The aRMOR System Blood Donor Verification Study is being conducted by Armor Medical Inc.

The purpose of this study is to learn how well the aRMOR System works during normal blood donation. The aRMOR System is a research device that uses light-based sensors placed on the skin to study body changes that occur when blood is lost. The aRMOR System has not been approved by the U.S. Food and Drug Administration (FDA).

Participation in this research study is completely voluntary. Choosing not to participate, or deciding to withdraw later, will not affect:

• Your eligibility to donate blood

• Future donation opportunities

• Medical care

• Employment

• Insurance benefits

• Any other benefits to which you are entitled

Blood donor eligibility is determined solely by ImpactLife according to its standard donor eligibility procedures. Participation in this research study does not change your blood donation or donor care, and the study device will not be used to make medical decisions.

If you submit the interest form on this website, a member of the study team may contact you to discuss the study and answer your questions.
