Diagnosis

Treatment is likely to start right away for anyone brought to an emergency room with suspected carbon monoxide poisoning. To confirm the diagnosis, the health care team might test a blood sample for carbon monoxide. This test should be done as soon as possible after removing the person from the suspected exposure environment. But the test shouldn't delay treatment.
