Reporting of post-transfusion jaundice.
Reports of post-transfusion jaundice were analysed in four successive years from April 1, 1969 to April 1, 1973. Analysis showed a marked reduction in the number of cases reported during the two years of routine HBAg-testing of all blood donations as compared with the two years before this testing was instituted. The value of retrospective studies under present conditions of reporting is discussed.
