Blood Donation FAQs
What if I have other questions?
The Community Blood Center is happy to answer any questions you may have about donation. Please call 1-888-59-BLOOD.
Is it safe to give blood?
Yes. Donating blood is safe. The supplies used to collect your blood are sterile and only used once. You cannot get HIV or any other infectious disease from donating blood.
How much blood do you take?
One pint. Most people have 10-12 pints of blood in their bodies, and it starts regenerting immediately.
Will I feel sick afterwards?
Most donors have no ill effects aftert donation. Preparing for your donation helps ensure that you will feel fine.
Does it hurt?
Most donors feel only a little pinch and then experience no pain during donation. Our phlebotomists (the staff members who take the blood) are very well trained, talking you through the entire experience.
How often can I donate?
Whole blood donors can donate every 56 days. Red blood cells are the oxygen carrying cells. They can take two weeks or longer to fully return to normal.
You can donate platelets (apheresis donation) every two weeks – up to 24 times in 12 months. Platelet and plasma components are regenerated in the body more quickly than red cells. Platelets will return to normal levels within 24-48 hours of donating. Plasma, the watery substance of your blood, returns to normal levels after a couple of days.
You may donate double red cell units every 112 days.
Can I give blood if I'm afraid of needles?
Most people do feel a bit of nervousness about blood donation; but after their first donation, most say they are sorry they waited so long. Blood donation is a momentary discomfort for the donor that can provide a lifetime of difference for the patient.
Can I give blood if I recently got a tattoo or piercing?
Piercings do not disqualify you from donating blood as long as they were done with single-use, disposable equipment. Tattoos also do not disqualify you from donating if they were done with a single-use needle at a licensed facility. If not professionally done, you must wait one year to donate blood.
Is the blood tested for disease after collection?
All blood product collected are tested for blood type, antibodies and infectious diseases.
Can I exercise after donating blood?
After donation, you should avoid strenuous activities for 24 hours.
How long does it take?
The whole process usually takes about an hour to donate whole blood, and a little over an hour for double red cell donation. When donating platelets, the whole process takes approximately two hours. The blood donation itself usually takes 5-10 minutes for whole blood, 25 minutes for double red cell donation and up to 2 hours for platelet donation.

Am I eligible to donate blood?
To donate blood you must be 16 years old or older and weight at least 120 pounds (16 year olds must have a parent sign our parental consent form). To donate platelets, donors must weigh at least 110 pounds. To donate double red cells, women must be 5'5" or taller and weigh at least 150 lbs; men must be 5'1" or taller and weigh at least 130 lbs.
Are the health history questions necessary every time?
Yes. Screening questions must be asked of all donors each time. This is an FDA requirement.
Will I get paid for giving blood?
CBCC does not pay donors for blood donations. Members of America’s Blood Centers (of which CBCC is a part) draw only volunteer, altruistic donors, who are historically the least likely to have infections that can be transmitted by blood.
How many lives can I save with my donation?
A single blood donation can save three local lives. Donated blood is processed, tested for blood borne diseases, and separated into its components. Each component has a specific use for patients that need blood transfusions. Platelet donors can also save up to three local lives by donating a highly-concentrated number of platelets which can be split among needy patients. Likewise, double red cell donors give a highly-concentrated number of red cells which are split between patients in need.
What are the three components my blood is separated into?
Your whole blood donation is separated into red cells, platelets and plasma. Red cells are used to replace blood volume that may be lost due to an accident, injury or illness. Platelets aid in the clotting process to prevent or stop bleeding and are used in the treatment of illnesses like cancer and for heart patients and transplant patients. Plasma is often used for burn victims or for the treatment of disorders such as immune system deficiencies.
