🟡 What to Do After a
Hepatitis B Positive (HBsAg+) Result

A clear, step-by-step guide — written by clinicians, not algorithms.

A positive HBsAg test means Hepatitis B virus is currently in your blood — but it does not tell you yet whether the infection is new (acute) or long-term (chronic), or how active it is. 90–95% of adults who acquire Hepatitis B clear it naturally within 6 months without treatment.

What This Result Actually Means

HBsAg (Hepatitis B surface antigen) is the outer protein coat of the Hepatitis B virus. A positive result means the virus is present in your blood. What this means depends on how long you have been infected: Acute Hepatitis B (less than 6 months) — 90–95% of adults clear this without treatment. Chronic Hepatitis B (more than 6 months) — the 5–10% of adults whose immune system cannot clear the virus. Chronic carriers face long-term liver risks including cirrhosis and liver cancer, which is why monitoring matters enormously. The next step is a full Hepatitis B panel — not just the HBsAg — to understand the stage and activity of your infection.

Your Next Steps — In Order

1
Get a full Hepatitis B panel — not just HBsAg
A full panel includes: HBeAg (whether the virus is actively replicating), Anti-HBe (immune response to replication), HBV DNA (viral load) (how much virus is circulating), Anti-HBs (protective antibody — if positive, the infection is clearing), and Anti-HBc IgM (IgM = acute infection; IgG = past or chronic). This panel tells your doctor whether you are in the acute, immune-active, or inactive carrier phase.
2
Get a liver function test (LFT)
Measure ALT (alanine aminotransferase) and AST — liver enzymes that rise when the liver is inflamed. Elevated ALT in a Hepatitis B carrier indicates active liver damage and is a key indicator for starting antiviral treatment.
3
Get a liver ultrasound
An abdominal scan assesses liver size, texture, and structure. It detects early cirrhosis (irregular surface, nodular appearance) and screens for hepatocellular carcinoma (HCC). Carriers are at 100× higher risk of liver cancer — regular liver ultrasound is the primary screening tool.
4
Vaccinate all household contacts and sexual partners immediately
Hepatitis B is 50–100 times more infectious than HIV. Household contacts (sharing razors, toothbrushes, or exposure to blood) and sexual partners must be tested and vaccinated without delay. The 3-dose vaccine series is highly effective. Unvaccinated contacts who have had recent high-risk exposure should receive Hepatitis B immunoglobulin (HBIG) plus the first vaccine dose within 24 hours.
5
Start antiviral therapy if indicated
Not all Hepatitis B carriers need antiviral treatment. Treatment is indicated when: HBV DNA is high, ALT is persistently elevated, or liver biopsy/Fibroscan shows significant fibrosis.
6
Schedule regular monitoring for life
Chronic Hepatitis B requires lifelong monitoring: HBV DNA and liver function every 6 months, liver ultrasound every 6 months (HCC surveillance), and ALT every 3 months initially. This monitoring saves lives — HCC caught early is curable.

Frequently Asked Questions

Does Hepatitis B always lead to liver cancer?
No — the lifetime risk of liver cancer in a chronic Hepatitis B carrier is approximately 15–40%, depending on viral load, liver inflammation, alcohol use, and whether cirrhosis develops. This is significantly higher than the general population, which is why surveillance is essential. However, the majority of chronic carriers with well-controlled viral replication (either by natural immune control or antiviral treatment) and regular monitoring never develop liver cancer. Early detection when HCC does develop improves outcomes dramatically.
Can I get rid of Hepatitis B completely?
For acute Hepatitis B in adults: yes — 90–95% of adults naturally clear the infection within 6 months, develop protective anti-HBs antibodies, and are immune thereafter. For chronic Hepatitis B: true cure (HBsAg loss) occurs in only about 1–3% of treated patients per year. Antiviral therapy (tenofovir) suppresses the virus to undetectable levels but does not eliminate it from the liver — it is a form of viral control, not cure. Research into cures for chronic Hepatitis B is very active.
Is it safe to breastfeed with Hepatitis B?
Yes — breastfeeding is safe for a mother with Hepatitis B if the baby receives proper prophylaxis at birth. The baby should receive the Hepatitis B vaccine plus Hepatitis B immunoglobulin (HBIG) within 12 hours of birth. With this combination, the risk of mother-to-child transmission through breastfeeding is very low. Mothers on tenofovir can also breastfeed safely — tenofovir passes into breast milk in very small amounts and is not harmful to the infant.
My partner tested positive — am I infected?
Not necessarily — but you need to be tested. If you have been vaccinated and completed the 3-dose series, you are likely protected. A blood test (Anti-HBs) can confirm immunity. If unvaccinated, you need an HBsAg and Anti-HBc test to determine your status. If you are susceptible (negative on all markers), start the vaccine series immediately — and consider HBIG if sexual contact was recent (within 14 days).
