How is carbon monoxide poisoning diagnosed?

Your healthcare provider can do a blood test soon after CO exposure to detect carbon monoxide poisoning. The test doesn’t show how severe the poisoning was or if you’ll have long-term health problems.

Your provider will figure out the best treatment for you based on:

  • How long you were exposed to the CO.
  • How concentrated (thick) the gas was.
  • Your overall health.
