Hepatitis B Surface Antigen Test Means

The Hepatitis B Surface Antigen (HBsAg) Test is a blood test used to detect the presence of HBsAg in the blood.

It is a vital screening tool to diagnose acute and chronic hepatitis B infections.
The test helps identify individuals who are currently infected with the hepatitis B virus (HBV), even if they are asymptomatic.
It is crucial for preventing the transmission of hepatitis B, as infected individuals can unknowingly spread the virus to others.
Early detection through the HBsAg test enables timely medical intervention and the initiation of appropriate treatment to manage hepatitis B, reducing the risk of complications and liver damage.

Hepatitis B Surface Antigen Test Purpose

The purpose of the Hepatitis B Surface Antigen Test is to:

Detect Hepatitis B infection.
Screen for chronic hepatitis B.
Assess liver disease risk.

Hepatitis B Surface Antigen Test Result

Reactive: A reactive result in the Hepatitis B Surface Antigen (HBsAg) Test indicates the presence of the Hepatitis B virus in the blood, suggesting an active infection.
Non-Reactive: A non-reactive result means that HBsAg is not detected in the blood, which typically indicates the absence of an active Hepatitis B infection.

Non-Reactive	Normal (Negative)
Reactive	Abnormal (Positive)

Hepatitis B Surface Antigen Test Reactive Results

Here are potential causes of a reactive Hepatitis B Surface Antigen (HBsAg) Test result.

Potential Causes	Description
Active Hepatitis B Infection	A reactive result typically indicates an active Hepatitis B virus infection.
Chronic Hepatitis B	Persistent presence of HBsAg may suggest chronic Hepatitis B.
Acute Hepatitis B	In the early stages of acute infection, HBsAg levels may be high.
Carrier State	Some individuals can carry the virus without symptoms, leading to a reactive HBsAg result.

Hepatitis B Surface Antigen Test Non Reactive Results

Here are potential causes of a non-reactive Hepatitis B Surface Antigen (HBsAg) Test result.

Potential Causes	Description
No Hepatitis B Infection	A non-reactive result indicates the absence of an active Hepatitis B virus infection.
Successful Vaccination	Vaccination against Hepatitis B can lead to non-reactive HBsAg results.
Past Infection and Recovery	Individuals who have recovered from Hepatitis B may show non-reactive results, although other markers like anti-HBc may be present.
False Negative Result	Rarely, a non-reactive result may occur in individuals with low viral loads or during the early stages of infection. Confirmatory tests may be necessary.

Hepatitis B Surface Antigen Test FAQ

What if Hep B surface antibody is positive?

A positive Hepatitis B surface antibody indicates immunity due to either past infection or vaccination. It protects against future HBV infections, and the person is not currently infected.

How serious is HBsAg positive?

HBsAg-positive status suggests an ongoing Hepatitis B infection. The seriousness varies; some may clear the virus naturally, while others develop chronic infection, which can lead to liver damage, cirrhosis, or liver cancer.

What are the 4 stages of hepatitis B?

Hepatitis B infection is often categorized into acute infection, immune response, chronic infection, and complications (cirrhosis or liver cancer). The progression varies, and not everyone goes through all stages.

Does hepatitis B go away?

Acute hepatitis B may resolve on its own, but chronic infection can persist for life. Medical management aims to control the virus and prevent complications, but complete eradication may not always occur.
