Are pregnant women tested for Hepatitis B?

Yes. When a pregnant woman comes in for prenatal care, she will be given a series of routine blood tests, including one that checks for the presence of Hepatitis B virus infection. This test is important because women infected with this virus can pass Hepatitis B to their babies during birth. But this can be prevented by giving the infant HBIG and the first Hepatitis B vaccine at birth, and then completing the series.
