How do you prepare for Blood Donation?

Before your blood donation:

  • Before you donate blood, make sure you get plenty of rest the night before.
  • Eat a healthy meal and drink plenty of water. Avoid fatty foods.
  • Check to see if any medications you’re taking or have recently taken will prevent you from donating. For example, if you’re a platelet donor, you can’t take aspirin for two days before donating. Before you stop taking any medications, talk to your doctor.

Before the donation, a brief physical exam will also be performed, including checking your blood pressure, pulse, and temperature. A small blood sample is taken from a finger prick and used to determine whether your blood is oxygen-carrying (hemoglobin level). You can donate blood if your hemoglobin level is normal, and you meet all other screening requirements.

You sit in an observation area after donating for 15 min. We advise you to rest and eat a light snack. Following your blood donation, you should:

  • Drink plenty of water.
  • For about five hours, avoid strenuous physical activity or heavy lifting.
  • If you’re dizzy, lie down with your feet raised until the sensation passes.
  • For the next five hours, keep your bandage on and dry.
  • If bleeding occurs after removing the bandage, apply pressure to the wound and raise your arm until it stops bleeding.
