• A person has chest pain and a heart attack is suspected, or after a heart attack to monitor ongoing heart damage;
• When someone has experienced physical trauma, such as crushing injuries or extensive burns;
• A person has symptoms associated with muscle injury, such as muscle pain or weakness; and
• When a person has nonspecific symptom – especially when taking a drug or after an exposure to a substance that has been linked to potential muscle damage.
