What does ACOG say about screening strategies for preterm labor?
ACOG points out that there are no current data to support the use of salivary estriol tests, home uterine activity monitoring, or bacterial vaginosis screening strategies to identify the risk of or prevent preterm birth. Widespread screening for risk of preterm labor is not beneficial in the general obstetric population. Ultrasonography to determine the cervical length and/or fetal fibronectin screening may be useful in determining who is at high risk for preterm labor, but the benefit may be mainly to rule out those who are not at high risk for preterm birth.
