@cowguy – I have been through the donor process at Mayo. Many preliminary tests can be completed locally before the testing AT Mayo. Some of your travel expenses may be covered by the recipient's insurance. You should also check with NLDAC – National Living Donor Assistance Center. Talk to the Mayo transplant center about application for reimbursement of your travel expenses through NLDAC. If you can get this approved before you have to travel, they may be able to cover travel, lost wages, and dependent care expenses related to your evaluation trip, transplant, and follow-up visits. See http://www.livingdonorassistance.org for more information and be sure to ask the folks at Mayo!
