Hepatitis B diagnosis and long-term treatment (Hepatitis B diagnosis and treatment)

What is hepatitis B testing and treatment?

Hepatitis B is an infection of the liver caused by the hepatitis B virus (HBV), which spreads through blood and some body fluids. Many adults clear it on their own, but some people, especially those infected at birth or in early childhood, develop a long-term (chronic) infection.

Diagnosis uses blood tests to confirm the infection, work out which phase it is in, and check whether the liver is inflamed or scarred. This tells your team whether you need treatment now or careful monitoring.

Treatment usually means antiviral tablets that suppress the virus and protect the liver. For most people these control the infection rather than curing it, and are often taken long-term or for life. Some people are offered a course of injections (peginterferon) instead.

The aims of care are to keep the virus under control, prevent or slow liver damage, lower the risk of liver cancer, and stop the virus spreading to others. This guide explains what to expect and what to ask. It is general information, not personal medical advice; your liver specialist will tailor your plan.

Types, options & approaches

There may be different ways to do this. The right approach depends on the clinical question and your circumstances.

Antiviral tablets vs peginterferon

Which option suits you depends on the phase of infection, your liver and other health factors. Your specialist will advise.

Preparing for your treatment

• Bring details of how the infection may have been caught and any past results, if you have them.
• List all your medicines and supplements, as some interact with antivirals or affect the liver.
• Tell your clinician if you are pregnant, might become pregnant, or are breastfeeding, as this changes the plan.
• Mention any kidney or bone problems, since some antivirals are monitored for these.
• Ask whether your close contacts and household should be tested and vaccinated.
• Ask whether you need a fibrosis scan and liver-cancer surveillance, and how often.
• Avoid alcohol or keep it to a minimum, as it adds to liver strain.

What happens

Diagnosis starts with blood tests. These confirm hepatitis B (using the surface antigen, HBsAg), and further tests work out the phase of infection and how active the virus is, including the e-antigen and the viral load (HBV DNA). Tests of liver function, and a fibrosis (liver stiffness) scan, show whether the liver is inflamed or scarred.

Based on these, your specialist decides whether to treat now or to monitor. Treatment is often recommended if the viral load is high, liver tests are persistently raised, there is cirrhosis, or during pregnancy when virus levels are high.

If you start antiviral tablets, you take one a day and have regular blood tests to check they are working and to watch your kidneys and bones. If monitoring rather than treating, you have regular check-ups, fibrosis checks and, for some people, six-monthly liver-cancer surveillance scans. Vaccination of close contacts is arranged.

Is this treatment right for me?

A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.

Before you decide

Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.

The most important point is that chronic hepatitis B usually cannot be fully cured, so stopping tablets without specialist advice can trigger a dangerous flare. Ask how long you will need treatment, how your kidneys and bones will be monitored, and whether you need liver-cancer surveillance.

Published figures to discuss

How hepatitis B behaves, and how well treatment works, varies with the phase of infection, the viral load, the degree of liver scarring and other factors. The pointers below are broad and source-based, not predictions for any individual.

These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.

What happens afterwards

There is no physical recovery from a blood test or daily tablet. "Afterwards" is really about long-term monitoring and what your results mean for your liver and the people around you.

• Most people feel no different on antiviral tablets
• Viral load usually falls over the first months of treatment
• Liver blood tests often improve but are still monitored
• Needing ongoing appointments rather than a one-off 'cure'

Aftercare

• Take antiviral tablets every day as prescribed; do not stop without specialist advice.
• Attend all monitoring appointments, blood tests and scans, even when you feel well.
• Make sure close contacts and household members are tested and vaccinated if needed.
• Keep alcohol low and look after general liver health.
• Tell any clinician treating you that you have hepatitis B, especially before strong immune-suppressing drugs or chemotherapy.
• If pregnant or planning pregnancy, discuss steps to protect the baby.
• Know who to contact if you develop jaundice or feel unwell.

• Antiviral prescription and repeat supply arranged
• Monitoring schedule written down (viral load, liver and kidney tests)
• Liver-cancer surveillance arranged if recommended
• Close contacts offered testing and vaccination
• Plan in place if pregnant or planning pregnancy
• Out-of-hours contact saved in case of warning signs

⚠ Get urgent help if…

• Yellowing of the skin or eyes (jaundice) that is new or worsening
• Dark urine, pale stools, or severe tummy pain
• Marked tiredness, confusion or drowsiness
• Vomiting blood or passing black, tarry stools - call 999
• Swelling of the tummy or legs
• Severe low mood or thoughts of self-harm while on interferon - seek urgent help

Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.

General guidance — it doesn't replace the specific advice your specialist gives you.

Results & realistic expectations

A good result on treatment usually means the virus is strongly suppressed (a low or undetectable viral load) and liver tests are stable, lowering the long-term risk of cirrhosis and liver cancer. With peginterferon, a smaller number of people reach a "functional cure" and may be able to stop treatment.

What treatment usually cannot do is completely clear the virus, because it can hide in liver cells. That is why monitoring, and for some people surveillance for liver cancer, continues even when results look good.

With effective, sustained antiviral treatment many people with chronic hepatitis B live a normal lifespan with a well-controlled liver. The benefit lasts as long as the virus stays suppressed, which is why treatment is often long-term. Results are reviewed regularly, and the plan may change over the years.

Related tests, treatments or support

Hepatitis B care is often coordinated with vaccination against hepatitis A, checks for hepatitis C and HIV, and management of other liver risks such as alcohol or fatty liver. If you have cirrhosis, surveillance and management of complications are combined with antiviral treatment.

Follow-up & long-term care

Follow-up is long-term. People on treatment have regular blood tests to confirm the virus stays suppressed and to monitor kidneys and bones. Those not on treatment are reviewed regularly, often every 6-12 months, with fibrosis checks and, for some, six-monthly liver-cancer surveillance.

• Daily antiviral tablets, often long-term or lifelong
• Regular viral load, liver and (for tenofovir) kidney and bone monitoring
• Fibrosis assessment at set intervals
• Six-monthly liver-cancer surveillance for those at higher risk
• Keeping close contacts vaccinated and protected
• Review before any strong immune-suppressing treatment for other conditions

Repeat, follow-on and what comes next

• Treatment decisions are reviewed over time as the phase of infection and liver tests change.
• If one antiviral is not tolerated or is unsuitable, another can usually be used.
• Some people who are monitored will later need treatment, and a few on peginterferon may stop after a functional cure.

Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.

What good aftercare looks like

• A clear monitoring schedule for the virus, liver, kidneys and bones.
• Liver-cancer surveillance arranged and explained for those at higher risk.
• A named contact and clear advice on when to seek urgent help.
• Testing and vaccination organised for partners, household and family.
• Coordination with maternity care in pregnancy to protect the baby.

What affects the cost

Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:

• Initial blood tests, fibrosis scan and specialist consultation
• Whether you need treatment or monitoring, and how often you are reviewed
• The medicine used (long-term antiviral tablets versus a course of injections)
• Regular monitoring of viral load, liver, kidneys and bones
• Liver-cancer surveillance scans if recommended
• Testing and vaccinating close contacts

• The specialist's consultation and follow-up fees
• Costs of diagnostic and monitoring blood tests, and how often
• The cost of antiviral medicines and who prescribes repeats
• Whether fibrosis scans and liver-cancer surveillance are included
• Whether testing and vaccinating contacts is covered
• What happens, and who pays, if a liver flare or complication occurs

On the NHS? Hepatitis B testing, treatment and monitoring are available on the NHS; private care is mainly used for speed, choice of clinician or a second opinion.

You're entitled to your total cost in writing — including reports, follow-up and what happens if the result is inconclusive — before you decide.

Consent traps and marketing red flags

These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.

Choosing a specialist safely

• Check the specialist is on the GMC Specialist Register for this area.
• Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
• You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
• Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
• You're entitled to your total cost in writing — including any follow-up — before you decide.
