Hepatitis B Screening in China: Testing, Vaccination and Long-Term Liver Care for Foreign Residents

The result that arrives in Chinese, with no line you can read

Shenzhen, 9:40 on a Tuesday morning. A man from Lagos who has worked in the city for two years finally books the appointment he has been putting off, sits in an outpatient waiting room on the fourth floor, and gets a printed sheet back four days later. Three of the five lines on it say one character over and over. He photographs the paper, sends it to his sister in Enugu, and gets three different answers in three different dialects. Nobody around him at work mentions hepatitis B, so nobody says out loud that a positive line on that sheet is a chronic condition you manage, not an emergency, and it is measured in decades rather than days.

That is the conversation this page is meant to have. Hepatitis B comes up in a foreigner’s life in China for four reasons: a pre-employment or residence medical exam, a family health check, a routine blood test that happens to include liver markers, or a real episode where you want to know whether a contact put you at risk. The testing system that answers those questions is old, well funded and good at what it does, and it is also written almost entirely in Chinese, priced in yuan, and run on a queue that rewards people who understand how to book it.

This guide walks through the panel itself, how to get it ordered at a public hospital, what each marker means in plain language, when a positive result means vaccination for the people around you rather than tablets for you, what the long-term follow-up looks like, and roughly what it all costs. Every price below is an estimate. Estimates only — final costs are determined by the hospital.

I am a health management practitioner and a medical escort who works with foreign patients in southern China. I have stood beside people in that fourth-floor waiting room. What follows is the explanation I give them, adjusted so that it also works if you are reading it before you ever set foot in the country.

What a hepatitis B screen actually measures

The panel most Chinese hospitals run for hepatitis B is called the five-marker panel, and it looks at five different things your immune system does to the virus. It is not one test with one result. It is five results that have to be read together, which is why the sheet carries five columns next to five Chinese labels.

The five markers are:

1. HBsAg — hepatitis B surface antigen. This is the virus’s outer shell. If this line reads positive, the person is infected, whether or not anything hurts.
2. Anti-HBs — antibody to the surface antigen. This is the good one. It means the immune system met the virus and won. It is what vaccination produces.
3. HBeAg — e antigen. A marker of active viral replication. Positive here usually means a higher viral load, not automatically a worse outcome.
4. Anti-HBe — antibody to the e antigen. Usually a sign replication has slowed down.
5. Anti-HBc — antibody to the core antigen. If this is positive, the person has been or is infected. A separate IgM version of this antibody is used to work out whether an infection is fresh or something you have carried for years.

Read together, the combinations separate four very different situations: never exposed and unvaccinated; immune and protected from vaccination; resolved infection from the past where you carry antibodies and cannot reinfect yourself; and current infection, which may still be either an acute episode you are fighting off or a long-standing carrier state that needs monitoring.

The five-marker panel is a screen, not a treatment decision. Two more pieces of information usually change the picture. The first is a quantitative HBV DNA result from a real-time PCR assay, which tells you the actual viral load in international units per millilitre and sets the reference range your lab uses — some report below 500 IU/mL, some below 20. The second is a liver enzyme panel, especially ALT, since a rising ALT over time is what tells a hepatologist that viral replication is causing inflammation rather than sitting quietly.

For someone deciding what to ask for, that means the minimum useful order is the five-marker panel plus ALT, and the useful full order adds HBV DNA. Ultrasound and elastography belong to the follow-up stage, not the first screen.

Booking the test: how a public hospital appointment in China works

Public tertiary hospitals in Chinese cities run a liver clinic inside either the infectious disease department, the gastroenterology department, or a combined hepatology clinic. All three will order the panel. Which one you end up in depends on the hospital.

Book through the hospital’s own WeChat account or its official appointment app, or through the municipal platform — Shenzhen residents use the city’s public health mini-programme, other cities have their own equivalents. Registration opens a fixed number of days ahead, in most Shenzhen hospitals about seven days, and the morning batch releases around 08:00. Miss it and the same clinic is usually walk-in only before 07:30, which is brutal if you are not a morning person and do not speak the language.

Three practical details save a second visit:

• Go fasting. The liver panel, the ultrasound and often the HBV DNA draw all want a fasting appointment. Book the earliest slot of the day, bring water you drink only after the blood draw, and expect the phlebotomy window to close at roughly 10:00.
• Take your passport. Registration and the lab system key on the ID you used to register, not on your Chinese residence card number. If your passport is gone, the registration desk can usually still issue a temporary registration card, but it takes a little time.
• Say the words. The exact request you want is the five-marker hepatitis B panel with a liver function panel and quantitative HBV DNA — but you should not have to say that in Chinese. Point at the lab’s own printed list of items, or write the English names on a card and hand it to the nurse. Chinese hospital staff read English names of tests every day.

Turnaround is realistic to plan around: markers and liver enzymes usually come back in one to two working days, PCR viral load in two to four, imaging a few days after that if it was booked separately. If you need the whole package at once, ask for it on the first visit rather than coming back for results you could have ordered together.

Where to go depends on the city. In Shenzhen, the city’s infectious disease centre and the hepatology clinic at Peking University Shenzhen Hospital both handle this routinely and are used to foreign patients. In Beijing, the infectious disease hospitals on the eastern side of the city have decades of liver caseloads. In Shanghai, the liver centres attached to the major teaching hospitals read reports from all over the country. Outside the big four, the gastroenterology department of any provincial first-class hospital can order the same panel. What differs between them is waiting time and whether a hepatologist will personally read your report.

Reading a five-marker panel that is printed in Chinese

The printed sheet has Chinese column headers, one row per marker, and cells marked either positive or negative. The single most useful thing to know is that in Chinese lab reports the positive symbol is written as the character for “yang” and the negative as the character for “yin”. It appears under the marker label, so the row reads as, for example, surface antigen yang.

The second thing is that a five-marker sheet alone does not tell you viral load, and it never says whether your liver is damaged. People assume a panel with one positive line means a mild case. What the pattern tells you is the infection state. What the ALT and HBV DNA tell you is the activity. Those are separate questions and they get read separately.

Third: the sheet is a record, and you own a copy of it. Most public hospitals in China now issue a printed report and, in many cases, an electronic one you can pull up under your registration ID. Photograph it the day you collect it. The pattern every expat panics about is the so-called “big three positive” and “small three positive” phrasing, which describe the e-antigen-positive and e-antigen-negative patterns respectively. Both describe chronic infection. Neither one, on its own, tells you whether you need medicine.

If you want the sheet read by someone else rather than interpreted from a phone screenshot, this is where the guide on understanding Chinese medical report is worth opening before you try to machine-translate it word by word. Translation software will happily render the label rows and quietly miss the fact that one of your antibodies uses a two-character word meaning immunoglobulin M. What looks like one result is sometimes two.

A positive result does not automatically mean treatment

This is the part that reassures people most and the part most search results get wrong. Being hepatitis B positive is not the same as having hepatitis B disease requiring tablets. A large share of people who test positive are what clinicians call inert carriers. Their virus is present, their liver enzymes are normal, their viral load is low, and they need observation rather than medication.

Treatment with an oral antiviral is usually considered when viral replication is substantial, the liver enzymes are persistently above the reference range, and a liver stiffness measurement or biopsy shows real fibrosis — or when cirrhosis is already present, in which case treatment starts regardless of the enzyme numbers. A hepatologist makes that call using the viral load, the ALT trend over several visits, the elastography reading and sometimes a biopsy. Nothing about that decision can be settled from one blood draw.

The medicines that come up are entecavir and tenofovir, both approved by China’s National Medical Products Administration and sold at public hospital pharmacies as both branded and generic versions. Both are taken once a day. Tenofovir disoproxil fumarate needs a kidney function check before and during use, and some people on it notice bone density changes over years, which is why tenofovir alafenamide exists as an alternative. Pegylated interferon is a different option for carefully selected patients and carries a real side-effect profile; it is generally not used in advanced cirrhosis or pregnancy.

One thing has to be said plainly, because it prevents a great deal of disappointment. Oral nucleoside analogues hold replication down and hold liver damage down. They do not clear the virus from most people. HBsAg loss on long-term oral treatment happens in a small minority, and it is a target that gets discussed year by year, not a promise attached to starting a tablet. Any clinic that tells you a course of tablets, injections, supplements or cell therapy will get you rid of hepatitis B is selling something.

What “management” means in practice is a schedule. For a person who is positive but stable, that is usually a six-monthly review: viral load, ALT, and an abdominal ultrasound, plus an elastography measurement at the start and after a few years. If cirrhosis is present or suspected, hepatocellular carcinoma surveillance with a six-monthly ultrasound and alpha-fetoprotein becomes part of the plan. Between reviews, the important number to watch at home is ALT if you have your own readings, along with anything that looks like new or worsening jaundice, a spread of swelling into the ankles, or deep and unusual tiredness.

Adult hepatitis B vaccination in China

Vaccination is the good endpoint of this whole guide, and China’s programme around it is more advanced than most people arriving here expect. Hepatitis B vaccine has been given to Chinese newborns within the first day of life as part of the national immunisation programme for a long time, and that birth dose is free. The effect on childhood chronic carriage has been substantial and is one of the quieter public health successes in the country. The consequence for a foreign adult is simple: if you grew up somewhere without a newborn birth-dose programme, you may have no cover at all, and that is fixable.

The adult course is three doses. The standard schedule is month zero, month one and month six. A shortened schedule of months zero, one and two exists when travel timing forces it, and a four-dose accelerated course at zero, seven and twenty-one days with a twelfth-month dose is used where protection is needed fast. Most community health centres and centres for disease control in each district run the vaccination clinic, walk in, and give you a small yellow card recording the doses.

Adult doses come in two strengths: 10 micrograms and 20 micrograms. Healthy adults usually get the standard dose. Thirty years and older, people on dialysis, and anyone with a weaker immune response are commonly offered the 20 microgram preparation, because the seroprotection rate after three standard doses in older adults is lower than in young adults. Dialysis patients are sometimes pitched on a 40 microgram dose on a schedule of three doses at zero, one and two months.

How success is measured: six months after the third dose, blood is checked for anti-HBs and a level of 10 mIU/mL or above is regarded as protective. Above that threshold, the standard advice is that no further doses are needed, and there is no schedule of boosters for the general population. If the response falls below the threshold, the usual response is to complete a course with the 20 microgram preparation and re-test, rather than to keep adding doses indefinitely.

Two situations change the plan. If your screen shows you are already HBsAg positive, vaccination will not help you and should not be given. If you have been exposed to a known positive partner or needle stick in the last hours, the window that matters is post-exposure prophylaxis, which means hepatitis B immune globulin plus vaccine, and it has to start quickly — inside roughly 24 hours, with the vaccine doses continuing afterwards. That is an emergency room conversation, not a clinic appointment to book next week.

Vaccination is also the family conversation. Hepatitis B spreads through blood, unsafe medical and cosmetic procedures, and sexual contact, and from mother to baby at birth. It does not spread through sharing a meal, hugging, kissing, sitting in the same office, swimming in the same pool, or mosquito bites. Getting that right stops people treating a colleague or a child as a hazard.

Living with chronic hepatitis B in China: the six-month rhythm

Settling in China with a positive result raises ordinary questions that are rarely answered: who do I see, how often, what gets monitored, what does it cost month to month, and does it follow me home. The rhythm below is what stable chronic infection usually looks like, and it is worth knowing before your first visit so that you can tell whether the clinic is on track.

• Every six months: HBV DNA, ALT and AST, kidney function if you are on or about to start tenofovir, an abdominal ultrasound, and a review of any new medicines or supplements you take.
• Annually, or at clinic discretion: liver elastography (FibroScan or equivalent transient elastography), alpha-fetoprotein if cirrhosis is on the table, and a review of your alcohol and weight, both of which matter more than most people expect for a liver.
• Specifically if cirrhosis is present: six-monthly ultrasound plus alpha-fetoprotein for liver cancer surveillance, and a conversation about a low-sodium diet, plus vaccination against hepatitis A if you never had it.
• If you are on treatment: viral load at roughly three months to confirm the fall, then every three to six months, done alongside a kidney and bone density review at annual intervals for tenofovir disoproxil fumarate.

On cost and access: the reviews above are ordinary outpatient work. A consultation with a hepatology or infectious disease specialist at a public tertiary hospital in a tier-one city typically runs a few tens of yuan with a specialist surcharge on top; blood work comes to a few hundred yuan per review; elastography sits a bit higher. Outpatient medicine lists are printed at the clinic and stocked in the hospital pharmacy. If you are employed in China, your employer can normally enrol you in the urban employee basic medical insurance scheme, and whether oral antivirals are covered depends on your city’s formulary — ask HR before you assume either way, and ask the hospital’s finance office for the itemised cost list if you need a document for your own records or for a future insurer.

For people who want a single place to hold all of this rather than bouncing between the infectious disease clinic, the test centre and a private clinic, that is exactly what a chronic disease care clinic in China is set up for: one file, one doctor who knows the last six sets of results, and a follow-up interval printed on a card.

One disclosure, so the reading is straightforward: I am also an advisor to the Zhong An Kang Hua jian kang men zhen clinic, which is a Chinese clinic rather than a hospital. Nothing on this page is a recommendation for any particular clinic, and nothing here should be read as a treatment plan. Other providers in the same city will give comparable advice.

Families, work permits and the school form

Three practical situations push foreign residents into this testing, and each one has a different rule.

The first is the work permit. The medical exam behind a China work permit is run at a hospital the immigration authority designates, for a defined list of communicable disease markers, and the exact panel depends on the category of application and the hospital doing it. It is not the same thing as a screening panel for your own liver. If you need to know what your specific form requires, the detail on the work visa health certificate in China is the place to start. What I would add from the testing side: if your exam does include liver markers and one comes back positive, that is a health finding for you, not automatically a disqualification, and the people who decide those cases are used to seeing a positive HBsAg.

The second is family. If you are positive and starting a family in China, the part that matters is that mother-to-child transmission is the single biggest route of chronic infection in the region, and it is preventable. That conversation belongs with your obstetric team and hepatologist early in pregnancy, not at delivery. If you are the partner and you are negative, your cover comes from vaccination, and it is worth doing before the baby arrives rather than after.

The third is school. International school enrolment forms in Shenzhen and elsewhere sometimes ask for an immunisation record or an immunity declaration, and an anti-HBs result is the evidence that answers it. Having a printed, translated report in the file saves the registrar a week.

What the tests cost and what to take home

Prices are in yuan at public hospital outpatient prices and are estimates. Estimates only — final costs are determined by the hospital. Use them to budget, not to shop.

• Five-marker hepatitis B panel: roughly 100 to 200 yuan.
• HBV DNA, quantitative PCR: roughly 120 to 300 yuan.
• Liver enzyme and liver function panel including ALT, AST and bilirubin: roughly 80 to 180 yuan.
• Abdominal ultrasound: roughly 150 to 300 yuan.
• Transient elastography: roughly 200 to 450 yuan.
• Alpha-fetoprotein: roughly 40 to 90 yuan.
• Specialist or senior specialist consultation: roughly 30 to 300 yuan depending on the hospital and the seniority of the doctor.
• Adult hepatitis B vaccine per dose: tens of yuan at a community health centre, more at a private clinic. Three doses together land in the low hundreds.

What to take home matters more than the bill. Collect: the printed five-marker report, the viral load report with its reference range printed on it, every ALT result with its date, the elastography number with the measurement scale stated, and the hospital’s itemised cost list. A set of dated numbers is what lets a doctor in another country read your case. A single positive line in a screenshot is not.

If any of this is going into a foreign insurer or a visa file, get the diagnosis and investigation sections stamped or issued as a formal diagnosis certificate rather than a lab printout. Many public hospitals issue one on request, usually with the treating doctor’s signature and the hospital seal, and there is usually a small fee. The hospital medical records office holds a copy for years and can reissue materials if you lose them after you fly home.

Six mistakes that cost the most time

• Testing at a private clinic and expecting a specialist to read it. Private clinics will draw blood. The interpretation and the elastography belong in hospital imaging and lab departments.
• Coming back for a second visit instead of ordering the full panel once. Markers, viral load and liver enzymes on day one, on fasting, with the imaging booked at the same time, is one trip.
• Assuming a positive result means you need tablets now. Sometimes it does, sometimes it needs monitoring, and the deciding evidence is a viral load trend plus an ALT trend over time, not a single line.
• Skipping the family conversation. Vaccinating a negative partner and planning for delivery is far easier than dealing with a new infection in a household.
• Buying antivirals or liver “detox” products abroad or online. Anti-viral tablets are prescription medicine, and unregistered products sold for liver health are exactly the kind of thing that can damage the organ you are trying to protect.
• Throwing away the reports. You will be asked for old results in three years, and the hospital archive will not be able to find a test done before you left.

Frequently asked questions

Do I need to be sick for a hepatitis B test?

No. The panel is one of the most common pieces of routine screening in China. People order it as part of a general health check, before a marriage or pregnancy registration, for a job application, or because a household member tested positive. It is a blood draw, and nothing about requesting it implies you think you are infected.

How long after exposure can the test still be useful?

Markers take weeks to appear after infection, so a test done in the first few days after a known exposure, a needle stick or a sexual contact may read negative and then need repeating. In practice Chinese hospitals will re-test at roughly three to six months for that scenario. If you are within about 24 hours of a real exposure, treatment to prevent infection is the priority and goes through the emergency department, not through a screening clinic.

Is it true that hepatitis B can be cured?

For acute infection, most adults recover fully without treatment and the virus clears. For chronic infection, oral antiviral medicines suppress replication very effectively and protect the liver over the long term, but they clear the surface antigen in only a small minority of people. Any clinic promising a cure, a stem cell route or a “detox” cure for chronic hepatitis B is outside mainstream medicine, and the claim should end the conversation.

Can my employer or the government see my result?

Hepatitis B is a notifiable infectious disease in China and public hospitals report coded cases to the disease control system, which is how the national picture is compiled. That is a population statistic. Your hospital record is yours, and the report is issued to you. Cases of employers or insurers using a positive screening result to deny you care or lawful work are worth reporting; China’s patient rights framework gives you a route to contest that.

A Note on Scope and Affiliation

This page explains how hepatitis B screening, vaccination and long-term follow-up work inside the Chinese public hospital system, written for foreign residents and medical travellers. It is general information, not medical advice for your specific case. Chronic hepatitis B affects differently depending on viral load, liver histology, age, kidney function, alcohol use and co-infection with hepatitis C, hepatitis D or HIV. Every decision about whether to start treatment, which medicine to use, how often to monitor, or whether hepatitis B immune globulin is appropriate in your situation belongs to a qualified hepatologist or infectious disease physician who has seen your results.

I am an advisor to the Zhong An Kang Hua jian kang men zhen, a clinic in China with which I am affiliated. That affiliation is disclosed here so you can weigh it. It does not make me a treating physician for this article, no product or service is promoted on this page, and nothing here should be read as a treatment plan, a prognosis or a promise of any outcome.

This article is reviewed against the standards published in our editorial policy, and the limits of the medical information here are set out in our medical disclaimer. If you are in China and something feels urgent — jaundice, a rapidly risingALT, confusion, or bleeding — go to an emergency department rather than waiting for a scheduled review. If you are outside China and holding results from a Chinese hospital, bring the dated report and reference ranges to a hepatologist before starting anything.
