Introduction

The normal value for hepatitis B generally refers to the result of a blood test measuring hepatitis B DNA. A hepatitis B DNA level below 500 U/mL is considered normal. If the level exceeds 500 U/mL, it may indicate that the patient is infected with the hepatitis B virus. For individuals who are hepatitis B carriers, we recommend undergoing liver disease screening every six months. The purpose of these check-ups is to monitor for the development of hepatitis, liver fibrosis, cirrhosis, or even liver cancer.

The normal value for hepatitis B generally refers to the result of a blood test measuring hepatitis B DNA. A hepatitis B DNA level below 500 U/mL is considered normal. If the level exceeds 500 U/mL, it may indicate that the patient has a hepatitis B virus infection. It is recommended that individuals carrying the hepatitis B virus undergo liver disease screening every six months to monitor for potential development of hepatitis, liver fibrosis, cirrhosis, or even liver cancer.

Carriers of hepatitis B who do not experience active hepatitis flare-ups do not require medication. However, if abnormal liver function or elevated transaminase levels occur, hepatoprotective and antiviral treatments should be initiated under a doctor's guidance. This may include taking antiviral medications as prescribed, such as entecavir tablets or tenofovir alafenamide fumarate tablets, which can suppress hepatitis B virus replication, slow the progression of liver fibrosis and cirrhosis, and reduce the risk of developing liver cancer.

Patients with chronic hepatitis B need to take medication long-term and must not discontinue treatment on their own. Premature discontinuation may lead to withdrawal symptoms, causing rebound viral replication and rapid deterioration of liver function.

Can short-acting interferon be used again after having been administered for 4 years and then discontinued for 4 years?

If the underlying disease (e.g., chronic hepatitis B or C) is currently in an active phase, with abnormal liver function or elevated viral load, and no severe baseline conditions (e.g., cirrhosis) have occurred during the 4-year period off treatment, the patient may be eligible for re-treatment—provided a physician evaluates them as having good overall tolerance and no contraindications to interferon use (such as severe cardiac or renal disease, or psychiatric history). An individualized dosing regimen would then be required.

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.

What is lymph node metastasis of liver cancer?

Under normal circumstances, lymph node metastasis of liver cancer may be caused by factors such as aging, chronic sleep deprivation, chronic hepatitis B, liver cirrhosis, and biliary tract infections. If discomfort symptoms occur, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. In daily life, one should avoid staying up late and excessive fatigue; receive hepatitis B vaccination to prevent hepatitis B infection.

How many weeks should expectant fathers go for infectious disease screening?

The prospective father should undergo infectious disease screening 3–6 months before conception, including key tests for hepatitis B, hepatitis C, syphilis, and HIV. These screenings help detect infections early, prevent mother-to-child transmission during pregnancy, and protect the health of both mother and baby. If abnormal results are found, prompt medical consultation at a正规 hospital is necessary. Infectious disease screening during the preconception period is an essential step for achieving healthy pregnancy and optimal child development.

How soon can I get tested for the four major infectious diseases after being pricked by a used needle?

Some infectious diseases have a window period, during which a positive result cannot be detected immediately after infection. For example, the window period for HIV is typically 2–4 weeks, and for hepatitis B it is about 1–6 months. If testing is performed immediately after exposure, a false-negative result may occur due to the ongoing window period, making it impossible to accurately determine whether infection has occurred. Therefore, retesting after the window period is recommended as advised by a physician.

Is early-stage liver cirrhosis caused by hepatitis B severe?

Early-stage hepatitis B-related cirrhosis is a serious condition. If not promptly intervened, it will progressively advance to decompensated cirrhosis or hepatocellular carcinoma, endangering life. At this stage, irreversible liver fibrosis has already occurred, necessitating immediate medical attention and standardized treatment. The severity of early-stage hepatitis B-related cirrhosis lies in the destruction of liver structure and impairment of liver function, driven by persistent viral replication and chronic inflammation.

What is the most common cause of cirrhosis?

There is no such thing as "the most common cause of cirrhosis." Common causes of cirrhosis include viral hepatitis, alcoholic liver disease, non-alcoholic fatty liver disease, autoimmune liver disease, drug- or toxin-induced liver injury, etc. If symptoms such as fatigue, jaundice, or ascites occur, seek medical attention promptly for accurate diagnosis. 1. Viral hepatitis: Chronic infection with hepatitis B or hepatitis C virus is a major contributing factor.

Foods and fruits that are good for hepatitis B

Foods and fruits beneficial for hepatitis B include those rich in high-quality protein, vitamins, dietary fiber, low fat, and liver-protecting minerals. Proper intake can help support liver function. If symptoms such as discomfort in the liver area or jaundice occur, prompt medical attention is necessary. For example, eggs, milk, lean meat, and soy products provide essential materials for liver cell repair.
