Half life of transfused anti-HBs.

Developments in biological standardization, 1976
During a prospective study in post transfusion hepatitis 222 blood units were given to 55 patients who underwent open heart surgery. Eleven of these blood units contained anti-HBs titered higher than 1:128 by passive hemagglutination and were given to 10 patients previously negative for anti-HBs.

Detection and quantification of anti-HBs antibodies by the Czechoslovak ELISA SEVAC Kit (Sevatest ELISA anti-HBs).

Journal of hygiene, epidemiology, microbiology, and immunology, 1988
We invented and verified the possibilities of clinical use of the ELISA Kit for quantification of human serum anti-HBs antibodies. The kit does not employ any labelled antigen but is based on the principle of neutralization. The kit was tested on the panel of sera of the normal population, blood donors, workers at risk workplaces and persons vaccinated

[Improvement of quantitative method on anti-HBs].

Zhonghua shi yan he lin chuang bing du xue za zhi = Zhonghua shiyan he linchuang bingduxue zazhi = Chinese journal of experimental and clinical virology, 2010
Through detecting the standard preparation with series of concentration to indirectly calculate the anti-HBs concentration of the serum samples, a suitable anti-HBs quantitative method for our laboratory was found after comparing the two kinds of methods.Detecting the anti-HBs standard preparation with series of concentration by RIA method, standard ...

Experiences with radioimmunoassay in the detection of HBsAg in the presence of anti‐HBs

Journal of Medical Virology, 1978
AbstractInterference from anti‐HBs present during hepatitis B antigenemia caused the appearance of several false negative reactions in a competition radioimmuno‐precipitation procedure. The results indicate that such interference is considerably less in the solid‐phase radioimmunoassay (Ausria II) and probably causes few false negative tests.

Affinity of anti‐HBs antibody after hepatitis B vaccination

European Journal of Clinical Investigation, 1992
Abstract. A novel method based on mathematical analysis of the dose‐response curve obtained by radioimmunoassay was used to determine anti‐HBs affinity and concentration in 29 healthy subjects vaccinated with plasma‐derived hepatitis B vaccine. Anti‐HBs affinity as well as its serum concentration increased with time in most vaccine recipients; however,

Prevalence of HBsAg and anti HBs in hospital personnel.

Journal of hygiene, epidemiology, microbiology, and immunology, 1979
Of the 473 employees of a Prague hospital, examined for the presence of hepatitis B surface antigen (HBsAg) and the antibody to it (anti HBs), 23 (4.9%) were shown to have the antigen and 88 (18.6%) to have the antibody. No differences were found in the prevalence of HBsAg and anti HB according to sex and age, but the percentage of persons with ...

Distribution of anti HBs in Christchurch hospital staff.

The New Zealand medical journal, 1978
Three hundred and thirty-eight North Canterbury Hospital Board staff in 11 different job categories have been tested for anti HBs during a two-year period, June 1975 to June 1977. Forty-three sera were positive for anti HBs, 10 following documented hepatitis B, nine following prophylactic anti HBs and 23 without any previous history of hepatitis.

[Prevalence of HBsAg and anti-HBs in hospital personnel].

Bollettino dell'Istituto sieroterapico milanese, 1982
The prevalence of serum HBsAg and Anti-HBs was studied in 201 staff members from two Renal Dialysis Units, one Medical and one Dermatological Division from two Hospitals in the Milano area. The overall prevalence of HBsAg was significantly greater among staff members (8.9%) as compared to controls (4.9%). On the contrary, the prevalence of Anti-HBs was
