Blood Donor FAQs

Whether you’re 16 or 96, you can help Central Jersey Blood Center in its mission to provide an adequate, high-quality, and safe supply of blood and blood products to hospitals in New Jersey. Here are answers to some of the most frequently asked questions that we receive about blood donation, the benefits of blood donation, and the donation process.

1. Am I Eligible to Donate Blood?

At a glance, blood donors must be at least 16 years of age, must weigh at least 120 pounds, and must have never had hepatitis. In New Jersey, those who are 16 must have parental consent, while anybody over 17 can donate blood without a parent’s or guardian’s consent. Medications frequently taken by healthy individuals, such as aspirin, diet pills, birth control pills, blood pressure medication, and cholesterol medication are not a reason for deferral. The use of other medications will be evaluated by a nurse. To learn more about specific blood donor eligibilityclick here.

2. What is blood? What are blood components?

Blood is living tissue that circulates throughout the body. It is made up of plasma, red cells, white cells, and platelets. Plasma brings water and nutrients to every cell in the body; it also sends waste products to the kidneys for excretion. Red cells are carriers of oxygen from the lungs to the entire body. White cells are protectors against disease and infection. They destroy bacteria and help immune defense. Platelets control bleeding; they are tiny cells that help blood to clot.

3. What is plateletpheresis?

Plateletpheresis is the process of collecting a single component of blood—platelets. These tiny cells help blood to clot. As an individual undergoes chemotherapy, they require platelets as a part of their treatment. Diseases such as leukemia that were once 100% fatal are now being treated and often cured by a combination of modern medicine and repeated transfusions of platelets.

4. Why should I donate blood?

There are several reasons to donate blood in NJ, mainly because blood is perishable and supplies of it need to be regularly replenished.

 14. Can I bring my child with me when I come to donate blood?

It depends.  If you are coming to donate at one of our donor centers in Shrewsbury, Howell, or Toms River, your child may accompany you, but will be asked to wait in either our waiting room lobby or in the refreshment area to ensure everyone’s safety.  Please note, your child must be of mature enough age to be left unsupervised.

If you are coming to donate at a blood drive held on a bloodmobile, due to the limited amount of space, we do not allow for visitors to accompany the blood donors on the mobile vehicle.  Blood drives that are held in indoor locations may be able to accommodate children or other visitors, but please note that each location is unique.  We ask that you please check with your group’s blood drive Coordinator or Account Rep prior to presenting to donate.
