Introduction

A positive HBsAg in the mother indicates the presence of hepatitis B surface antigen, suggesting she may be a carrier of the hepatitis B virus or currently infected with hepatitis B. For pregnant women who are HBsAg-positive, appropriate preventive measures can reduce the risk of transmitting the hepatitis B virus to the newborn. It is recommended to develop an individualized treatment plan and preventive strategies based on specific circumstances.

Generally, a positive HBsAg result in a mother indicates the presence of hepatitis B surface antigen in her body, suggesting that she may be a carrier of the hepatitis B virus or currently experiencing a hepatitis B infection. The details are as follows:

If the mother is a carrier of the hepatitis B virus, the virus persists in her body and she may transmit it to others, including her newborn. This means there is a risk of hepatitis B transmission during childbirth, as the virus can be passed to the newborn through blood, bodily fluids, or vertical (mother-to-child) transmission.

For pregnant women who are HBsAg-positive, appropriate preventive measures can significantly reduce the risk of transmitting hepatitis B to the newborn. It is recommended to consult healthcare professionals to develop an individualized treatment plan and prevention strategy based on specific circumstances.

Can HBsAg positive and HBeAb positive (HBV 45 positive) resolve spontaneously?

Hepatitis B refers to hepatitis type B. If the condition of hepatitis B is mild and there are only four positive markers (commonly referred to as "45 positive"), the so-called "big three" or "small three" positive patterns may not necessarily develop, and the disease can usually be cured. However, once these patterns have developed, spontaneous recovery is unlikely. In daily life, it's important to ensure adequate sleep, avoid prolonged late-night hours, maintain regular作息 (daily routines), and avoid processed foods in the diet.

Is a physical examination considered合格 (qualified) if the result for hepatitis B is positive for both items 2 and 4?

A positive result for items 2 and 4 in a hepatitis B test indicates possible carriage of the hepatitis B virus. Whether such individuals pass a medical examination depends on the specific job requirements. As long as liver function is normal, individuals can undergo medical screening as hepatitis B carriers. Hepatitis B carriers should have regular liver function tests, and if abnormalities in liver function are detected, timely treatment is necessary.

Is "Big Three Positive" of hepatitis B a type of hepatitis?

The term "Big Three Positive" for hepatitis B refers to a positive result for hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg), and hepatitis B core antibody (anti-HBc) in the five-item hepatitis B test. This indicates active replication of the hepatitis B virus in the body and a relatively high level of infectivity. Patients typically have liver inflammation, as the extensive replication of the virus stimulates the immune system. During the process of clearing the virus, the immune response can damage liver cells, leading to an inflammatory reaction.
