FibroScan® procedure for users

Find the key recommendations to run a liver examination with FibroScan®


Pre examination requirements

Patient shall be fasting for at least 3 hours and can take clear fluids only.1,2,3

Patient shall be lying on the examination bed for 5 minutes before the examination for the body to rest.

Operator shall be duly trained and certified by Echosens or its local representative. 

Device probes shall be calibrated.

Examination room set-up


  • Facing screen
  • On a height adjustable stool 




  • Lying flat on the examination bed
  • Right arm under the head
  • Banana shaped position 

Probe selection criteria with or without SmartExam

Ensure that the probe used corresponds to the patient’s body type:

  • To choose between the M or XL probe on adults, follow the automatic probe selection tool displayed in real time, based on the Probe to Liver Capsule Distance (PCD), and not on the patient’s BMI.
  • For children, probe selection criteria are based on thoracic perimeter (TP).


Warning: selecting XL probe only when M probe examination fails is not correct. Follow the automated probe advice.

Examination reliability criteria


  • At least 10 measurements at the same spot shall be performed with one single probe.
  • Liver stiffness IQR/Median ratio (%) shall remain ≤30% when final median stiffness result exceeds 7.1 kPa.4 



  • At least 10 measurements at the same spot shall be performed with one single probe.
  • No recommendations on IQR.

No, FibroScan® can be performed on every single patient. Examinations on pregnant women and patients with active implantable medical devices (pacemaker, defibrillator…) are not contraindicated.

Contraindications have been lifted since April 2016 in Europe, and subsequently in all other countries (including the United States since March 2023), except in Japan.

Probes are calibrated by Echosens support. All you need to know about probe calibration is available in the calibration FAQ.

The Interpretation Guide and cut-offs are on myFibroScan (app and website).

Peer-reviewed articles used for the cut-off are available in our Clinical Library.

Training and certification by Echosens or its local representatives is prerequisite for every FibroScan® user.

Connect with your local representative or contact us directly through the contact page available on this website.

There are many clinical studies available for reference in our clinical library.

  • For methotrexate, filter your search by selecting Etiology = “Drug induced liver injury (DILI)”.
  • For primary biliary cirrhosis and primary sclerosing cholangitis, filter your search by selecting Etiology = “Cholestatic disease”.
  • For haemochromatosis, filter your search by selecting aetiology = “Other”.

Products in the FibroScan® range are Class IIa medical devices as defined by Directive 93/42/EEC (EC 0459). These devices are designed for use in a medical practice in order to measure liver stiffness and ultrasound attenuation in patients with liver disease. Examinations with FibroScan® device shall be performed by an operator who has been certified by the manufacturer or its approved local representative. Operators are expressly recommended to carefully read the instructions given in the user manual and on the labelling of these products. Check cost defrayal conditions with paying bodies.
