Since 1954, the NIH Clinical Center, the research hospital on the NIH campus in Bethesda, Maryland, has welcomed patients and healthy volunteers from around the world to participate in medical research studies.
Some of these studies compensate for participation. We process over 20,000 payment transactions a year to both patients and healthy volunteers.
We now offer three options of payments to research volunteers: Direct Deposit, U.S Debit Card and Digital Pay (Virtual). Read more about Payment Resources.
