Recommendations for cleaning and disinfecting
FibroScan® probes and machine

Information provided on this webpage is a synopsis of the cleaning and disinfecting protocols described in your user manual. 



Always refer to the recommendations present in the user guide.

It is essential to follow specific local infection control protocols. Information provided on this website does not supersede the local infection control protocols. 


  • System: keyboard, screen, handles, probe holders
  • FibroScan®(VCTE™) probes
  • Ultrasound localization probe

Cleaning the device and probes

Prior cleaning is necessary to ensure effective disinfection

Clean using a soft cloth soaked in purified or soapy water

Wipe down with a soft cloth dampened with water

Dry carefully with a clean, soft and absorbent cloth 

Probe Disinfection

The probes must be cleaned and disinfected between each examination

Probe disinfection agents 

Disinfectant agents compatible with the probes were cross-referenced with the U.S. Environmental Protection Agency (EPA) List N (products that meet EPA’s criteria for use against SARS-CoV-2). In addition, we reviewed the cleaning agent manufacturer claims effectiveness against SARS-CoV-2.

Probe disinfection protocol

It is not necessary to switch off the device before cleaning and disinfecting the probe. 

Surfaces of the probe must be cleaned and disinfected strictly in the order described below.

Point the probe and transducer downwards.

Remove any remaining traces of gel with a soft cloth.

Clean the surfaces with a soft cloth or a wipe that has been dampened with the recommended cleaning product.
Note: if necessary, wipe down the surfaces with a soft cloth dampened with water.

Dry the probe with a soft, dry cloth.

Wipe the surfaces using a soft cloth or a wipe soaked in the recommended disinfectant solution.

Dry the probe with a soft, dry cloth.

Examine the transducer and probe cable for any damage such as cracks, breakage, or liquid leakage.

System disinfection
(keyboard, screen, handles, probe holders)

Currently, no disinfecting product or protocol has been tested on the FibroScan® system. Please refer to the cleaning section.
