How much does it cost to have tests done at an ADNI clinical site (such as a blood test, MRI scan, PET scan, etc.)?

Every test that is completed related to your participation in the ADNI4 study will be available to you free of charge. If you are invited to the ADNI In-Clinic study, all tests related to the study are done for free. For example, if you have an MRI and/or PET scan as an ADNI participant, there is no cost to you. You may receive payment for your time and for completing those tests.
