Introduction

Non-transmissible hepatitis B usually refers to situations where individuals carrying the hepatitis B virus or those with chronic hepatitis B are not infectious under specific conditions. It is important to maintain a regular作息 (daily routine), avoid staying up late to prevent increased metabolic burden on the liver. Eat a light and balanced diet, reduce intake of high-fat, high-sugar, and spicy foods, and consume more fresh fruits and vegetables to supplement vitamins.

Non-infectious hepatitis B typically refers to situations where individuals who are carriers of the hepatitis B virus or have chronic hepatitis B are not contagious under specific conditions. The details are as follows:

Non-infectious hepatitis B usually refers to cases in which the hepatitis B surface antigen is negative and only the surface antibody is positive, or to chronic hepatitis B carriers with undetectable hepatitis B viral DNA. The former situation commonly occurs after vaccination, when protective antibodies are produced in the body. These antibodies prevent viral invasion, and since there is no active viral replication, the individual is not infectious. Although the latter group has been infected with the hepatitis B virus, the virus remains dormant, with extremely low or even undetectable levels of virus in the blood and bodily fluids. Therefore, transmission through common routes is not possible, making daily contact safe.

Maintain a regular作息 (daily routine), avoiding late nights that increase the liver's metabolic burden. Eat a light and balanced diet, reducing intake of high-fat, high-sugar, and spicy foods, and consume more fresh fruits and vegetables to supplement vitamins. Strictly limit alcohol consumption, as alcohol directly damages liver cells and may trigger viral reactivation. Regularly undergo liver function and viral testing to monitor changes in health status. Engage in moderate exercise to strengthen physical condition, but avoid intense physical activity, and maintain a positive mood, avoiding prolonged anxiety that could negatively affect liver health.

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.

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.
