HBsAg Seroconversions [16]

Anti-HCV Seroconversions [72]

In patients newly infected with HBV, HBsAg is the only serologic marker initially detected.

・ 1 - 2 months later: repeat HBsAg testing and test for anti-HBc (including IgM anti-HBc)

・ 6 months later: repeat HBsAg testing and test for anti-HBs

・ If a new HCV infection in a hemodialysis unit is suspected to be nosocomial, testing with NAT should be performed in all patients who may have been exposed.

・ Repeat testing with NAT is suggested within 2 - 12 weeks in initially NAT-negative patients
