[Detection of antibodies and assessment of an international unit of anti-HBs specific immunoglobulin, HEPAGA].
The authors submit information on the presence and titre of antibodies against antigens of the hepatitis B virus [HB] and the Czechoslovak specific anti-HBs immunoglobulin, HEPAGA, and on the presence of the delta-antibody. The presence of the antibody against the surface antigen of the HB virus [HBsAb, anti-HBs] was examined in 32 batches, the antibody against the nucleus of the HB virus [HBcAb] and e-antigen [HBeAb] in a total of 27 batches. HBsAb was positive in the majority of cases still when diluted 1/2,500,000; HBcAb when diluted in the range from 1/25,000 to 1/2,500,000; the positivity of HBcAb ended with the exception of one batch at the dilution of 1/250. The delta antibody was detected only in batches from 1982 and 1983, in a maximum dilution of 1/8. All examinations were made by the radioimmunoassay [RIA] technique. The authors give also an account of the assessment of the international HEPAGA [IU/ml]. The last batch has 170 IU/ml.
