Why Is My HBsAg Reactive, But Core Antibody Non-reactive, Surface Antibody High, And PCR Undetected During Pregnancy?

Hi, I am pregnant and recently tested reactive for HBSaG, but I was vaccinated. My Hept B core antibody is non-reactive, surface antibody from vaccination is 700, and my viral PCR test was not detected. No idea what test to ask for next because this doesn t make sense.
