How often do I have to give a blood sample?

The ADNI Blood Biomarker Study is no longer accepting new participants. To find out about other research opportunities, please join the Brain Health Registry: https://www.brainhealthregistry.org/. We are here to help, so please let us know if you need it. You can always email the study team at info@adni4.org or call one of our staff at 1-888-299-ADNI (2364).

We may ask you to provide another blood sample in the future. We may reach out to you every 2 years to ask you to go to Quest for another blood draw. For each blood draw you will be compensated $70 in eGift Card(s).
