Middleton's Maneuver: Sensitivity and Specificity

Introduction: None written. Excerpt from the entry in Splenomegaly:
The patient is asked to lie flat with his or her left fist under the left costovertebral angle. The examiner is positioned to the patient's left, facing the patient's feet. The fingers of both the examiner's hands are curled under the left costal margin, and the patient is asked to take a long, deep breath as the palpation of a descending spleen is sought.
