We don’t donate enough blood as a nation. And only 1 in 3 people who do donate blood do so more than once a year.
Everyone‘s favourite interest is themselves. And your blood is filled with lots of bespoke info about you.
Extracting genomic DNA from blood is 80% cheaper than it was 5 years ago.
Give people a small amount of personalised info every time they donate blood — to incentivise them to come back.
