The National Living Donor Assistance Center (NLDAC), launched in 2007, provides reimbursement for travel and subsistence expenses for living organ donors to travel to the transplant center to donate an organ. The University of Kansas and the Mayo Clinic in Arizona, in partnership with the American Society of Transplant Surgeons (ASTS) and Arbor Research, operate NLDAC.

Many individuals may wish to become living donors for family or acquaintances, but lack the necessary resources to cover non-medical expenses not covered by insurance. The costs of being a donor can represent a substantial financial burden on the parties involved; for some, nonreimbursed expenses may make living donations impossible.

Approved living organ donors receive a controlled value card, which is like a credit card, to pay for approved transportation, food and lodging expenses up to $6,000. Donor and recipient household incomes are means tested at 300% of the federal poverty guidelines. Priority is given to individuals who cannot otherwise afford the expenses. The program provides an exception to this funding threshold for documented financial hardships.

The Arbor Research Collaborative for Health supports NLDAC through the management of the center's website, data warehousing and analysis, and participation in the senior research team.
