Introduction

Hepatitis B virus antibody, also known as hepatitis B surface antibody, normally measures 0 mIU/mL in individuals who have not received the hepatitis B vaccine. For those who have been vaccinated, a normal level is above 10 mIU/mL. Over time, the antibody titer produced by the body gradually decreases, and when it falls below 10 mIU/mL, revaccination with the hepatitis B vaccine is required.

　　Hepatitis B virus antibody, also known as hepatitis B surface antibody, normally measures 0 mIU/mL in individuals who have not received the hepatitis B vaccine. For those who have been vaccinated against hepatitis B, a normal level is considered to be above 10 mIU/mL.

　　In healthy individuals who have neither been infected with the hepatitis B virus nor vaccinated, the normal level of hepatitis B surface antibody is 0 mIU/mL. This indicates no immunity against the virus, making them susceptible to infection upon exposure. It is recommended that such individuals receive the hepatitis B vaccine promptly to prevent infection and potential liver diseases.

　　For individuals who have received the hepatitis B vaccine, a normal level of hepatitis B surface antibody is above 10 mIU/mL, indicating adequate immunity. Over time, antibody levels may gradually decline. If the level drops below 10 mIU/mL, revaccination is recommended.

　　It is important to maintain liver health and take preventive measures. If hepatitis B infection occurs, prompt medical treatment is necessary.

Can hepatitis B virus cause fetal malformations?

The hepatitis B virus itself usually does not directly cause fetal malformations; its primary risk is transmitting the virus to the fetus. To reduce the risk of mother-to-child transmission, pregnant women who are hepatitis B surface antigen positive should receive antiviral interventions under medical guidance, including appropriate use of antiviral medications during pregnancy and timely administration of hepatitis B immunoglobulin and the first dose of hepatitis B vaccine to the newborn after birth.

Are hepatitis B surface antigen (HBsAg) and hepatitis B core antibody (anti-HBc) positive results infectious?

HBsAg negative, anti-HBs positive, HBeAg negative, anti-HBe negative, and anti-HBc positive (i.e., positive for the second and fifth markers) usually indicates no infectivity. This result suggests a past hepatitis B virus infection that has resolved, with development of immunity against hepatitis B. Individuals with positivity only for the second and fifth markers do not need to worry about transmitting the virus and require no special treatment. It is recommended to periodically check the titer of hepatitis B surface antibody; if the titer drops below the protective level, appropriate measures such as booster vaccination may be considered.

Can hepatitis B be transmitted through sweat?

Under normal circumstances, sweat cannot transmit hepatitis B, and there is currently no scientific evidence that the hepatitis B virus can be transmitted through sweat. Therefore, there is no need to worry about contracting hepatitis B through sweat; everyday contact such as handshakes or sharing office supplies does not spread the hepatitis B virus. An effective way to prevent hepatitis B is vaccination. High-risk individuals should also avoid sharing needles.

Can patients with hepatitis B take entecavir?

In general, "hepatitis B" refers to hepatitis B virus infection. Patients with chronic hepatitis B can take entecavir, which is a first-line antiviral drug in clinical treatment. Entecavir can effectively suppress hepatitis B virus replication and delay the progression of liver damage. However, it must be used properly under the guidance of a doctor; self-medication or stopping the medication without medical advice is not recommended. During treatment, patients should regularly undergo follow-up tests for liver function and viral markers.

Can hepatitis B be cured?

In general, hepatitis B refers to Hepatitis B virus (HBV) infection. Whether it can be cured depends on the specific situation. Most cases of acute hepatitis B can be completely cured, while chronic hepatitis B is currently difficult to eradicate entirely. However, with proper treatment, the condition can be effectively controlled over the long term, allowing patients to maintain a normal life. The key difference lies in the age at which the virus is acquired and the type of disease presentation. If you suspect or have been diagnosed with hepatitis B, it is recommended to seek timely medical care at a正规 hospital.

Is it necessary to get a hepatitis B booster shot?

In general, whether a hepatitis B booster shot is necessary depends on the status of hepatitis B surface antibodies in the body. If the hepatitis B surface antibody is positive and the titer is sufficient, vaccination is usually not required. However, if the hepatitis B surface antibody is negative, or if the antibody is positive but the titer is insufficient, vaccination is recommended. To maintain liver health and reduce the risk of hepatitis B virus infection, it is advised to undergo regular hepatitis B antibody testing.

What is the difference between "big three positive" and "small three positive" in hepatitis B?

Under normal circumstances, the main differences between hepatitis B "big three positives" and "small three positives" include different viral markers, varying levels of viral replication activity, differing degrees of infectivity, different risks of liver damage, and distinct treatment strategies. In addition, patients with either hepatitis B "big three positives" or "small three positives" should undergo regular liver function tests and hepatitis B virus DNA testing.

Which of the Five Hepatitis B Antigen-Antibody Tests Being Positive Is Considered Normal?

When all five hepatitis B tests are negative, it indicates that the body has not been infected with the hepatitis B virus (HBV) and has not developed protective antibodies. This is considered a healthy state; however, it also means there is no immunity against HBV. It is recommended to receive the hepatitis B vaccine promptly to gain protection and reduce the risk of infection. If only the surface antibody is positive, it usually indicates prior vaccination or recovery from a past HBV infection.
