The Safety of Blood
A five-year old girl is riding down the street, on her way to her best friend's house.
She doesn't have a care in the world and is quietly humming to herself. Suddenly a car
whips around the corner and swerves to avoid the child, but he looses control and
squarely hits the girl, causing the her to fall and get trapped between the car and her
battered bicycle. A main artery in her leg has been severed and blood fills the gutter
of the street. As she gets rushed to the hospital in the ambulance, a pint of blood is
given to her to attempt to replace some of the life giving fluid that is pouring out of
her leg. In the end she received four pints of blood and made a full recovery.
Although everything turned out all right for the girl, things could have been much
different. What if that blood hadn't been there because the nation's blood supply was
low? What if the blood that she received had been infected with a deadly disease such as
Syphilis or HIV? These are pressing concerns for today's society. Even though one in
every five people will need a blood transfusion and the risk of contracting a disease
such as AIDS is practically negligible, people are still concerned that the blood that
they receive may have harmful or deadly diseases and that today's blood supply is not
"safe."
However, "safe" means different things for different people. For some, safe is an
absolute security from any danger. This is an extreme viewpoint, though, because most
people realize that one can never be completely safe. Another, and more popularly held
connotation of "safe," is the probability of not getting hurt. This is a much more
reasonable and plausible definition and therefor will be used throughout this paper.
However, even though the overwhelming probability is that nothing will go wrong, people
still fear that the nation's blood supply is unsafe. They are incorrect in this belief,
though, because much is done to assure that the nation's blood supply is, in fact, safe.
One requirement to having a safe blood supply is to have an extensive reserve, because
this allows for the option of discarding any blood that is potentially unsafe. The
assurance of an ample blood supply begins with the donation process. Most of the people
in this country have the capability to donate blood. However, only 4 percent of the
eligible population actually donates.1 There are few restrictions and the reason why
there are blood shortages is because people don't want to donate as opposed to can't
donate. For most blood centers, the physical criteria that a donor must meet are as
follows: person must be at least 17 years of age, weigh 110 pounds, and be in good
physical health. However, if so many people can donate blood why do so few choose to?
Most people are afraid of giving blood. There are many misconceptions about the
process of donating blood and receiving transfusions. For example, people believe that
there is a danger of contracting diseases, especially AIDS, from the needles used during
the process. However, these chances are zero, and a person has less of a chance of
contracting a disease while giving blood than he has in any other ordinary situation
Actually, people have little to fear about giving blood. Many precautions are taken to
assure that the process is safe for the donor, and the blood that is received is safe for
the recipient. Before the donor even gets close to the bed or the needle, he first must
complete a thorough survey asking about his past and potentially risky behavior. The
survey asks about recent sexual encounters, focusing on homosexual situations. It also
asks about drug use, body piercing, and prostitution, which are all considered to be "at
risk behaviors." If the donor has participated in such behavior he will not be allowed
to donate until a time when it is safer for everyone involved. If the donor passes the
screening, his blood is collected in a new, plastic bag with a brand new needle. The
needle and everything used during the process, from the finger lancet to the cotton
swabs, are disposed of instead of being reused, which eliminates the possibility of
something not being properly sterilized. Also, if by chance, the nurse misses the vein
and must reinsert a needle, he will start over with a new needle, to assure sterility.
After the blood is drawn, it is sent to certain laboratories, where it is tested for
diseases such as HIV. If there is a problem, the donor will even be notified to assure
that he or she doesn't put anyone else at risk. At any point in this process, blood that
does not reach the proper standards will be removed from the supply, assuring safety. In
fact, two to ten percent of the units of blood that are received end up being removed
because of uncertainty. 2
Another reason why people may be hesitant to donate is because they don't know the
benefits of giving blood. First, because of the screening process, the donor receives a
sort of mini-physical every eight weeks. This lets a person keep a check on his or her
blood pressure, pulse, temperature, weight, and iron reading. It is a good way to assure
that one is remaining healthy. Also, not only does the blood that is given help someone
in desperate need of it, the donor feels good about himself, too. The donor can walk out
of the center with a firm sense that he has helped someone in need.
After the blood is drawn, many tests are performed on it, providing another way to
insure that the blood supply is safe. Testing is done for Syphilis, Hepititis B and C,
abnormal liver function, and Human T-Lymphotrophic Virus type I and type II. All of
these diseases are blood-born and have the potential of being extremely harmful if not
fatal. However, the main fear that people have regarding a blood transfusion is that
they may contract AIDS. This is a result of a lack of understanding about what AIDS is
or how it is tested.
AIDS, an acronym for acquired immunodeficiency syndrome, is a blood-born disease that
attacks one's immune system, leaving him susceptible to lesser diseases that may not be a
threat to a person with a healthy immune system. It is caused by a virus known as HIV
(human immunodeficiency virus) and over a few years develops into AIDS. The only ways to
contract HIV are through bodily fluids: blood, semen, vaginal fluid, or breast milk. It
is because blood is one of the means of contracting the disease, many people are afraid
of donating and receiving blood. However, HIV is also one of the diseases thoroughly
tested for in the testing process. Two HIV related tests are performed, one for the HIV
antigen and the other for the HIV antibody. The purpose of testing twice is to assure
that the presence of the disease is noticed. If a person tests positive for either the
HIV antigen or antibody, he is permanently deferred, meaning that he will never be
allowed to donate.1
The main reason why people are concerned about the safety of the blood supply is because
they are afraid of contracting a disease in the event that they need to receive blood.
However, precautions are also made to insure the safety of blood transfusions. For
example, all of the blood used for transfusions either comes from the blood center or is
drawn by the same methods. This insures that the level of sterility and testing for
harmful diseases is as high as it is for donation. In the hospital, sterile one-use
needles are also used as they are in the blood center. Also, careful screening is done
to make sure that the blood types match and that the donor blood is compatible with the a
patient's blood, preventing diseases such as jaundice. In both the blood center where
the donations take place and the hospital where the transfusions occur, the staff is
highly trained and knowledgeable. Each nurse or assistant must have basic medical
training to get the job, and although human error exists, it is minimal.
Due to the many safeguards and precautions taken, the blood supply in America is safe.
The risk of contracting a disease from the donation process is quite minimal and there
are more reasons to give blood than not to give blood. It is my opinion that if a person
can give blood, they should. Donating blood is noble, safe, and painless, and when blood
is given, the donor gets a wonderful feeling of doing good for someone and can be
confident that he or she may have saved a life. So when that little girl arrives at the
hospital, unconscious and bleeding, she can be sure that the blood she receives will be
safe.
