she should also check out ICHIP insurance if in Illinois. They help give insurance to the uninsurable - http://www.chip.state.il.us/
many hospitals and medical groups and their labs groups have financial aid - like Northshore University HealthSystem. I think 2 different types - financial aid w/ regular docs/hospital appts and also via the clinic
she should start by talking w/ her doc that wants the tests
