Independent predictors of partner HIV testing were discus on HIV (AOR=3.90, 95 %, CI:1.94-7.85), were attend monthly women meeting (AOR=3.3, 95%CI:1.51-5.67), were live not far from 5km (AOR =3.17 ,95%CI:1.41-7.16), were aware availability of PMTCT service (AOR=3.36 95%CI:1.66-6.79), were perceive antenatal clinic give service for both sex (AOR=5.95 ,95%CI:3.07-11.56) and were perceive partner HIV testing is important (AOR=3.32,95%CI:1.45-7.63).
