Blood donation

Resolve to Give

National Blood Donor Month

"Resolve to Give", that is the thought of this year's annual Blood Donor Month. January is the month that the American Red Cross celebrates the donors of blood and platelets.

So roll up your sleeve and consider giving.

January 1970 is when National Blood donor Month was first observed. The goal is to increase donations of blood and platelets during the winter months.

How to schedule a donation appointment?

You can download the American Red Cross Blood Donor App by visiting redcrossblood.org.

Or you can call 1-800-RED-Cross (1-800-733-2767).

What do I need to bring to the appointment?

Your blood donor card -if you have one. Or a driver's license or two other forms of identification.

You must 17 years old (or 16 with parental consent in some states), weigh at least 110 pounds and be in good health. Those under 18 years old may have additional height and weight requirements.

Blood Types

Below is information that I took directly from the Red Cross website. It is very good. The site is http://www.redcrossblood.org/learn-about-blood/blood-types

Although all blood is made of the same basic elements, not all blood is alike. In fact, there are eight different common blood types, which are determined by the presence or absence of certain antigens – substances that can trigger an immune response if they are foreign to the body. Since some antigens can trigger a patient's immune system to attack the transfused blood, safe blood transfusions depend on careful blood typing and cross-matching.

The ABO Blood Group System

There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells:

1. Group A – has only the A antigen on red cells (and B antibody in the plasma)

2. Group B – has only the B antigen on red cells (and A antibody in the plasma)

3. Group AB – has both A and B antigens on red cells (but neither A nor B antibody in the plasma)

4. Group O – has neither A nor B antigens on red cells (but both A and B antibody are in the plasma)

There are very specific ways in which blood types must be matched for a safe transfusion.

1. In addition to the A and B antigens, there is a third antigen called the Rh factor, which can be either present (+) or absent ( – ). In general, Rh negative blood is given to Rh-negative patients, and Rh positive blood or Rh negative blood may be given to Rh positive patients.

2. The universal red cell donor has Type O negative blood type.

3. The universal plasma donor has Type AB blood type.

Blood Types and the Population

O positive is the most common blood type. Not all ethnic groups have the same mix of these blood types. Hispanic people, for example, have a relatively high number of O’s, while Asian people have a relatively high number of B’s. The mix of the different blood types in the U.S. population is:

Some patients require a closer blood match than that provided by the ABO positive/negative blood typing. For example, sometimes if the donor and recipient are from the same ethnic background the chance of a reaction can be reduced. That’s why an African-American blood donation may be the best hope for the needs of patients with sickle cell disease, 98 percent of whom are of African-American descent.
