Hepatitis B Surface Antigen

A Hepatitis B Surface Antigen (HBsAg) test detects the presence of HBsAg in your blood, which is one of the earliest indicators of a hepatitis B infection. A positive result may indicate an active hepatitis B infection and should be evaluated by a healthcare professional.

What It Measures

This test detects the hepatitis B surface antigen, a protein on the outer surface of the hepatitis B virus. HBsAg is one of the first detectable markers after infection and can indicate an acute or chronic infection. The test provides a qualitative result indicating whether the antigen is present in your blood.

Why It Matters

HBsAg is the hallmark marker for identifying active hepatitis B infection. A positive result persisting for more than six months may indicate chronic hepatitis B, which can lead to liver damage, cirrhosis, or liver cancer if left unmanaged. Early detection supports timely medical intervention and helps prevent transmission to others.

When to Test

Testing may be recommended for individuals at higher risk of hepatitis B infection, as part of routine prenatal screening, before starting immunosuppressive therapy, or when hepatitis B infection is suspected based on symptoms or exposure. Consult a healthcare professional for guidance.

Recommendations

Female

If Low

Negative result indicates no current Hepatitis B infection. Consider vaccination if not immune.

If High

Positive result indicates current Hepatitis B infection. Requires immediate consultation with hepatologist for treatment evaluation.

Lifestyle Tips

Protect your liver by limiting alcohol intake, maintaining a balanced diet, and exercising regularly. If you have not been vaccinated against hepatitis B, discuss vaccination with your healthcare provider. Avoid sharing needles, razors, or other personal items that may carry blood.

Frequently Asked Questions

What does a positive HBsAg result mean?

A positive HBsAg result means the hepatitis B surface antigen was detected in your blood, which may indicate an active hepatitis B infection. Further testing is needed to determine whether the infection is acute or chronic. Consult a healthcare professional for a full evaluation.

Can I have hepatitis B without symptoms?

Yes, many people with hepatitis B, particularly chronic hepatitis B, may not experience noticeable symptoms for years. This is why screening is important for individuals at higher risk. Regular monitoring by a healthcare professional can help detect and manage the infection early.
