Blood Donor FAQ and Fast Facts
|
- One
donation can help save as many as two lives in our region.
- The
Red Cross collects approximately half of the nation's blood supply.
- Approximately
5% of the eligible population in the United States donates blood-4%
of people in the Alabama and Central Gulf Coast region give blood.
It is estimated that 70% are eligible.
How much blood is needed?
- The need for blood is
great – on any given day, we need to collect approximately 800
units of blood to help local hospital patients.
- Blood transfusions are
often needed for trauma victims – due to accidents and burns –
heart surgery, organ transplants and patients receiving treatment
for leukemia, cancer or other diseases such as sickle cell disease.
Keeping
the supply safe
- The
Red Cross has nine National Testing Laboratories (NTLs) that test
samples from all of the blood collected.
Within 18 hours of submitting blood samples to the NTL, test
results are sent back to the blood services region where the
donation was given.
- If testing indicates a
unit of blood may pose a threat to a patient, the unit is destroyed.
The donor is then entered into the Donor Deferral Register, a
national computerized database of more than 250,000 individuals who
are deferred from donating blood.
- Each Red Cross blood donation also undergoes nucleic acid testing
(NAT), an investigational testing method used to detect both HIV-1
and hepatitis C before the body has begun to produce
antibodies.

- Type
O -
is called the universal donor
because it can be given to anybody; it has no proteins to cause
clumps
- Type
AB +
is the universal receiver
because the recipient has all of the proteins and so will not form
clumps
Who
is the average donor in the United States?
- College-educated,
white male, between the ages of 30 and 50, who is married and has an
above-average income
- Persons 65 years and
older compose 13 percent of the population,* but they use 25 percent
of all blood units transfused
- Using current screening
and donation procedures, a growing number of blood banks have found
blood donation by seniors to be safe and practical*

The
importance of minority donations
While
the Red Cross encourages any healthy person meeting the requirements to give
blood to do so as often as possible, minority donors are especially in high
demand. While five percent of the
population donates blood, only 0.5 percent are African-American and Hispanic
donors.
Blood
types and traits are inherited, much like other genetic features such as
eye color. Blood from
African-American or Hispanic donors has different proteins – antigens
– on its surface than blood from Caucasian donors.
As a result, a more complex classification system exists beyond
ABO types to provide a higher degree of similarity between donor and
recipient to ensure that a rejection reaction is less likely to occur.
Blood
Donor FAQ
Who
is eligible to give blood?
In general, to give blood, a donor must be healthy, at least 17 years
old and weigh a minimum of 110 pounds.
Other aspects of each potential donor’s health history are
discussed as part of the donation process before any blood is collected. Each donor receives a brief examination during which
temperature, pulse, blood pressure and blood count (hemoglobin or
hematocrit) are measured.
Is
it safe to give blood?
Yes. The Red Cross ensures
that donating blood is a safe opportunity to give the gift of life. Each
needle used in the procedure is sterile and is disposed of after a
single use. It is important
that all blood donors are in good health, are well-rested and have eaten
prior to donating.
How
often can I donate blood?
People in good health who weigh at least 110 pounds can donate a unit of
blood as often as every eight weeks (56 days).
Please
tell me about the blood donation process.
Donating blood is a four step process, which takes about an hour from
start to finish. The first
step is registration at the reception desk.
The second step is a stop at the health history desk, where
trained professionals will check your blood pressure, iron level and
temperature and will ask specific questions about the potential
donor’s health to ensure that he or she is eligible to donate that
day. The third step is the
actual donation, which takes about 8 - 10 minutes.> The fourth and final step is a visit to the refreshment area
before leaving the blood donation site.
Where
can I go to donate blood?
The Red Cross partners with an extensive network of groups committed to
saving lives, including businesses, high schools, colleges, churches and
other community organizations. People can also donate blood at Red Cross
blood centers. Individuals
wishing to make a blood donation to the Red Cross may call their local
Red Cross Blood Services office or 1-800-GIVE LIFE.
Can
I get a disease if I give/receive blood?
NO, Giving blood: the procedure itself is very safe.
Every donation is taken from a new and sterile needle, which
is immediately disposed of after that single use.
Receiving
blood: it is also a safe process to receive a blood transfusion.
In fact, the risks of contracting a blood-borne disease through
transfusion are far less than the risks of not receiving that
transfusion at all. The
nation's blood supply is safer today than it has ever been and is as
safe as modern science and medicine can make it.
Why
doesn't the Red Cross pay its blood donors to increase the blood supply?
Scientific data shows that people who donate blood for altruistic
reasons are the safest blood donors.
As an extra layer of safety to the blood supply, Red Cross
accepts only volunteer blood donors.
Can
a patient donate his or her own blood for use in surgery?
Yes. When blood
transfusions are anticipated, such as upcoming elective surgery, a
person can donate blood for his or her own use when approved by their
physician. In some cases, it is possible to donate blood for a specific
person.
What
kind of research does the Red Cross conduct?
A scientific staff of more than 250 at the Holland Laboratory focuses
on:
- Improving
the safety and efficacy of blood services in the United States
- Studying
the molecular biology of blood and the immune response
- Developing
new biomedical products and technologies that will address the health needs of
patients worldwide.
Goals
include finding improved ways to produce needed therapeutic plasma products,
developing methods of eliminating residual infectious agents from tested donor
blood and finding new applications for Red Cross products. In addition to the Holland Laboratory, about a dozen Red
Cross Blood Services regions are involved in local research and development
programs, often in collaboration with universities and large teaching
hospitals around the country.
