This week is Blood Donor Week, an annual celebration to thank the blood donors of Scotland.
From Monday 11 to Friday 15 June 2018 we're asking you to show your support by taking part in the #MissingType campaign.
#MissingType aims to raise awareness of the importance of blood groups, as not every blood type can help every patient: the missing A's, B's and O's signify missing A, B and O blood donors across the country.
Joining in is simple. Just download and print out one of our flashcards, fill in your name (or a message of support) missing out the A's, B's and O's, and email us a selfie to firstname.lastname@example.org
