Discrepant Hepatitis B Surface Antigen Results in Pregnant Women Screened to Identify Hepatitis B Virus Infection
چکیده انگلیسی

ObjectiveTo resolve discrepant hepatitis B surface antigen (HBsAg) results for pregnant women screened for hepatitis B virus (HBV) infection.Study designA case was defined as discrepant HBsAg (reactive followed by non-reactive) result during the same pregnancy. The Centers for Disease Control and Prevention examined a convenience sample of cases passively reported by US Perinatal Hepatitis B Prevention Programs. Using a standard form, available results were obtained for hepatitis B tests and vaccination histories. Results were independently reviewed by 3 viral hepatitis experts and a clinical virologist to resolve discrepancies. The initial HBsAg result was classified as probable true positive, probable false positive, or unresolved.ResultsFrom April 2009-December 2011, 142 (75.9%) of 187 reported discrepant cases met the case definition. Of the 142 initial reactive HBsAg results, 113 (79.5%) were laboratory-confirmed, and 89 (62.7%) were resolved. Among these 89 cases, the initial test was a probable true positive in 14 (15.7%), and a false positive in 75 (84.3%). Total antibody to hepatitis B core antigen was positive for 11 (78.6%) of the true positive cases and negative for 67 (89.3%) of the false positive cases. True positives included 2 cases of resolving acute HBV infection and one case recently given hepatitis B vaccination.ConclusionsIn this retrospective analysis of discrepant HBsAg-reactive screening results from pregnant women, the majority were false positives, but true positives occurred. Testing for total hepatitis B core antibody, an indicator of past or current HBV infection, was useful for resolving discrepancies.
