[Highly sensitive methods for the serological,diagnosis of hepatitis B and their clinico-epidemiological significance].

A study was made of HB-virus infection markers in 438 patients of different age with hepatitis B. Highly sensitive methods based on the test systems manufactured in this country and abroad were employed. The authors established the diagnostic importance of HBV markers, studied the prevalence of those markers in parents of the diseased children of the first year of life, demonstrated the clinico-epidemiological importance of highly sensitive methods of serological diagnosis.
