Tests and procedures used to diagnose a ruptured spleen include:

  • Physical exam. Your doctor will use his or her hands to place pressure on your abdomen to determine the size of your spleen and whether you're experiencing any abdominal tenderness.
  • Blood tests. Your doctor will order blood tests to evaluate factors such as platelet count and how well your blood clots.
  • Checking for blood in your abdominal cavity. Your doctor may use an ultrasound test to do this. Or he or she may use a needle to draw a sample of fluid from your abdomen. If the sample reveals blood in your abdomen, you may be referred for emergency treatment.
  • Imaging tests of your abdomen. If your diagnosis isn't clear, your doctor may recommend an abdominal CT scan or another imaging test to identify or rule out other possible causes of your symptoms.
