Donating Blood: Giving the Gift of LifeEn Español (Spanish Version)
Did you know that many Americans will need blood or a blood product at some point in their lifetime? But sadly, only a small percentage of healthy Americans who are eligible to donate blood actually do donate each year.
In general, to give blood, you must:
- Be healthy
- Be at least 17 years old
- Weigh a minimum of 110 pounds
Giving blood may seem scary, but it is a simple process. By knowing what to expect, you can take the mystery—and the fear—out of giving blood.
When you arrive at the blood drive or center, you will go through an interview. The interview will be private and confidential.
You will need to provide:
- Date of birth
- Valid form of identification
The Red Cross will do a mini-physical exam that includes checking:
- Body temperature
- Blood pressure and pulse
- A drop of your blood to be sure you have enough red blood cells to donate safely
- You will be asked about your past and present health and lifestyle, and the Red Cross will answer any questions you may have. Depending on your answers, you may be deferred from donating, either temporarily or permanently.
- If you are allergic to tape, or natural latex rubber, tell the interviewer so that the donation staff can substitute other materials.
You will be given a form so you can let the Red Cross know,
privately, if your blood is safe to give to another person.
Tell the interviewer if you:
- Are not feeling well
- Are running a fever
- Have traveled out of the country lately, especially to less developed countries
- If at any time you decide that you should not give blood, you may walk away.
Now you are ready to give blood. The actual donation will take about 8-10 minutes.
- The Red Cross staff member will cleanse an area of the arm. All of the supplies, including the needle, are sterile and are used only once—for you.
- When the actual donation starts, you may feel a brief "sting" from the needle.
- You will have given about a pint of blood when finished. Your body will replace the plasma (liquid part) in hours and the cells in a few weeks.
When you are finished, you will be given a form with:
- Donation instructions
- A number to call if you decide, after you leave the donation center, that your blood may not be safe to give to another person
- When you are finished, you will be taken into a room and given some snacks (usually juice and cookies) for energy.
Although most people feel fine before and after donating blood, a small number of people may experience:
- Upset stomach
- Faint or dizzy feeling
- Black and blue mark, redness, or pain where the needle was inserted
- Very rarely, a person may faint, have muscle spasms, and/or suffer nerve damage
Examples of situations where you should not give blood include but are not limited to:
- Had a tattoo within the last 12 months in a state that does not regulate tattoo facilities
- Recently received certain vaccinations—Check with the Red Cross Center for specifics
