Oh shoot I was worried a bunch spoiled and was going to weep for the loss but it sounds like it’s just a logistics problem. 😮‍💨

Reminder that even if you have O-positive (O-negative is the universal donor), O+ is still very useful! Negative blood types in general are fairly rare, and O+ can give to all other positive blood types. This means that blood can be used for most patients who they have time to type and crossmatch, and the only time they really don’t have time for that is traumas like car crashes and gunshots (so obviously they need as much of the O-negative as possible too). Unless they’re a negative blood type, all the anemics, the scheduled surgeries, and childbirth where the person can be typed and crossmatched in advance, they can often use the O+. Using the O+ for scheduled infusions means they can save that rarer O- (that might otherwise get used if no other match was available) for the emergencies where they need it most!
