Huelsen A(1), Fischer J(2), Hegarty J(3), Ashcroft A(4), Frampton CM(5), Barclay ML(6). Palpate the bottom margin of the liver for the texture of the liver, i.e. Soft/ firm/hard/nodular. Scratch Test. Several different techniques have been described for this exam. One is to place the diaphragm over the area of the liver and then scratch parallel to the costal margin until the sound intensity drops off marking the edge of the liver.

The Liver scratch test is a method medical professionals use in ascertaining the location and size of a patient's liver during a physical assessment. It is often used when other techniques, such as the hepatojugular reflux test either fail or are ineffective, most often due to abdominal distention or muscle tenseness. The Liver scratch test uses auscultation to detect the differences in sound transmission through the abdominal cavity over solid and hollow organs and spaces.[1]

After placing a stethoscope over the approximate location of a patient's liver, a medical professional will then scratch the skin of the patient's abdomen lightly, moving laterally along the liver border. When the liver is encountered, the scratching sound heard in the stethoscope will increase significantly. In this manner, the size and shape of a patient's liver can be ascertained.
