Does 1 year old baby need to check hepatitis B antibody during physical examination

One year old babies usually need to check hepatitis B antibody for physical examination.

hepatitis B antibody test is an important means to evaluate the vaccination effect. In China, hepatitis B vaccine has been included in the national immunization plan, and newborns need to be vaccinated three times according to the 0-1-6 month procedure after birth. Antibody testing around the age of 1 can confirm the production of effective protective antibodies. If the surface antibody level reaches 10mIU/ml or above, it indicates successful immunization; If the value is lower than this, it may require vaccination. The examination process only requires the collection of a small amount of venous blood, which will not cause significant discomfort to infants and young children. It is recommended that parents make an appointment with the community health service center in advance and choose a time when their baby's mental state is better for examination. It is not necessary to fast before the examination, but testing should be avoided during periods of fever or acute illness.

In addition to hepatitis B antibody detection, the physical examination at the age of 1 should also focus on growth and development assessment, blood routine test, vision screening and other items. In daily life, it is necessary to keep the vaccination site clean and dry, and observe for any adverse reactions such as redness, swelling, heat, and pain. If the antibody test results are abnormal, it is necessary to consult a preventive healthcare doctor in a timely manner and decide whether to strengthen immunity based on the specific situation. At the same time, pay attention to avoid sharing tableware, toothbrushes and other items that may contact blood with hepatitis B virus carriers, and take family protection measures.
