insurance

No - not ethical.

Do you mean not run tests based on the patient's insurance, or based on their lack of insurance? In our office, we have a large number of indigent patients who need labwork or other tests, but cannot afford to have these done. We explain the need for the tests to be sure the patient understands the need for them, and we get them to sign a statement that they are choosing not to have labwork or tests even though these procedures are indicated for the treatment they are receiving.
