A study was conducted at the Louisiana State University School of Dentistry using the radioimmunoassay technique of serum analysis for presence of hepatitis B surface antigen (HBsAg) in all new patients accepted for treatment over a period of one year. The prevalence was 0.61 percent (22 seropositive patients from a total of 3,626 patients screened). Chronic HBsAg carriers, presence of e antigen, and high titers of antibody to hepatitis B core antigen (anti-HBc) were documented. Eighteen of the 22 seropositive patients had no past history of hepatitis, indicating the inadequacy of a history for revealing carriers of HBsAg.
路易斯安那州立大学牙科学院进行了一项研究，运用放射免疫分析技术对一年内接受治疗的所有新患者的血清进行分析，以检测乙型肝炎表面抗原（HBsAg）的存在情况。患病率为0.61%（在总共3626名接受筛查的患者中有22名血清反应阳性患者）。记录了慢性HBsAg携带者、e抗原的存在情况以及高滴度的乙型肝炎核心抗原抗体（抗-HBc）。22名血清反应阳性患者中有18名既往无肝炎病史，这表明仅凭病史不足以发现HBsAg携带者。
