| Abstract: | The efficency was assessed of the screening for extrahepatic biliary atresia by measuring total bile acids absorbed in dried blood spots at around 5 days of age. When the cut-off level was 54.0 μmol/l, the sensitivity, the specificty and the efficiency of the screening test were 87.9%, 93.9% and 93.9% respectively. The case-finding rate was 0.009% in this type of screening which was three times as many as an early case-finding rate by population screening. These results suggest that teh efficiency of this screening is acceptable. |
