What To Expect During A FibroScan® Exam

What is FibroScan?

FibroScan is a proven technology used for non-invasive examinations of your liver. FDA cleared and clinically validated by over 2,000 peer-reviewed publications, FibroScan works by emitting a small pulse of energy, called a shear wave, which will feel like a light tap on your skin. FibroScan calculates the speed of this energy as it travels through your liver and translates that speed with two scores that your care provider will use to determine the overall health of your liver. The first score is a measure of your livers stiffness, the second score approximates liver fat. The combination of these scores gives your health care provider a better understanding of your livers overall health and how it changes over time with lifestyle or medical intervention.


Is it painful? No.

FibroScan examinations are painless, quick, and easy. During measurement, you will feel a slight vibration on the skin at the tip of the probe.

What Will The FibroScan Examination Be Like?

You will lie on your back, with your right leg crossed over your left leg and with your right arm raised behind your head. This is to allow easy exposure to the intercostal spaces (spaces between your ribs) for the probe to effectively scan your liver. Your healthcare provider will apply a water-based gel to the skin and then place the probe on the right side of your ribcage. Your healthcare provider will quickly produce 10 measurements during the FibroScan examination. These measurements will be used to establish an overall stiffness score.

FibroScan probes are adapted to fit most body-types and to all ages, from pediatric to adults. FibroScan examinations can take as little as ten minutes to complete.

How Should I Prepare For My FibroScan Examination?

It is important to have your FibroScan examination on an empty stomach, so don’t eat anything for at least 3 hours before your examination 1,2. We also recommend you wear comfortable clothes that will allow your healthcare provider to expose the right side of your rib.

Exam Contraindications

It is important to tell your healthcare provider if you are pregnant, or if you have any active implantable electronic devices, such as pacemakers, defibrillators, or pumps. FibroScan should not be used if you are pregnant or have any implantable electronic devices.
