Liver fibroscan
NCH gastroenterologists use FibroScan, a noninvasive ultrasound-based test, to measure liver stiffness and fat content — helping diagnose and monitor liver fibrosis and fatty liver disease without a biopsy.
What Is a Liver Fibroscan?
A Liver Fibroscan is a noninvasive test that uses a technology called transient elastography to measure the stiffness of your liver and the amount of fat it contains. During the test, a technician places a handheld probe on the skin over the right side of your abdomen, between the ribs. The probe sends painless, low-frequency vibrations into the liver and measures how quickly the resulting wave travels through the tissue.
A stiffer liver causes the wave to travel faster, which can indicate scarring, known as fibrosis. The same test also calculates a Controlled Attenuation Parameter (CAP) score, which reflects how much fat has built up in the liver — a marker of fatty liver disease.
Because Fibroscan requires no needles, incisions, or sedation, it offers a fast, comfortable alternative to liver biopsy for many patients being evaluated or monitored for chronic liver disease.
Why Is a Liver Fibroscan Performed?
Your gastroenterologist may recommend a Fibroscan to evaluate or monitor a range of chronic liver conditions.
Risk Factors for Fatty Liver Disease
Obesity, type 2 diabetes, or high cholesterol that raise the risk of NAFLD/NASH.
Chronic Hepatitis B or C
Assessing liver scarring related to viral hepatitis.
Long-Term Heavy Alcohol Use
Evaluating alcohol-related liver damage.
Abnormal Liver Function Tests
Known Liver Disease
Treatment Monitoring
Not every patient with liver risk factors needs a Fibroscan right away. Your gastroenterologist will review your labs, imaging, and medical history to determine whether Fibroscan, another test, or a change in management is the right next step for you.
Your Procedure Journey
From referral through results, here’s what to expect at each stage.
Consultation & Referral
Review of risk factors, symptoms, and prior lab or imaging results.
Preparation
A brief fasting period before your appointment.
Day of Test
Immediate Results
Liver stiffness and fat content (CAP) scores generated on the spot.
Results & Follow-Up
Your physician reviews the results alongside your labs and history.
No sedation is used for this test, so you do not need to arrange a driver and can return to your normal activities immediately afterward.
Is This the Right Test for You?
Liver Fibroscan and liver biopsy both help assess liver fibrosis, but differ significantly in invasiveness and recovery.
| Liver Fibroscan | Liver Biopsy | |
|---|---|---|
| Method | External probe on the skin measures liver stiffness with sound waves | A needle is inserted through the skin to collect a tissue sample |
| Invasiveness | Noninvasive — no needles or incisions | Invasive — requires a needle puncture into the liver |
| Sedation | Not required | Often requires local anesthesia and sometimes sedation |
| Recovery | None — resume normal activity immediately | Monitoring period required; activity restrictions for a period afterward |
Risks & Safety
Fibroscan is a low-risk, noninvasive test. There are no significant risks associated with the test itself.
No Procedural Risks
Since no needles, incisions, or sedation are used, there is no meaningful procedural risk.
Accuracy Can Vary
Results may be less reliable in patients with severe obesity, ascites (fluid in the abdomen), or narrow rib spacing.
One Part of the Picture
Fibroscan results are always interpreted together with your labs, imaging, and clinical history — not on their own.

Frequently Asked Questions
What is a liver Fibroscan?
A liver Fibroscan is a noninvasive ultrasound-based test that measures liver stiffness and fat content to help diagnose and monitor liver fibrosis and fatty liver disease, without the need for a biopsy.
Is a Fibroscan painful?
No. Most patients feel only a light tapping or vibration sensation as the probe sends painless pulses through the skin. No needles or incisions are involved.
Do I need to prepare for a Fibroscan?
Preparation is minimal — typically fasting for about 3 hours beforehand, since eating can temporarily affect the results. Your physician will confirm any specific instructions.
How long does the test take?
The test itself usually takes about 10 to 15 minutes, and results are generated immediately.
Do I need sedation or a driver?
No. Fibroscan does not require sedation, so you can drive yourself and return to normal activities right after the test.
What do my Fibroscan results mean?
Fibroscan generates two scores: a liver stiffness measurement (related to scarring, or fibrosis) and a CAP score (related to fat content, or steatosis). Your physician will interpret these results alongside your labs and medical history.
How is Fibroscan different from a liver biopsy?
Fibroscan is noninvasive and uses an external probe, while a liver biopsy requires a needle to collect a tissue sample. Fibroscan involves no incisions, sedation, or recovery time.
How often should I get retested?
This depends on your specific liver condition and risk factors. Some patients are monitored yearly, while others are tested more or less frequently based on their physician’s recommendation.
