What is the quantitative level of hepatitis B virus DNA?

Introduction

HBV DNA quantitative test is used to measure the viral load and activity of hepatitis B virus in the body. The normal value is less than 1000 copies/ml, indicating no current presence of hepatitis B virus in the body. However, if the value exceeds the normal range, it suggests an active infection with hepatitis B virus, and higher values indicate greater viral load and stronger infectivity.

Generally, the term "hepatitis B virus" refers to the hepatitis B virus (HBV). The normal reference value for hepatitis B virus DNA quantitative test is less than 1000 copies/mL (cps/ml). Detailed analysis is as follows:

The hepatitis B virus DNA quantitative test measures the amount of HBV nucleic acid in the body through specific detection methods, helping to determine the viral load and assess its activity. Normally, a hepatitis B virus DNA quantitative result of less than 1000 cps/ml indicates no presence of HBV in the body. If the test result is greater than 1000 cps/ml, it suggests the presence of HBV, and the higher the value, the greater the viral load, the more active the viral replication, and the stronger its infectivity.

It should be noted that different hospitals may use different units and therefore have different reference ranges. Additionally, the hepatitis B virus DNA quantitative test can only be used to evaluate viral load, not to determine the severity of the disease condition. Therefore, other tests should also be considered in combination for comprehensive analysis.

Male: 1345 positive; Female: 25 positive. Is it contagious?

A positive result of 1345 in males indicates hepatitis B virus infection with active viral replication, typically associated with high viral load. The virus may be present in bodily fluids such as blood and semen, posing a risk of transmission to others through blood exposure or sexual contact. Even in the absence of obvious symptoms, the virus can still spread through close personal contact, so preventive measures should be taken seriously.

Does receiving too many COVID-19 vaccines make one more likely to get hepatitis B?

The development and production of COVID-19 vaccines are based on antigens related to the SARS-CoV-2 virus. The vaccine components do not contain any substances related to the hepatitis B virus. Their mechanism of action is to stimulate the body to produce antibodies against the SARS-CoV-2 virus, and they cannot cause hepatitis B disease out of nowhere. The causative agent of hepatitis B is the hepatitis B virus, which spreads through blood, mother-to-child transmission, and sexual contact—none of which intersect in any way with the administration of COVID-19 vaccines.

Can chicken bone grass turn hepatitis B negative?

Chicken bone grass (Herba Abri) is a traditional Chinese herbal medicine known for its effects of promoting dampness elimination, relieving jaundice, clearing heat, detoxifying, and soothing the liver to alleviate pain. According to Traditional Chinese Medicine (TCM) theory, it is commonly used as an adjunct to improve symptoms associated with hepatitis B, such as discomfort in the liver region, fatigue, and jaundice. It can help reduce damp-heat stagnation in the liver to some extent, thereby creating a relatively favorable environment for liver metabolism. However, it is not a direct antiviral agent that kills or suppresses the hepatitis B virus.

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:

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.

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 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.
