Key Takeaways

• Minimal preparation is typically required before the procedure.
• The test is quick and generally well tolerated by patients.
• Understanding what to expect can help you feel more prepared for your appointment.

What Is a FibroScan and Why Might a FibroScan Doctor Recommend One?

A FibroScan is a specialised ultrasound-based test (transient elastography) used to measure liver stiffness and, in some cases, the amount of fat in the liver. Unlike a traditional liver biopsy, which involves removing a small tissue sample for analysis, a FibroScan assesses liver health without the need for an invasive procedure.

Your gastroenterologist or liver specialist may recommend a FibroScan if there are concerns about liver damage, inflammation or fatty liver disease. It is commonly used to evaluate conditions such as:

• Non-alcoholic fatty liver disease (NAFLD)
• Chronic hepatitis B or hepatitis C
• Alcohol-related liver disease
• Liver cirrhosis

The results can help determine whether scarring is present in the liver and how severe it may be. This information helps your doctor assess the extent of liver damage, monitor disease progression and guide appropriate management.

How Should You Prepare Before Your FibroScan Appointment?

Preparing for a FibroScan is usually simple, but following your doctor's instructions is important for obtaining accurate results.

In many cases, patients are advised not to eat for several hours before the test. Food intake can temporarily affect liver measurements, which is why fasting may be recommended. Your doctor or clinic will provide specific guidance based on your situation.

When attending your appointment, consider wearing comfortable clothing that allows easy access to the right side of your upper abdomen. Loose-fitting tops are often the most convenient choice. Any jewellery or piercings near the testing area should also be removed prior to the procedure.

Before the procedure, your FibroScan Doctor may ask about:

• Your medical history
• Current medications
• Previous liver conditions
• Recent symptoms or health changes

Inform your doctor if you are pregnant or have any significant implanted medical devices so they can determine whether any special precautions are required.

Many patients also worry about discomfort. Fortunately, a FibroScan does not involve injections, incisions or anaesthesia. Most people find the preparation process minimal compared to many other diagnostic tests.

What Happens During a FibroScan Test?

A FibroScan appointment is typically completed within 10 to 15 minutes, although the entire visit may take slightly longer depending on the clinic.

During the procedure, you will be asked to lie comfortably on your back with your right arm raised behind your head. This position helps provide better access to the liver.

The healthcare provider will apply a small amount of gel to the skin over the liver area and place a handheld probe against the skin. The probe sends painless vibrations and ultrasound waves through the liver tissue to measure stiffness and fat content.

As measurements are taken, you may feel a light tapping sensation on your skin. Most patients describe it as mild and easily tolerated.

The procedure is completely non-invasive and does not require any recovery time. You can remain awake and alert throughout the examination. Multiple measurements are usually taken to improve reliability and provide a more accurate assessment of liver stiffness and fat accumulation.

What Can You Expect After the FibroScan Is Complete?

Once the FibroScan is finished, you can immediately return to your normal daily activities. There are no restrictions on driving, working, eating or exercising unless your doctor advises otherwise.

Depending on the clinic, your results may be available on the same day or discussed during a follow-up appointment. Your FibroScan Doctor will explain what the measurements mean and whether there are signs of liver stiffness, fibrosis or excess fat accumulation.

It is important to remember that FibroScan results are only one part of your overall health assessment. Your doctor may also consider:

• Blood test results
• Medical history
• Imaging studies
• Current symptoms

If abnormalities are detected, your doctor may recommend lifestyle changes, ongoing monitoring, additional investigations or treatment tailored to your condition.

For many patients, the test provides reassurance that their liver is healthy. For others, it offers valuable information that allows potential problems to be identified and managed early.

Who May Benefit From a FibroScan?

A FibroScan may be recommended for individuals who are at risk of developing liver disease or require monitoring for an existing liver condition. Because the test can assess both liver stiffness and fat accumulation, it is a useful tool for detecting early signs of liver damage before symptoms become apparent.

You may benefit from a FibroScan if you:

• Have fatty liver disease (MASLD/NAFLD)
• Have chronic hepatitis B or hepatitis C
• Have alcohol-related liver disease
• Have obesity, type 2 diabetes or metabolic syndrome
• Have abnormal liver function test results
• Have a family history of liver disease
• Require monitoring for liver fibrosis or cirrhosis

A FibroScan may also be recommended as part of a routine liver health assessment for individuals with risk factors but no obvious symptoms. Since many liver conditions can progress silently, early detection allows for timely intervention and treatment where necessary.
