Pregnant women who are at low risk of preterm delivery and exhibit no symptoms of vaginal infection should not be screened for vaginosis,
according to an updated recommendation from the US Preventive Services Task Force (USPSTF).
This update to the 2001 USPSTF recommendations was based on review of the literature and was published in February (US Preventive Services Task Force. Ann Intern Med. 2008;148:214-219).
The review assessed the evidence supporting vaginosis screening in both women who are at low risk of preterm delivery and those at high risk. However, because the task force found insufficient evidence addressing the benefits and risks of screening women who had an elevated risk of delivering early, no recommendation was made for such women.
