I donated blood on Saturday. It's the first time I've done so since I was 18. That's because I've been lazy and thought it would take a while to schedule.
Nope.
At least here in North Texas,
Carter BloodCare has many locations open 6 days a week (some are closed Tues and some are closed Sun). I was able to register and schedule online in about 10 minutes the night before, do my questionnaire the next morning in about 10 minutes while eating breakfast, and donate, which took a total of an hour including drive time, prepping, and refreshing, all before my hearty lunch the next day.
I'm type O-positive.
Whatever your type, your blood is in demand. Go donate.
I'm now putting it on my calendar for every two months (the most often I can donate if I give whole blood). I opted for whole blood because it's the best for giving the most amount of overall material when you don't know your type, which I didn't before I walked in, and you donate regularly, which I now plan to do. If I were O-negative, I would probably give double reds (once every 4 months max) to decrease how often I would donate. However, now that I know I'm not O-neg, I think whole blood will do the most good.
