Diagnosing appendicitis can be tricky. Symptoms are often unclear or similar to those of other illnesses, including gallbladder problems, bladder or urinary tract infection, Crohn’s disease, gastritis, kidney stones, intestinal infection, and ovary problems.
These tests can help diagnose appendicitis:
Examination of your abdomen to look for inflammation
Urine (pee) test to rule out a urinary tract infection
Rectal exam
Blood test to see whether your body is fighting an infection
CT scans
Ultrasound
