Introduction
If a male with chronic hepatitis B has stable condition, normal liver function, low viral load, and no signs of liver inflammation or fibrosis, he can safely plan for pregnancy and have a healthy baby. By ensuring his partner receives the hepatitis B vaccine in advance and confirms the development of protective antibodies, transmission of the virus through daily contact can be effectively prevented, thereby reducing the risk of fetal infection.

Generally, if a male with hepatitis B "big three positives" has stable condition and takes proper protective measures, he can father a healthy baby. However, if the disease is in an active phase, it is recommended to postpone conception. If there are any concerns, it is advisable to consult a doctor in advance. The detailed analysis is as follows:

If the male with hepatitis B "big three positives" has a stable condition, normal liver function, low viral load, and no signs of liver inflammation or fibrosis, it is possible to effectively prevent transmission of the virus to his partner through daily contact by ensuring the partner receives the hepatitis B vaccine in advance and develops protective antibodies. This significantly reduces the risk of fetal infection, allowing for normal pregnancy planning and the birth of a healthy baby.

If the male's hepatitis B is in an active phase, characterized by abnormal liver function, persistently high viral load, and no protective measures taken, the increased viral activity may raise the likelihood of infecting the partner, thereby indirectly increasing the risk of fetal infection. Additionally, the man’s own condition could worsen due to increased physical stress. In such cases, immediate conception is not recommended; treatment should first be undertaken to control the disease.

Prior to conception, men with hepatitis B "big three positives" should undergo comprehensive liver function and viral load testing, and ensure their partners complete the hepatitis B vaccination series. During pregnancy, they should avoid excessive fatigue, have regular follow-up examinations, and strictly follow medical advice to safeguard the health of both mother and baby.

Does the company health checkup include hepatitis B testing?
Whether a routine health checkup at the workplace includes hepatitis B testing depends on the specific circumstances. Standard pre-employment physicals usually do not include hepatitis B screening. Typical pre-employment examination items generally cover basic health indicators such as blood tests, urine tests, and electrocardiograms, aimed at assessing an employee's overall health status. Hepatitis B testing is typically excluded from these routine checks in order to protect personal privacy and prevent employment discrimination.

What virus is HBsAg?
HBsAg is a viral marker produced after hepatitis B virus infection. It is not the virus itself, but rather a protein component found on the outer surface of the hepatitis B virus. In daily life, it is important to protect liver health by maintaining regular作息 (daily routines), avoiding excessive fatigue, and allowing sufficient time for liver cell repair. A light and balanced diet is recommended, with reduced intake of high-fat, high-sugar, and irritating foods to lessen the metabolic burden on the liver.

When should the third dose of the vaccine be administered, after how many months?
In general, the timing for the third dose of a vaccine varies depending on the vaccine type. For COVID-19 vaccines, the third dose is typically administered 6 months after completing the second dose. Other vaccines, such as hepatitis B and HPV vaccines, follow fixed schedules, so the specific vaccine type must be considered to determine the appropriate interval. Before vaccination, individuals can check the vaccine type and recommended intervals through vaccination sites or official channels, and complete the vaccination on schedule.

What does a five-item blood liver function test check for?
The five-item liver function blood test generally includes examination of hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B e-antigen, hepatitis B e-antibody, and hepatitis B core antibody. Hepatitis B surface antigen is a protein from the outer shell of the hepatitis B virus. Although it is not infectious by itself, its presence usually indicates the existence of the hepatitis B virus and serves as a marker for hepatitis B infection. A positive result suggests possible hepatitis B infection.

What Chinese herbs can completely cure "small three positives" (HBeAb, HBsAb, and HBcAb positive in hepatitis B)?
There is currently no traditional Chinese medicine that can completely cure "minor three positives" (a pattern of hepatitis B virus markers), but certain herbal medicines may help alleviate symptoms and regulate the immune system. Commonly used medications include Hugan Pian, Anluo Huaxian Wan, Yexiazhu Capsules, and Yinchenhao Tang. Hugan Pian contains ingredients such as Bupleurum and Artemisia capillaris (Yinchen), which help soothe the liver, regulate qi flow, and reduce transaminase levels. It is suitable for patients with "minor three positives" who have mild liver function abnormalities, and can improve symptoms such as distension and pain in the hypochondriac region and reduced appetite.

Its main symptoms include fatigue, poor appetite, jaundice, dull pain in the liver area, nausea and vomiting, and darkened urine. Hepatitis D frequently occurs as a simultaneous or superimposed infection with hepatitis B, and its symptoms are easily masked by those of hepatitis B. Individuals with a history of hepatitis B should undergo regular check-ups and take appropriate measures to protect their liver.

What does it mean if a pregnant woman has high levels of hepatitis B core antibody?
Elevated hepatitis B core antibody levels in pregnant women may result from previous hepatitis B virus infection, testing errors, immune fluctuations during pregnancy, chronic hepatitis B, or acute phase of hepatitis B virus infection. This condition can be confirmed through retesting and improved by lifestyle adjustments or medication. If accompanied by abnormal liver function, fatigue, or other symptoms, prompt medical attention is necessary.
