The Detection of Hepatitis B Surface Antigen by Radioimmunoassay
Pathology, 1975A comparative study was performed to assess the sensitivity and specificity of counterimmunoelectrophoresis (CIEP) and radioimmunoassay (RIA) for the detection of hepatitis B surface antigen. The 8,823 sera examined included selected reference panels and sera collected from populations with low, moderate and high rates of chronic antigen carriage ...

Thermal Inactivation of Hepatitis B Surface Antigen
The Journal of Immunology, 1978Abstract Thermal inactivation of hepatitis B surface antigen (HBs Ag) was investigated under various experimental conditions by means of a quantitative radioimmunoassay. No decrease of HBs Ag immunologic reactivity could be detected at -80°C, up to 24 months of storage, whereas at -20 and 4°C survival of serum HBs Ag after 6 months was ...

The incidence of hepatitis B surface antigen in Nigeria
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1979We have determined the incidence of hepatitis B surface antigen (HBsAg) in an urban (Enugu) and a rural (Okpatu) population groups in Nigeria. There were no statistically significant differences between the incidence in the two populations. Contrary to earlier reports we did not observe any significant age-related differences in the incidence rates ...

Hepatitis B surface antigen in the Iraqi population
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1976Using counter immunoelectrophoresis (CIEP), the carrier rate of HBsAg among the Arab Population of Iraq was found to be 2.8% comparted with 5.5% in the Kurd population. The incidence of antigenaemia in laboratory workers, renal dialysis staff and patients, nursing and blood bank staff, and pulmonary tuberculosis and diabetes mellitus patients is also ...

A New Hepatitis B Virus Surface Antigen
Journal of Infectious Diseases, 1976A new determinant of hepatitis B surface antigen (HBs Ag), g, which is distinct from the previously identified determinants a, d, y, w, and r, was studied. This new antigen tended to be associated with the d antigen; it was found in 97% of ad specimens and in 15% of ay specimens.

Hepatitis B Surface Antigen in Human Tears
Archives of Ophthalmology, 1978The incidence of hepatitis B virus infection has been increasing every year in the United States, particularly among medical personnel. Only half of these cases are associated with exposure to blood or blood products. Respiratory, fecal-oral, and venereal methods of transmission of hepatitis B virus infection are supported by epidemiological evidence ...

Origin of salivary hepatitis B surface antigen
European Journal of Oral Sciences, 1980Abstract –Low titers of hepatitis B surface antigen (HBsAg) is often found in mixed saliva of antigenemic individuals. In the present study the occurrence of antigen in saliva was correlated to the content of albumin, which is not synthesized by the salivary glands, but represents a leakage into the oral cavity due to hemorrhage, exudation or ...

Subtyping of hepatitis B surface antigen by radioimmunoassay
Journal of Immunological Methods, 1979Abstract A solid-phase radioimmunoassay used for HBsAg screening of blood donors at the Finnish Red Cross Blood Transfusion Service (FRC-RIA) was modified for subtyping of HBsAg. The anti-HBs coated test tubes of FRC-RIA served as the solid-phase anti-HBs.
