The : The best way to find thorough testing in your area is to contact your local poison center. They will be able to direct you to a toxicologist who can guide you in the right direction.

Carbon : Carbon monoxide poisoning -- whether acute or chronic -- is determined by measuring your carboxyhemoglobin levels. In cases of overexposure, your carboxyhemoglobin level will be elevated, but it will only remain high as long as you continue to be exposed to carbon monoxide. It is very difficult to document carbon monoxide poisoning (or exposure to natural gas leaks) two years after exposure ceased. There have been scattered reports of chronic, low-level carbon monoxide exposure leading to permanent memory loss, tremors, or learning disorders, but it isn't clear if such exposures cause permanent neurologic damage in all people. If you are having persistent symptoms you believe are related to carbon monoxide exposure between 1999 and 2009, a neurologist might be able to sort things out. Sometimes a brain MRI reveals characteristic changes in people who have experienced chronic carbon monoxide exposure. I hope that helps!
