Who Should Get a FibroScan? Gastroenterologist Explains Who May Need This Liver Test

A FibroScan is a non-invasive test that can help doctors assess the health of the liver without a biopsy. It measures liver stiffness, which can indicate the presence and severity of liver fibrosis, or scarring. Some FibroScan devices can also estimate liver fat.

But does everyone with fatty liver or abnormal liver tests need one? Not necessarily. A gastroenterologist may recommend a FibroScan when there is a reason to assess the risk of liver fibrosis or advanced liver disease.

What is a FibroScan?

FibroScan uses a technology called transient elastography to measure how stiff the liver is. Increased stiffness can be associated with fibrosis and cirrhosis.

Unlike a liver biopsy, it does not involve inserting a needle into the liver. It is generally quick and can be repeated when doctors need to monitor changes over time. European Association for the Study of the Liver (EASL) guidelines recognise transient elastography as one of the non-invasive methods used to assess liver fibrosis.

1. People With Fatty Liver

People diagnosed with metabolic dysfunction-associated steatotic liver disease (MASLD), previously commonly called non-alcoholic fatty liver disease, may be advised to undergo further assessment if there are concerns about liver fibrosis.

Fat in the liver does not automatically mean that significant scarring is present. A FibroScan can help doctors assess whether fibrosis may have developed.

This is particularly relevant in people who also have obesity, type 2 diabetes, high blood pressure, abnormal cholesterol, or other metabolic risk factors. The American Association for the Study of Liver Diseases has highlighted the need for earlier identification of liver fibrosis among people with cardiometabolic risk factors such as obesity, type 2 diabetes, and metabolic syndrome.

2. People With Persistently Abnormal Liver Enzymes

Raised levels of liver enzymes such as ALT and AST can have several causes. If these abnormalities persist, a doctor may investigate whether there is underlying chronic liver disease.

Depending on the person's history, blood tests, and test results, a FibroScan may be used to assess whether liver stiffness is increased.

However, an abnormal liver enzyme result alone does not mean that a person definitely needs a FibroScan. The decision depends on the overall clinical picture.

3. People With Chronic Hepatitis B or C

Chronic viral hepatitis can cause inflammation and progressive scarring of the liver. FibroScan can form part of the assessment of liver fibrosis in people with chronic viral hepatitis.

EASL guidance notes that transient elastography can be used to assess fibrosis in chronic hepatitis C, although results need to be interpreted alongside other clinical and laboratory information.

4. People With a History of Significant Alcohol Use

Long-term heavy alcohol consumption can damage the liver and may eventually lead to fibrosis or cirrhosis.

A gastroenterologist may recommend liver stiffness assessment when there is a history of significant alcohol exposure, particularly if there are abnormal liver tests, fatty liver, or other signs suggesting chronic liver damage.

5. People Who May Already Have Advanced Liver Disease

A FibroScan can be useful when doctors need to assess the likelihood of significant fibrosis or cirrhosis.

This is important because advanced fibrosis and cirrhosis are associated with a higher risk of complications. EASL notes that the presence and severity of fibrosis are important in determining the prognosis of chronic liver disease.

Do You Need a FibroScan Just Because You Have Fatty Liver?

Not always.

A common misconception is that everyone diagnosed with fatty liver should immediately have a FibroScan. In practice, doctors may first use medical history, blood tests, and non-invasive scores to assess the risk of significant fibrosis. Those at higher risk may then undergo elastography or another appropriate assessment.

This approach is important because non-invasive tests are designed to work together rather than as a replacement for clinical assessment. EASL recommends integrating blood-based tests, liver stiffness measurements, imaging, and clinical assessment according to the individual situation.

What Does the FibroScan Result Tell You?

The test primarily provides information about liver stiffness. A higher measurement can suggest a greater likelihood of fibrosis, but it does not by itself establish the exact cause or stage of liver disease.

Results can also be affected by factors such as inflammation, liver congestion, food intake, and certain other conditions. Therefore, the number should not be interpreted in isolation.

Is FibroScan a Replacement For A Liver Biopsy?

No. FibroScan has made liver assessment easier and less invasive, but it does not provide all the information that a biopsy can provide.

In some patients, particularly when test results are unclear, or another liver condition needs to be investigated, a doctor may still recommend additional tests such as SGOT test or, in selected cases, a liver biopsy. EASL stresses that non-invasive tests and invasive investigations need to be considered within the wider clinical context.

Final Word

A FibroScan is particularly useful for people who have known or suspected chronic liver disease and may be at risk of liver fibrosis. This includes some people with fatty liver, diabetes or other metabolic risk factors, chronic hepatitis, significant alcohol-related liver risk, persistently abnormal liver tests or suspected advanced liver disease.

However, it is not a routine test that everyone needs. A gastroenterologist can decide whether it is appropriate after considering the person's medical history, blood tests, ultrasound findings, and other risk factors.
