Question

How long to keep band on after donating blood?

Answer 1

If you are referring to the band-aid  ( or most places now use medical elastic tape so it doesn't cause as much irritation or tear the skin when taking it off, plus it helps in clotting) The answer is 4-5 hours. If bleeding or bruising occurs within 24 hours under the skin, apply cold packs to the area indirectly to the skin with arm elevated.Usually 10 mins on 15-2- mins off
