How to Perform

With the patient supine, percuss the abdomen directly on skin from the umbilical region toward each flank and identify where tympany changes to dullness. Ask the patient to roll onto one side, wait briefly, then percuss the now-upper flank again. The test is positive if the boundary of dullness shifts toward the dependent side, causing the previously dull upper flank to become tympanitic.
