Probe selection criteria

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.
