<b>Objective</b> This study aims to determine if transabdominal (TA) cervical length may be used rule out a short cervix on transvaginal (TV) ultrasound. <b>Study Design</b> We conducted prospective cohort of women undergoing routine anatomic survey at 17 23 weeks gestation. TA and TV measurements were obtained in each patient. A was defined as < 30 mm. Predictive characteristics calculated for different cutoff values length. <b>Results</b> There 404 patients enrolled, could not 83 (20.6%) 318 had both measurements. Of those, 14 (4.4%) measurement ≥ 35 mm excluded the possibility (negative predictive value, 99.5%; 95% confidence interval [CI], 97.4; 100%). In our cohort, 67.6% (95% CI, 62.2; 72.7%) ultrasounds have been avoided using <b>Conclusion</b> ATA least excludes While screening feasible 1 5 women, it decrease burden universal screening.
