Hepatitis B Panel — What Your Blood Test Result Means

ScanHealth Learn Infectious Disease Hepatitis B Panel

Hepatitis B Status Check

The hepatitis B panel uses three markers to tell a complete story: HBsAg (surface antigen—are you currently infected?), anti-HBs (surface antibody—are you immune?), and anti-HBc (core antibody—have you ever been exposed?). Together they reveal whether you're infected, immune from vaccine, immune from past infection, or susceptible.

What is Hepatitis B Panel?

Standard panel: HBsAg (infection marker), anti-HBs (immunity marker, >10 mIU/mL = immune), anti-HBc total (exposure marker). Additional markers: HBeAg (high infectivity), anti-HBe (lower infectivity), HBV DNA viral load (replication level).

What High Hepatitis B Panel Means

HBsAg positive = active hepatitis B infection (acute or chronic). Anti-HBs positive only = immune from vaccination. Anti-HBs + anti-HBc positive = immune from past infection. Anti-HBc alone = past infection (unclear immunity) or occult HBV.

Common symptoms:

Acute: jaundice, fatigue, nausea, abdominal pain, dark urine (many are asymptomatic) · Chronic: often asymptomatic for decades until cirrhosis develops · Cirrhosis: fatigue, jaundice, ascites, variceal bleeding

What Low Hepatitis B Panel Means

N/A—these are qualitative markers.

Why It Matters

When normal:

Determines infection status, immunity, and susceptibility

Guides vaccination decisions

Chronic HBV needs monitoring for liver cancer (HCC)

HBV is preventable with vaccination

Risks if abnormal:

Chronic HBV: cirrhosis, liver failure, hepatocellular carcinoma

Vertical transmission: mother to child during birth

Reactivation risk with immunosuppression (rituximab, chemotherapy)

What Can Cause Abnormal Levels?

Hepatitis B Virus Infection

100% likely

Transmitted via blood, sexual contact, and vertical (mother-to-child). 95% of adults clear acute infection; 90% of neonates become chronic.

Perinatal Transmission

Most common route worldwide. HBV vaccine at birth prevents this.

Sexual Transmission

Major route in adults.

Blood Exposure

Needlestick, IV drug use, tattooing, transfusion (rare now).

What You Can Do

If all negative (susceptible): get vaccinated (3-dose series)

Impact: Vaccination is >95% effective at preventing HBV \u00B7 Timeline: 0, 1, 6 months

If HBsAg positive: determine acute vs chronic (repeat in 6 months)

Impact: HBsAg positive >6 months = chronic hepatitis B \u00B7 Timeline: 6 months

If lifestyle changes aren't enough:

If chronic HBV: HCC surveillance (AFP + ultrasound q6 months)

Impact: Chronic HBV increases HCC risk even without cirrhosis \u00B7 Timeline: q6 months

Check HBV DNA viral load and HBeAg status

Impact: Guides treatment decisions \u00B7 Timeline: At diagnosis

Recommended retest: Chronic HBV: ALT and viral load q6-12 months; HCC screening q6 months
