitted Infections Center in Seville and the Infectious Diseases consultation of the Virgen de Valme Hospital.
Results: The overall agreement between both trials was very good (k > 0.91). The sensitivity and specificity of the Aptima® MG test were 100% and 98.7% respectively for the Cobas® TV/MG test.
Conclusion: Both systems showed excellent performance for the detection of M. genitalium.
