Donating Blood: The Process

Whether it’s the needles, the amount of time, or even the blood itself, less than 10% of the population eligible to donate blood does so. Even though many feel uncomfortable donating blood, there are almost no risks, except a minor pinch from the needle at the beginning of the donation.

Donated blood is given to a variety of people with different needs—from cancer patients to persons having surgeries and transplants to accident victims.

Feel more at ease and more open to giving blood by learning a little bit more about blood donation process.

Before

  • Eat healthy foods about four hours before donating, staying away from greasy foods.
  • Hydrate—drink about 16 ounces of water or nonalcoholic juices.
  • Sleep well the night before.
  • Don’t take aspirin for two days beforehand if you’re donating platelets.
  • Bring a photo ID, such as driver's license or school ID, and a list of any medications you currently take.

During

  • Wear a short-sleeved shirt or one that can have its sleeves easily rolled above the elbow. 
  • Stay calm, and remember there are almost no risks to you.
  • Tell the technician if you have an arm preference.
  • Right after donating, eat and drink the provided snacks and beverages. 

After

  • Continue to drink fluids, but do not drink alcohol for 24 hours.
  • Avoid doing intense exercises or heavy weight lifting for that day.
  • Within the following hour, take off the wrap bandage, if one was put on your arm. However, leave the strip bandage on for the next several hours.
  • Use soap and water to clean your arm near the bandages—this will help to avoid a skin rash.
  • If you begin to bleed from the needle prick, then put pressure on it and hold your arm straight up until it stops bleeding.
  • Sit or lie down if you start feeling dizzy or lightheaded.
