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
The Essay on Blood Doping Athlete Increase Process
Each year athlete's abilities to perform and exceed beyond previous year's seems to increase. Better training methods, better conditioning techniques, and better overall health of the athlete can contribute to this increased ability. However, "some athletes always seem to take it a step further. They engage in a process called blood doping." (Beckham, 2002, www). Blood doping, also called induced ...
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
The Essay on Blood Banks Are Getting Safer
THE RED CROSS REPORTS BLOOD BANKS ARE SAFER THAN EVER As spokesperson for the American Red Cross, I would like to address the public s rapidly growing concern over our nation s blood supply. The population of our country must abate their fears regarding contamination of our blood supply from the AIDS virus and hepatitis. Since the early nineteenth century the United States has used intravenous ...
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
The Essay on Aids Epidemic Disease Hiv Spread
HIV/Aids Epidemic HIV/AIDs is a huge epidemic still plaguing society today. The lack of knowledge and technical advances has caused an increasing number of cases. It has made its way around the world since the 1940 s, causing countries to join together in the fight against AIDs. With all the campaigning that has been done the numbers of cases continue to rise. Countries have separated the disease ...
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.
