On July 28, 2026, World Hepatitis Day, the World Health Organization released regional figures from its Global hepatitis report 2026 and delivered an unusually blunt message: prevention is working, testing is not. In the WHO European Region, only 23% of people living with hepatitis B have ever been diagnosed, and just 4.2% are on treatment. The picture in the United States rhymes. More than half of Americans with hepatitis B do not know they have it, even though the CDC has recommended that every adult be screened at least once since 2023. That gap has a very ordinary explanation, and it shows up on your lab report: a hepatitis blood test is not part of routine bloodwork. It has to be ordered on purpose.
What the WHO reported on July 28
The findings cut both ways. Vaccination has driven hepatitis B prevalence among children under five in the European Region down to 0.06%, below the global elimination threshold of 0.1%. New hepatitis B infections have dropped 54% since 2015, new hepatitis C infections 28%, and hepatitis C mortality has fallen by a third over the past decade. Yet an estimated 9.7 million people are living with hepatitis B and 5.6 million with hepatitis C in the region, most of them undiagnosed. WHO’s own framing of the shift is worth quoting plainly: the biggest gap today is no longer prevention, it is finding people with hepatitis and getting them into care. Globally, hepatitis B and C still caused 1.34 million deaths in 2024, largely from cirrhosis and liver cancer that early detection could have prevented.
Why normal liver enzymes prove nothing
This is the misunderstanding that keeps millions undiagnosed. A standard लिवर फंक्शन पैनल (Liver Function Panel) measures enzymes: एएलटी, एएसटी, जीजीटी and alkaline phosphatase. Those numbers tell you whether the liver is under strain right now. They say nothing about why, and they can sit comfortably inside the reference range for years in someone carrying chronic hepatitis B or C. Roughly half to two thirds of people with acute hepatitis B have no symptoms at all, and chronic infection is quieter still: no fatigue worth mentioning, no jaundice, no pain, while scarring accumulates. Even the AST to ALT ratio, useful for sorting out some liver conditions, cannot rule a virus in or out. Detecting hepatitis requires looking for the virus itself and for the antibodies against it, which means serology, which means a separate order. If those lines are not on your report, the test was never run.
How to read a hepatitis B triple panel
Since 2023 the CDC has recommended that all adults aged 18 and older be screened for hepatitis B at least once using a triple panel, replacing the older single-test approach. The three components answer three different questions, and only the combination means anything. Hepatitis B surface antigen, or HBsAg, is a piece of the virus envelope: if it is there, the virus is there. Total antibody to hepatitis B core antigen, or total anti-HBc, is the permanent fingerprint of a real encounter with the virus, and it never appears after vaccination alone. Antibody to hepatitis B surface antigen, or anti-HBs, is the protective antibody produced after recovery or a successful vaccine series.
| HBsAg | Total anti-HBc | Anti-HBs | इसका क्या मतलब है |
|---|---|---|---|
| नकारात्मक | नकारात्मक | नकारात्मक | Never infected and not protected; vaccination is worth discussing |
| नकारात्मक | नकारात्मक | सकारात्मक | Immune from vaccination |
| नकारात्मक | सकारात्मक | सकारात्मक | Past infection, now resolved, with natural immunity |
| सकारात्मक | सकारात्मक | नकारात्मक | Active infection, acute or chronic; link to specialist care |
| नकारात्मक | सकारात्मक | नकारात्मक | Isolated core antibody: waning immunity, occult infection or a false positive; needs clarification |
Two traps are worth naming. A reassuring anti-HBs level says nothing about hepatitis C or hepatitis A, which are separate viruses with separate tests. And an isolated positive anti-HBc is not a result to file away: it is exactly the pattern that warrants a clinician’s interpretation rather than a search engine’s.
Hepatitis C works in two steps
The CDC also recommends hepatitis C screening once for every adult 18 and older, and during every pregnancy. That screen looks for HCV antibodies, and a positive result answers only half the question. Antibodies persist for life, including in the roughly one in four people who clear the virus on their own. Confirming whether the infection is still active requires an HCV RNA test, sometimes called a viral load. Antibody positive with RNA negative means a past, resolved infection. Antibody positive with RNA positive means active hepatitis C, which today is curable in the large majority of cases with a course of oral medication lasting a couple of months. The same logic of a screening test followed by a confirmatory test governs several other infections, including HIV.
What recent science changes for you
Three findings turn WHO’s message into something you can act on. First, a large German primary care study offered hepatitis B and C serology to more than 21,000 patients during ordinary check-ups. Among those who tested positive, 85% of hepatitis B infections and 65% of hepatitis C infections were completely unknown beforehand. Screening does not confirm suspicions, it uncovers. Second, a 2026 population survey in Belgrade measured the gap between what people believe and what their blood shows: 1.1% of participants reported a history of hepatitis B, while 8.7% carried the biological trace of exposure to the virus. Third, an international review evaluated a deceptively simple fix for hepatitis C called reflex testing, in which the laboratory automatically runs the RNA test on the same tube of blood as soon as the antibody test comes back positive, with no second appointment and no second blood draw. The practice clearly increases the share of patients who actually receive their confirmatory result, and it cuts the wait from weeks to under a day. The practical takeaway is direct: if your HCV antibody test is positive, ask whether the RNA test has already been run on the same sample rather than waiting for a follow-up visit that many people never make. Economic modeling points the same way, finding that a one-time hepatitis B screen for all adults is not only effective but likely cost-saving, which is precisely the reasoning behind the current CDC recommendation.
How to actually get tested
Asking is the whole trick. Hepatitis serology is not bundled into an annual physical or a comprehensive blood panel, so it needs to be requested by name: hepatitis B triple panel, and hepatitis C antibody with reflex to RNA. The CDC is explicit that anyone who requests hepatitis B testing should receive it regardless of whether they disclose a risk factor, precisely because risk questions are stigmatizing and unreliable. The draw itself is an ordinary one, no fasting required, and it can be combined with other routine blood work. Results generally come back within a few days, on a timeline comparable to most laboratory tests. And if your enzymes are elevated with no clear cause, viral hepatitis deserves to be formally ruled out before settling on fatty liver disease, now the most common explanation for abnormal liver numbers.

- Serology: a blood test that looks for viral antigens or the antibodies made against them, to establish whether an infection has occurred.
- HBsAg: hepatitis B surface antigen, a fragment of the virus envelope; its presence means the virus is present.
- Anti-HBc: antibody against the hepatitis B core, a lifelong marker of genuine exposure that never follows vaccination alone.
- Anti-HBs: the protective hepatitis B antibody, present after recovery or a successful vaccine series.
- HCV RNA or viral load: a test that looks for the virus’s own genetic material, to determine whether the infection is still active.
- Reflex testing: an arrangement in which the laboratory automatically runs the confirmatory test on the original sample when the screening test is positive.
अक्सर पूछे जाने वाले प्रश्नों
Is a hepatitis test included in routine bloodwork?
No. Routine panels measure liver enzymes, not viruses. Hepatitis serology must be ordered specifically. If you do not see HBsAg, anti-HBc and anti-HBs on your report, or an HCV antibody line, the screening simply was not performed.
My liver enzymes are normal, so can I rule out hepatitis?
No. Chronic hepatitis B and C commonly run for years with ALT and AST inside the reference range. That is the rule rather than the exception, and it is exactly why screening relies on serology instead of the liver panel.
What does a positive anti-HBs with a negative anti-HBc mean?
That combination usually reflects immunity from vaccination: the body produced the protective antibody without ever meeting the virus itself. It is the expected result in a fully vaccinated adult and requires no further action.
Who should be screened for hepatitis in the United States?
The CDC recommends that every adult aged 18 and older be screened once for hepatitis B using a triple panel and once for hepatitis C, plus hepatitis C screening during each pregnancy. People with ongoing exposure risks, including a history of injection drug use, dialysis, or living with an infected household member, should be tested periodically.
