The evaluation of a contusion begins with a medical history and physical examination.

Physical findings in someone with a contusion may include:

• Bruising
• Localized swelling
• Tenderness of the skin
• No tenderness of the bone or other deep structures
• Normal nerve and muscle function

Tests are not necessary to evaluate minor contusions. X-rays may used to look for fractured bones.

Tests that may be used to evaluate a severe bruise to the chest or abdomen include:

• Cardiac enzymes blood tests
• Urinalysis
• Chest x-ray
• Complete blood count
• CT scanning of the abdomen:
• An excellent test for excluding internal injury
• CT scanning of the chest
• EKG
• Ultrasound of the abdomen
