A doctor will diagnose acetaminophen overdose with the following methods:

• History: The doctor will attempt to determine the time and amount of acetaminophen taken. Having access to all medication bottles that the person may have taken will help the doctor to determine the maximum amount taken.
• Physical: The doctor will look for signs and symptoms of acetaminophen poisoning. These may include jaundice (yellow skin), abdominal pain, vomiting, and other signs and symptoms.
• Laboratory tests: A blood level of acetaminophen will aid in determining if a toxic dose was taken. The doctor may order more than one blood level of acetaminophen, and test for other drugs taken. In addition, the doctor may order other blood and urine tests as needed.
