Helping You Understand Your FibroScan® Results

FibroScan is a specialized ultrasound machine for your liver. It measures fibrosis (scarring) and steatosis (fatty change) in your liver. Fatty change is when fat builds up in your liver cells. FibroScan can be used alone or with other tests (such as blood tests, imaging scans or biopsies) that also measure scarring or fatty change in your liver.

Your FibroScan report may look like this:

Your FibroScan Results
Date: __________ FibroScan steatosis result (CAP score): __________ decibels per meter (dB/m) - Steatosis grade: _________ FibroScan fibrosis result: __________ kilopascals (kPa) - Fibrosis score: _______________  
Your CAP score

Your CAP score is a measurement of fatty change in your liver. Your clinician will use your CAP score to find out your steatosis grade.

The CAP score is measured in decibels per meter (dB/m). It ranges from 100 to 400 dB/m. The table below shows ranges of CAP scores and the matching steatosis grade and amount of fatty change.

CAP Score Steatosis Grade Amount of Liver with Fatty Change
238 to 260 dB/m   S1   11 to 33%  
260 to 290 dB/m   S2   34 to 66%  
Higher than 290 dB/m   S3   67% or more  
Your fibrosis result

Your fibrosis result is a measurement of the amount of scarring in your liver. FibroScan measures scarring by measuring the stiffness of your liver.
The fibrosis result is measured in kilopascals (kPa) It’s normally between 2 and 6 kPa. The highest possible result is 75 kPa. Many people with liver disease(s) have a result that’s higher than the normal range.
Your clinician will use your FibroScan fibrosis result and your medical history to determine your fibrosis score.

Fibrosis score F0 to F1: No liver scarring or mild liver scarring

Fibrosis score F2: Moderate liver scarring

Fibrosis score F3: Severe liver scarring

Fibrosis score F4: Advanced liver scarring (cirrhosis)

Using your FibroScan fibrosis result to estimate your fibrosis score

The table below shows liver diseases, ranges of fibrosis results, and the matching fibrosis score. The ranges of fibrosis results in the table are estimates. This means that your actual fibrosis score (the score that your clinician tells you) may not match the fibrosis score in the table. If you have more than one liver disease, you may not be able to use the table.

To use the table, find the liver disease that you have on the left side of the table. Read across the row from left to right until you find the range that includes your fibrosis result. Then, look at the top of that column to see the fibrosis score.

  F0 to F1 F2 F3 F4
Hepatitis B 2 to 7 kPa   8 to 9 kPa   8 to 11kPa   18 kPa or higher  
Hepatitis C 2 to 7 kPa   8 to 9 kPa   9 to 14 kPa   14 kPa or higher  
HIV/HCV coinfection 2 to 7 kPa   7 to 11 kPa   11 to 14 kPa   14 kPa or higher  
Cholestatic disease 2 to 7 kPa   7 to 9 kPa   9 to 17 kPa   17 kPa or higher  
Nonalcoholic fatty liver disease (NAFLD or NASH) 2 to 7 kPa   7.5 to 10 kPa   10 to 14 kPa   14 kPa or higher  
Alcohol-related disease 2 to 7 kPa   7 to 11 kPa   11 to 19 kPa   19 kPa or higher  

Your fibrosis result may be overestimated (your liver may have less scarring than what your fibrosis result says) if you have:

Liver inflammation. This can be caused by a recent liver illness or drinking alcohol.

Benign (not cancerous) or cancerous tumors in your liver.

Liver congestion (when your liver is too full of blood or other fluids). This is usually caused by heart failure.

Your FibroScan results may also be less accurate if you have:

A body mass index (BMI) higher than 30 (obesity)

A buildup of fluid in your abdomen (ascites)

Too little bile flowing out of your liver (biliary obstruction)

Your clinician will talk with you about your results during your appointment. If you have questions, please call our office.
