BLOOD FACTS in GENERAL

There is no substitute for human Blood.
Blood makes up about 7% of your body's weight.
An average adult has about 14 to 18 pints of Blood.
One standard unit or pint of Blood equals about two cups.
Blood carries oxygen and nutrients to all of the body.
Blood carries carbon dioxide and other waste products back to the lungs, kidneys and liver for disposal.
Blood fights against infection and helps heal wounds.
One unit of donated whole Blood is separated into components before use (red Blood cells, white Blood cells, plasma, platelets, etc.)
There are four main Blood types: A, B, AB and O.
Each Blood type is either Rh positive or negative.
The three main types of cells making up our Blood are the White Blood cells, Red Blood cells and Platelets:
White Blood Cells (WBCs) are the largest of the three types of cells and are responsible for fighting infections or germs. White Blood cells have a rather short life cycle, living from a few days to a few weeks. One drop of Blood can contain from 7,000 to 25,000 white Blood cells. If an invading infection fights back and persists, that number will significantly increase.
Red Blood Cells (RBCs) make up approximately 40% of Blood volume, carry oxygen to the cells of your body and return to the lungs to excrete carbon dioxide.
Platelets, the smallest of the Blood cells; make up 5% to 7% of total Blood volume. Platelets form a 'mesh' net to form clots in the Blood to help stop bleeding.
There are five types of White Blood Cells (WBCs):
basophil - acts on smooth muscle and Blood cell walls;
eosiniphil - acts against infestations of parasitic larvae;
lymphocyte - recognizes surface markers on cells and targets them for destruction if foreign to the body;
monocyte - formed bone marrow, monocytes migrate into connective tissue and become macrophages; and,
neutrophil - the first line of defense, 100 billion mature neutrophils are released into the body everyday.
There are about one billion red Blood cells in a few drops of whole Blood.
Red Blood cells live about 120 days in our bodies.
Red Blood cells can be stored under normal conditions for up to 42 days.
Frozen red Blood cells can be stored for ten years, and more.
Platelets must be used within five days.
Platelets are small Blood cells that assist in the process of Blood clotting helping those with leukemia and other cancers, controlling bleeding.
Plasma, the fourth major component of Blood, is a sticky, pale yellow fluid mixture of water, protein and salts. It is 95% water. The other 5% is made up of nutrients, proteins and hormones.
Blood Plasma constitutes 55% of the volume of human Blood.
Plasma helps maintain Blood pressure, carries Blood cells, nutrients, enzymes and hormones, and supplies critical proteins for Blood clotting and immunity.
Plasma can be collected from a normal healthy donor twice weekly (max. every 48 hours) and is the most frequently donor paid-for component of Blood. Plasma is often referred to as "the college students beer money."
Type AB plasma has been considered as the universal Blood plasma type, and therefore AB plasma is given to patients with any Blood type.
Frozen Plasma can be stored for up to one year.
Human Blood; red Blood cells, white Blood cells, plasma and platelets are made naturally by the body in the bone marrow.

ABOUT BLOOD CENTERS and DONATION

In the United States, approximately 16 million units of Blood are said to be collected annually. As of November 2000, the American Red Cross (ARC) manages about 45% of the U. S. Blood supply, The American Association of Blood Banks (AABB) manages about 45%, and others such as United Blood Services, manage the remaining 10%.
The mission of Blood trade interest groups and Blood centers is to work with government agencies and other entities to enhance Blood donor screening practices, increase accuracy and types of disease testing, improve Blood tracking systems and ensure good manufacturing practices. These Blood centers and trade interest groups also work with news organizations to improve confidence in the Blood supply.
Approximately 40,000 units of Blood are used each day in the United States; every few seconds someone needs Blood.
Blood centers often run short of type O and B Blood.
Shortages of all types of Blood often occur during the summer and winter holidays.
The actual Blood collection takes approximately 15 minutes. The entire process, from when you sign in to the time you leave, takes about 45 minutes to one hour.
Blood donation takes four steps: medical history, quick physical, donation and snacks.
Anyone who is in good health, is at least 17 years old and weighs at least 110 pounds may donate Blood every 56 days.
Only 5% of healthy Americans donate Blood.
Multiple donations account for over 80% of Blood used for transfusions.
One to two percent of Blood donors are African-American Black.
Giving Blood, under normal rules, will not decrease your strength.
Whole Blood can be donated as often as every 56 days, plasma, no more frequently than every 48 hours, and platelets, a maximum of 24 times a year.
Cancer, transplant and trauma patients and people undergoing open-heart surgery require Platelet transfusions to survive.
Premature infants, children being treated for cancer, and children having heart surgery need Blood and platelets from donors of all types.
Apheresis selective Blood donation that allows a donor to give specific Blood components, such as plasma and platelets.


ABOUT BLOOD TESTING and SAFETY

Most Blood processing facilities perform 11 or 12 basic tests on every unit of donated Blood. Nine of these are for infectious diseases. These tests include screenings for: hepatitis (a liver infection); HIV (the virus that causes AIDS); HTLV-I (a virus associated with a rare form of leukemia); HTLV-II; and syphilis. Other tests are needed, but, are cost prohibitive and therefore not performed. The World Health Organization suggests only nine basic Blood tests.
Approximately 95% of Blood samples taken are tested within 24 hours of arrival at the Blood testing laboratory.
In the United States, for some Blood centers, if testing indicates that a unit of Blood may pose a threat to a patient, that Blood is destroyed. The donor is then entered into the Donor Deferral Register, a national computerized database of more than 250,000 known individuals who are deferred from donating Blood. This system assumes honest donors when selling or donating their Blood, or Blood products. At some point all Blood centers must subscribe to this service.

Every day more is learned about Blood chemistry and the Blood supply. The Blood supply, therefore, is getting safer as more is known about the makeup of Blood and Blood diseases. Looking at the big picture, little is known to date.


SOME EXAMPLES OF AVERAGE BLOOD USE

People older than 65 use 43% of all donated Blood. The demand for Blood and Blood products will increase as the population ages.
25% of all Blood products are used to treat cancer patients.
One out of every ten people entering a hospital requires Blood.
Severe burn victims can need the platelets from about 20 Blood unit donations during their treatment.
The average liver transplant patient needs 40 units of red Blood cells, 30 units of platelets, 20 bags of Cryoprecipitate, and 25 units of fresh frozen plasma.
Using modern techniques, one heart surgery uses, on average, the red Blood cells and platelets provided by from six Blood unit donations.
People who have been in car accidents and suffered massive Blood loss can need transfusions of 50 units or more of red Blood cells.
An organ transplant can use 40 units of Blood; 30 units of platelets; 20 bags of cryoprecipitate; and 25 units of fresh frozen plasma.
The average bone marrow transplant requires the platelets from about 120 donations, and the red Blood cells from about 20 Blood unit donations.


BLOOD AROUND THE WORLD.....

17% of the global population in developed countries benefits from approximately 60% of the 75 million units of Blood donated each year in the world.
The World Health Organization (WHO) requires only nine basic Blood safety tests. Many countries require eleven or twelve or more.
83% of the global population, living in developing countries, has access to only 40% of the Blood supply, and this Blood is collected in 60% of cases from paid or replacement donors rather than from voluntary non-remunerated low-risk Blood donors. Moreover it is not tested for transfusion-transmissible infection in more than 43% of cases. Avoiding the transmission of infection by Blood and Blood product is the other major safety issue, and the bigger issue in developed countries. It is conservatively estimated that approximately 5% of HIV infections world-wide are transmitted through the transfusion of contaminated Blood and Blood products period-red.gif (63 bytes)

 

Pharmacy shelves are stocked with do-it-yourself home tests for Blood glucose, Blood cholesterol paternity tests and pregnancy tests. OraSure Technologies Inc., makes and sells a 20-minute, at-home test that screens for two HIV strains using a swab device that tests saliva, awaiting the FDA.
