Phosphorylated Tau Levels in Donated Blood
This study is not testing a drug or therapy. Researchers are examining donated blood plasma samples to measure levels of a protein called phosphorylated tau-217, a biological marker linked to Alzheimer's risk. The goal is to find out whether some donated blood units contain unusually high levels of this protein, and whether that could matter for people who receive transfusions. The phase is unspecified, making this observational research, not a clinical intervention.
You may qualify if
- The plasma sample from donators.
You're excluded if
- None.
