The NG positive and negative percent agreement were 96.2% (95% CI 86.8%, 99.5%) and 99.8% (95% CI 99.0%, 100%), respectively. Pooled testing identified 4 CT and 1 NG infections that were negative at all anatomic sites by individual testing. Three-site pooled CT and NG testing performs similarly to single anatomic site testing among tests providing a valid result. Future cost analyses should evaluate the cost effectiveness of pooled three-site testing to determine if such a strategy improves the feasibility and accessibility of molecular STI testing.

Chlamydial infection is associated with tubal factor infertility (TFI); however, assessment of prior chlamydial infection and TFI is imperfect. We previously evaluated a combination of serological assays for association with TFI. We now describe the chlamydial contribution to TFI using a newer Chlamydia trachomatis Pgp3 enhanced serological (Pgp3) assay. In our case-control study of women 19-42 years old with hysterosalpingogram-diagnosed TFI (cases) and non-TFI (controls) in two U.S. infertility clinics, we assessed possible associations and effect modifiers between Pgp3 seropositivity and TFI using adjusted odds ratios (aOR) with 95% confidence intervals (CI) stratified by race. We then estimated the adjusted chlamydia population attributable fraction (aPAF) with 95% CI of TFI. All black (n=107) and 618 of 620 non-black women had Pgp3 results. Pgp3 seropositivity was 25.9% (19.3-33.8%) for non-black cases, 15.2% (12.3-18.7%) for non-black cont
