 | | Direct tenderness and rebound tenderness in the right lower quadrant, localized pain on cough, low-grade fever (rectal temperature 37.7 to 38.3° C [100 to 101° F]), and leukocytosis (12,000 to 15,000/µL) characterize appendicitis. |
 | | Classic right lower quadrant tenderness is located at McBurney's point (junction of the middle and outer thirds of the line joining the umbilicus to the anterior superior spine). |
 | | Tenderness may be diffuse or noted only on rectal or pelvic examination; in rare instances, tenderness is absent and abdominal pain, persistent fever, and leukocytosis are the only signs. |
