What does it mean to be positive for hepatitis B markers 2, 4, and 5?

Introduction
HBsAg negative, anti-HBs positive, HBeAg negative, anti-HBe positive, anti-HBc positive — that is, positivity in the second (surface antibody), fourth (e antibody), and fifth (core antibody) items of the five-item hepatitis B panel. This situation commonly occurs after a previous hepatitis B virus infection, during which the body's immune system initiated a response, gradually cleared the virus, and simultaneously produced surface antibodies. The surface antibody is a protective antibody capable of defending against reinfection by the hepatitis B virus.

Generally, a positive result for hepatitis B items 2, 4, and 5 indicates past infection with the hepatitis B virus, which has since been cleared from the body, accompanied by the development of protective antibodies. This means the individual is not currently suffering from hepatitis B. If there are any concerns, it is recommended to seek medical advice in advance. The detailed explanation is as follows:

A positive result for hepatitis B items 2, 4, and 5 refers to positivity for the second item (hepatitis B surface antibody), the fourth item (hepatitis B e-antibody), and the fifth item (hepatitis B core antibody). This situation commonly occurs after a previous hepatitis B virus infection, during which the body's immune system activated an immune response, gradually eliminating the virus and simultaneously producing surface antibodies. The surface antibody is a protective antibody that can defend against reinfection by the hepatitis B virus, indicating that the body has entered a recovery phase and is no longer infectious.

In rare cases, if the patient is in the early stage of viral clearance, there may be extremely low levels of residual virus present. However, over time, the virus is typically completely eliminated and the level of surface antibodies gradually increases. Such individuals do not require special treatment but should undergo regular follow-up testing of the five-item hepatitis B panel to monitor surface antibody titers, ensuring they remain at an effective protective level and preventing increased risk of infection due to insufficient antibody levels.

Individuals with positive results for hepatitis B items 2, 4, and 5 should have regular check-ups including the five-item hepatitis B panel and liver function tests to monitor changes in surface antibody titers. They should maintain healthy daily habits, avoid alcohol consumption and medications that may cause liver damage. If antibody titers are found to be too low, they should consult a doctor to determine whether a vaccine booster dose is needed to enhance protection.

What are the indicators of immunity acquired after hepatitis B virus vaccination?
Immunity acquired after hepatitis B virus vaccination can be determined through serological testing, which generally includes the following indicators: positive hepatitis B surface antibody (HBsAb), HBsAb titer ≥10 mIU/mL, HBsAb titer ≥100 mIU/mL, seroconversion rate of anti-HBs, and negative hepatitis B surface antigen (HBsAg). A detailed analysis is as follows:

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.

What are the symptoms of hepatitis D?
In general, hepatitis D, a liver disease caused by the hepatitis D virus, often coexists with hepatitis B infection. 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.
