Your liver can look fine on the outside while quiet changes build in your liver inside. In the early stages, scarring and fat build-up may not cause pain, sickness, or a clear change in energy. So, some people choose a check that can spot early warning signs before feeling unwell. A scan focuses on stiffness and gives a clear starting point, then your clinician can explain what to do next.
Can Liver Scarring Start Without Symptoms?
Early liver scarring can start quietly. The liver does not have many pain nerves, so damage can progress without a warning sign you can easily recognise. You might notice vague changes like tiredness or poor sleep, though those signs can come from dozens of causes.
Risk tends to rise in people who drink more alcohol than their body can process, carry more weight, or live with type-2 diabetes. Some medicines can also affect the liver. A blood test can help, but it cannot always show how much scarring has formed.
Non-invasive scanning meanwhile helps a clinician pick up early fibrosis before it moves into advanced scarring.
How Does a Fibroscan Measure Liver Stiffness?
During a fibroscan, a clinician places a probe on the skin over the right side of your upper tummy. It sends a gentle vibration through the liver and tracks how fast a wave travels through the tissue. A faster wave points to stiffer tissue, which can link with fibrosis.
Using ultrasound technology, it doesn’t feel like a procedure. No needles go into the liver, no sedation is used, and most people finish their appointment quickly before getting on with their day.
What Does a CAP Score Indicate?
Your clinician can also estimate liver fat during the scan. Commonly reported as a CAP score, it reflects how ultrasound waves are reduced as they pass through the liver. Higher values can point to higher levels of fat in the tissue.
Fat build-up matters because it can appear alongside inflammation and fibrosis. In some people, fat is present without much scarring.
A CAP score can help your clinician frame a conversation about diet, alcohol, sleep, and activity. It can also help track change when lifestyle adjustments are made and then checked again later.
Which Health Concerns Lead to a Referral?
A clinician may suggest this test when blood tests highlight liver irritation, or when risk factors linked with MASLD are present. A referral can also follow a scan that suggests fat build-up, or after a period of heavier alcohol intake.
Your clinician can also use a fibroscan to monitor known liver disease. Repeat scans can show whether stiffness is stable, rising, or trending down, guiding how closely someone needs a follow-up.
Plenty of people feel well and still get a referral. That can happen after routine blood work, a medication review, or a broader check-up that flags risk to your liver.
How Should You Prepare For an Appointment?
Most clinics ask for you to have short fast before your appointment, since food can affect readings. Your appointment letter will tell you the timing. Loose clothing can help since the probe needs skin contact.
You will usually lie on your back with your right arm raised. The clinician applies gel and takes several readings. The machine then collects multiple measurements and uses the median value.
Talk to your clinician about anything that could affect accuracy. Some conditions and body shapes can make readings harder to capture, but your clinician can explain what that means for your result.

What Should You do After a Result?
Results make sense alongside a wider picture. Your clinician may talk through what the numbers suggest, then agree a plan for follow-up.
People may leave with reassurance and a date for a repeat scan. Others need extra blood work or imaging.
If your reading suggests fat build-up or early fibrosis, lifestyle changes can make a difference. The focus stays on consistent habits that fit your real week.
Pick changes that you can repeat. Your clinician may guide you based on your result. These ideas can also help:
- Remove all alcohol from your diet completely
- Add more vegetables and protein to your plates
- Choose slower-digesting carbs more frequently
- Aim for regular walking after eating
- Keep a steady sleep window
Change can feel easier when it is tracked.
What Can be Picked up Early by a Scan?
Changes that may not show up in daily life can still appear on a fibroscan.
You may expect damage to feel obvious. The liver can compensate for a long period, so symptoms can appear later than the changes themselves. That is where early scanning can help.
Scan results can also give language for a clinician to use. Instead of vague reassurance or vague concern, the conversation can be grounded in a measured reading.
Here are some signs to raise at your next appointment:
- Persistent tiredness that does not settle after rest
- Upper tummy discomfort on the right side
- Nausea that keeps returning
- Itchy skin without a clear cause
- Yellowing of the eyes or skin
- Dark urine or pale stools
These signs do not prove liver disease. They do signal that a review with a clinician makes sense.
Can it Reduce The Need For Liver Biopsy?
Liver biopsy involves taking a tissue sample with a needle. It can provide detailed information, though it also comes with risks and recovery time. A fibroscan offers a safer way to assess stiffness without entering the body.
No single test can answer every question. A clinician may still recommend a biopsy if results are unclear, if there is a need to confirm a diagnosis, or if treatment choices depend on specific findings.
In many cases, a non-invasive scan helps decide who needs further tests and who can be managed with monitoring and lifestyle change.
Can a Fibroscan be Wrong?
Results from a fibroscan give a useful estimate, though it is not perfect. Readings can change if the liver is inflamed at the time of the scan. A full stomach can affect the measurement too, which is why clinics tend to ask you to fast beforehand.
Body shape can also influence results. For some people, the machine can struggle to capture enough valid readings. Your clinician may repeat the scan, use a different probe, or suggest another test.
A single number does not replace clinical judgement. It helps most when your clinician can link it to your wider history and any other tests.
How Can You Track Progress Between Scans?
Baseline data can come from a fibroscan. Progress then comes from what you do between appointments.
Tracking helps because people’s memory is patchy. A quick log can show how alcohol intake, food choices, and activity look across a week. It can also highlight busy periods that push habits off course.
Your clinician may repeat the test after a set period to review any changes. A stable or improved result can reinforce your efforts. A higher reading can signal that a stronger plan is needed.
