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 ...

Concomitant Hepatitis B Surface Antigen and Antibody
Annals of Internal Medicine, 1984Excerpt To the editor: Recently, Foutch and associates (1) reported the presence of hepatitis B surface antigen (HBsAg) and its antibody (anti-HBs) in 13 patients.

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 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 ...

Vertical transmission of the hepatitis B surface antigen
The American Journal of the Medical Sciences, 1975Vertical transmission implies transmission of the hepatitis B virus from mother to infant. This occurs with great frequency (70 to 100 per cent) when the mother has acute hepatitis B near delivery. Studies indicate that transmission may occur transplacentally or during the birth process, Once infected, the infants apparently remain hepatitis B surface ...

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 ...

Hepatitis B surface antigen monitoring and management of chronic hepatitis B
Journal of Viral Hepatitis, 2011Summary. Serum hepatitis B surface antigen (HBsAg) levels reflect intrahepatic hepatitis B virus (HBV) covalently closed circular DNA and may be a valuable addition to HBV DNA in the management of patients with chronic hepatitis B (CHB). Among HBeAg‐negative CHB patients with low HBV DNA levels, HBsAg quantification may help distinguish those with ...
