Hepatitis B antibody testing in children?


Hello Dr.
Chen: I was diagnosed with hepatitis B 17 years ago during a blood donation.
Does having hepatitis B mean that I am a carrier? Can it be transmitted to those who share meals with me, or to my spouse or children? Over the past few years, I have been undergoing annual ultrasounds and blood tests, and my AST and ALT levels are all normal! I have mild fatty liver; what else should I pay attention to? A few days ago, there was a news report about a 14-year-old middle school girl who passed away from liver cancer, despite having received the hepatitis B vaccine at birth, because her mother is a hepatitis B carrier and she did not develop antibodies.
The report mentioned that mothers who are hepatitis B carriers should have their children tested for antibodies.
If antibodies are present, the vaccine should be administered again within 10 to 15 years.
I have a 10-year-old daughter and a 6-year-old daughter; should I take them to the hospital for antibody testing? What should I be aware of regarding my daughters? My husband received the hepatitis B vaccine and had antibody testing done 5 years ago, and he has antibodies; what else should he be aware of? I apologize for asking so many questions, and thank you for your help!

Hello, Miss: 1.
Having hepatitis B means you are a carrier.
2.
If you are a carrier, you need to be monitored every six months.
3.
Hepatitis B is transmitted through blood and bodily fluids, not through food or drink.
4.
Children can be tested first, and they can also undergo school health examinations.
5.
If your husband has hepatitis B antibodies, he will not be re-infected.

More Info


Hepatitis B is a viral infection that affects the liver and can lead to serious health issues, including chronic liver disease, cirrhosis, and liver cancer. Understanding the implications of being a Hepatitis B carrier, as well as the necessary precautions for family members, is crucial for managing health and preventing transmission.

Firstly, being diagnosed with Hepatitis B does not automatically mean that you are a chronic carrier. The presence of Hepatitis B surface antigen (HBsAg) in your blood indicates an active infection. If you have been tested positive for HBsAg for more than six months, you are considered a chronic carrier. Regular monitoring through blood tests and ultrasounds is essential to assess liver function and detect any potential complications early.

Regarding transmission, Hepatitis B is primarily spread through blood and bodily fluids. It is not transmitted through casual contact, such as sharing meals or living in the same household. However, it is important to practice safe habits, especially with intimate partners and children. The risk of transmission to family members is low, but it is still advisable to take precautions, such as avoiding sharing personal items like razors or toothbrushes that may come into contact with blood.

In your case, since you have been regularly monitoring your liver function and have mild fatty liver, it is essential to maintain a healthy lifestyle. This includes a balanced diet, regular exercise, and avoiding alcohol, which can exacerbate liver issues. Fatty liver disease, while often manageable, can progress if not addressed through lifestyle changes.

The news story you mentioned about the 14-year-old girl highlights the importance of ensuring that children of Hepatitis B carriers are adequately protected. Since your children are at a higher risk of contracting the virus, it is advisable to have them tested for Hepatitis B surface antibodies (anti-HBs). If they show no immunity, they should receive the Hepatitis B vaccine. The vaccine is highly effective and can provide long-term protection against the virus.

Your husband, having received the vaccine and tested positive for antibodies, is considered protected against Hepatitis B. He should continue to practice general health precautions but does not need to undergo further testing unless there are specific concerns or symptoms.

In summary, here are the key points to consider:
1. Regular Monitoring: Continue your annual blood tests and ultrasounds to monitor liver health.

2. Family Testing: Have your children tested for Hepatitis B antibodies to ensure they are protected. If they lack immunity, vaccination should be pursued.

3. Healthy Lifestyle: Maintain a balanced diet and regular exercise to manage your fatty liver and overall health.

4. Precautions: While the risk of transmission is low, practice safe habits to minimize any potential risk to family members.

By staying informed and proactive about your health and your family's health, you can effectively manage the implications of being a Hepatitis B carrier and ensure the well-being of your loved ones. If you have further questions or concerns, consulting with a healthcare provider specializing in liver diseases can provide personalized guidance and support.
