Question

A 19-month-old girl underwent a physical examination, and her report showed that although she had received the Hepatitis B vaccine as planned, all three Hepatitis B tests were negative. Additionally, under normal conditions for other indicators, it was found that ‘direct bilirubin levels were very low.’

Answer

Based on the provided information, the child’s liver function test results are normal. Low direct bilirubin levels have no clinical significance and do not require concern. The girl’s five Hepatitis B test results were all negative, indicating that the Hepatitis B vaccine did not produce antibodies in her body, meaning no immune response occurred. It should be continued to administer the Hepatitis B vaccine to the child according to the schedule. In daily life, it is advisable to avoid taking the child to dining establishments with poor sanitation and ensure that food at home is thoroughly cooked before consumption. I hope this answer is helpful to you.
