What toxins can I get a blood test for, that health insurance will cover? I know that lead is usually covered, but what else?
As long as the test is medically necessary, it would generally be covered by health insurance. The test would need to be related to symptoms you were having, or be a screening for potential illness, such as high cholesterol.
The other factor would be that the test would have to be done by a covered provider. The provider isn’t necessarily on the plan’s “network”, but would need to be a licensed physician, nurse, etc. So for example, a Chinese medicine healer performing the test would not be covered.
