title: Hepatitis B surface antigen and antibody among Samoans living in Christchurch.
abstract: Ninety-six Western Samoan volunteers were examined for the presence of hepatitis B surface antigen (HBsAg) and antibody (anti-HBs). Seventy-two volunteers were full blooded Samoans and four were found to be asymptomatic carriers of HBsAg. No mixed blood volunteers had detectable HBsAg by either haemagglutination or radioimmunoassay techniques. Fifty of the 72 full blooded Samoans had anti-HBs detectable by radioimmunoassay. Eight of these reactions were only weakly positive. Seventeen of the 24 mixed blood volunteers had detectable anti-Hbs. All were Samoan born. This study suggests that Samoan born Somoans should provide a valuable source of anti-HBs if New Zealand preparation of this antibody is contemplated.
