Abstract
The method of radial immunodiffusion for measurement of hepatitis B antigen (HB ag) levels in sera of twenty and urines of three HB ag positive patients is described. In patients suffering from acute hepatitis, the level of HB ag in serum was 0·15–2·12 mg/ml (mean = 1·08±SD 0·69 mg/ml). In patients suffering from chronic hepatitis the level of HB ag in serum was 0·36–3·61 mg/ml (mean 2·56±SD 1·13 mg/ml). The highest levels of HB ag in serum, 2·62–5·12 mg/ml (mean 3·91±SD 0·90 mg/ml) were observed in symptomless HB ag carriers.
The amounts of HB ag excreted in urine, found in two chronic hepatitis patients and one HB ag carrier, were 13·2 mg, 46 mg and 82 mg/1000 ml of urine respectively.
