I gave blood last week on the spur of the moment because a donation bus happened to be parked outside the dojo when I went to taekwondo class on Tuesday morning. Amazingly, my blood iron was high enough on the fingerprick test for them to let me donate--usually it is borderline to too low since I don't eat much red meat, so I take iron pills for a week or so in advance if I have a donation scheduled. Since I am a universal donor (type O negative) I at least try to donate every chance I get, and this time it all worked out.
Anyway, I gave the blood without incident, walked away, and didn't think any more of it till just now.
Five minutes ago, I got a text from the blood bank, telling me that my unit of blood had just been used and at which hospital! That's a new thing...I've never seen it before. Hope it made a difference for whomever received it.
