It's because the preservatives in the bag intended to receive your blood only work correctly if they're in the right proportion. They're included presuming a full donation.
- ken 9y agoSo when the donation is aborted (e.g., the needle hits a valve or skin plug) and they only get part of a unit, but say the partial donation can still be used for research, how does that work? Do researchers not care if the blood is extra-anti-coagulated?
- wyldfire 9y agoLast time I gave a partial donation I was told it would be unused. It would be nice if they could deliver the blood to researchers but there might be challenges regarding the chain of custody, or donor history/privacy. Partial donations are probably rare enough not to try overcoming those challenges.
