Introduction
Under normal circumstances, a positive result for hepatitis B usually refers to a positive hepatitis B surface antigen (HBsAg). A positive HBsAg may be caused by hepatitis B vaccination, recovery phase after natural infection, acute viral hepatitis B, chronic hepatitis B, hepatitis B cirrhosis, or other related conditions. It is generally advisable to maintain a balance between work and rest, avoiding excessive fatigue that may lead to a decrease in immune function.

Generally, a positive result for hepatitis B refers to a positive test for hepatitis B surface antigen (HBsAg). A positive HBsAg result may be caused by hepatitis B vaccination, recovery phase after natural infection, acute viral hepatitis B, chronic hepatitis B, hepatitis B-related cirrhosis, and other conditions. If you experience any discomfort, please seek medical attention promptly. Detailed explanations are as follows:

1. Hepatitis B Vaccination

After receiving the hepatitis B vaccine, the body produces hepatitis B surface antibodies, which can lead to a positive test result. No special treatment is required. Regular monitoring of antibody levels is recommended, with booster immunizations if necessary.

2. Recovery Phase After Natural Infection

Following infection with the hepatitis B virus, some individuals may clear the virus and enter the recovery phase. During this time, hepatitis B core antibodies can be detected, resulting in a positive test result. It is important to ensure adequate rest, maintain a balanced diet, avoid alcohol and substances toxic to the liver, and monitor changes in liver function.

3. Acute Viral Hepatitis B

The hepatitis B virus rapidly invades the body, causing hepatitis B infection, which leads to acute viral hepatitis B. The virus replicates in the body, causing the aforementioned symptoms, including vomiting and yellow urine. Follow medical advice to take medications such as acyclovir tablets, famciclovir tablets, acyclovir cream, and others for treatment.

4. Chronic Hepatitis B

Chronic hepatitis B is mainly caused by genetic factors, low immunity, and other reasons. If acute viral hepatitis B does not fully resolve, the virus may continue to replicate in the body, causing repeated liver damage and a positive test result. Symptoms such as pain in the liver area and jaundice may appear. Under the guidance of a specialist, medications such as compound glycyrrhizin tablets, glucurolactone tablets, entecavir dispersible tablets, and others may be used for treatment.

5. Hepatitis B Cirrhosis

Hepatitis B cirrhosis represents the advanced stage of chronic hepatitis B. When the hepatitis B virus persists in the body for more than six months, it causes chronic inflammation and fibrosis of the liver, leading to the aforementioned symptoms, which may be accompanied by ascites and splenomegaly. It is recommended to follow medical instructions to use medications such as hepatocyte growth-promoting factor for injection, diammonium glycyrrhizinate capsules, and Fuzheng Huayu capsules for treatment.

In daily life, it is important to balance work and rest, avoiding excessive fatigue that may weaken immune function. Additionally, avoid high-risk behaviors, such as using unsterilized needles and sharing personal items with individuals who have viral hepatitis B.

What should you eat if you have mild hepatitis B (small three positives)?
In general, patients with "small three positives" (chronic hepatitis B with positive HBsAg, anti-HBe, and HBV DNA) should support liver health through diet while using medication to control the condition. Recommended foods typically include eggs, broccoli, sea bass, spinach, and oats. Commonly used medications include entecavir dispersible tablets, tenofovir disoproxil fumarate tablets, silybin capsules, compound glycyrrhizin tablets, and hepatoprotective tablets.

How long can the second dose of the hepatitis B vaccine be postponed?
If the vaccination is postponed due to short-term unexpected situations such as a mild cold or temporary travel, it is sufficient to receive the missed dose within one month; there is no need to restart the entire vaccination series. The subsequent third dose should still be administered according to the originally planned interval and will generally result in normal production of effective antibodies. However, if the delay exceeds one month, especially beyond two months, the immune memory induced by the first vaccine dose may weaken.

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.

How to determine normal results for the five hepatitis B tests
Under normal circumstances, the main results of the five hepatitis B tests include all negative, only hepatitis B surface antibody positive, and hepatitis B surface antigen negative with hepatitis B surface antibody positive. Additionally, determining whether the five hepatitis B test results are normal requires a comprehensive analysis of all indicators; a single result should not be viewed in isolation. If there are doubts about the test results or if the hepatitis B surface antigen is positive, further evaluation may be necessary.

What should I pay attention to when receiving the hepatitis B vaccine?
Under normal circumstances, when receiving the hepatitis B vaccine, it is important to confirm your own health status, screen for allergies, follow the vaccination schedule, monitor for post-vaccination reactions, and be aware of contraindications for special populations. After vaccination, it is necessary to keep the injection site clean and dry, and avoid scratching. In daily life, maintaining a regular作息 (routine), balanced diet, and moderate exercise can help enhance physical immunity and improve the protective effects of the vaccine.

How often should the hepatitis B vaccine be administered?
Under normal circumstances, the initial vaccination schedule for healthy individuals follows a 0, 1, 6 month program: the first dose is administered, followed by the second dose one month later, and the third dose five months after the second dose. Effective protective antibodies can be produced after completing the full vaccination series. Newborns, children, and adults who have never been infected with hepatitis B and test negative for antibodies should all follow this vaccination schedule.

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.
