Abstract
OBJECTIVE: The prevalence of Mycoplasma hominis and Ureaplasma urealyticum (genital mycoplasma) amongst Indonesian women is poorly understood because of limited availability of diagnostic techniques. We sought to compare the diagnostic parameters of the AF Genital System® with those of culture methods and PCR as the gold standard for identification of M. hominis and U. urealyticum in vaginal swab specimens. METHODS: This was an observational diagnostic study. Eighty-eight specimens were collected from patients with abnormal vaginal discharge. Detection of M. hominis and U. urealyticum was performed using the AF Genital System®, culture methods, and PCR. RESULTS: Compared with PCR and culture methods, respectively, the AF Genital System® had sensitivities of 66.6% and 57% (M. hominis) and 55.5% and 77.8% (U. urealyticum). Compared with PCR and culture methods, respectively, the AF Genital System® had specificities of 82.9% and 86.5% (M. hominis) and 82.3% and 84.8% (U. urealyticum). CONCLUSION: The sensitivity of the AF Genital System® for detection of M. hominis and U. urealyticum from vaginal swab samples was lower than that of PCR, but specificity was reasonably good (82% to 83%).
