The challenges of meeting the blood transfusion requirements in Sub-Saharan Africa: the need for the development of alternatives to allogenic blood
One of the 16 patients from whom 2 units were withdrawn by hemodilution experienced hypovolemia, which was rapidly restored by additional transfusion of colloid. We have a significant challenge to reduce unnecessary demand through world-class management of this precious product and the application of the best available evidenced-based medical practices

The four main categories in the ABO system are: Type AType BType ABType O Your blood type depends on the presence of certain antigens on your red blood cells (RBCs). Results are determined as follows: If your blood cells agglutinate when mixed with anti-A serum, you have blood type A If they agglutinate when mixed with anti-B serum, you have blood type BIf they agglutinate when mixed with both serums, you have blood type AB If they do not agglutinate when either serum is added, you have blood type OBack typing People with type A blood will have anti-B antibodies

Although the majority of HIV infections via blood occur among people who inject drugs (PWID), medical settings still account for a significant number of new HIV infections

Also dissolved in plasma are electrolytes, nutrients and vitamins (absorbed from the intestines or produced by the body), hormones, clotting factors, and proteins such as albumin and immunoglobulins (antibodies to fight infection). As we age this gradually diminishes to just the bones of the spine (vertebrae), breastbone (sternum), ribs, pelvis and small parts of the upper arm and leg

Information on Blood and Blood Types
There are 5 different types of white blood cells produced by the bone marrow, the main two are called, neutrophils, the most numerous of the white blood cells and one of the body's main defences against bacteria and lymphocytes, the second most numerous of the white blood cells, lymphocytes are involved in making antibodies as part of the immune response. One well known, but luckily rare example of this is haemophilia, an inherited condition in which even the smallest injury can cause fatal internal or external bleeding
For example, the surface of red blood cells in Type A blood has antigens known as A-antigens.The Rh Factor Each blood type is also grouped by its Rhesus factor, or Rh factor.

Blood types
What are the possible phenotypes and genotypes of their children? Remember your Punnett square problems? 4 Genotypes AB Ao Bo oo 4 Phenotypes AB A B O 6. Thus, there are four major blood types based only on the ABO group: Plasma carries agglutinins ( antibodies ) to the agglutinogen not carried on the cell membrane
See the table below for information about the antigens and antibodies specific to your blood type: Blood Type A B AB O Antigens A B A and B None Antibodies in Plasma Anti-B Anti-A None Both Anti-A and Anti-B So, what does this table mean? Your blood already contains antibodies against any antigens you do not manufacture yourself. Basically, your anti-B serum antibodies will react with the B antigens in the donor blood and result in agglutinated blood (aggregation of red blood cells into clumps) that destroys the donor's cells
Their red blood cells can be given to a patient with any ABO or Rh blood type, because there are no A, B, or Rh factor antigens on the donor's red blood cells for the antibodies of a patient with a different blood type to react with
Blood Types
Because each of the four main blood groups (A, B, AB, and O) may or may not have Rh factor, scientists further classify blood as either "positive" (meaning it has Rh factor) or "negative" (without Rh factor). But if you have Type O blood, meaning your red blood cells have neither A or B markers, your body will have both A and B antibodies and will therefore feel the need to defend itself against A, B, and AB blood
For example, the surface of red blood cells in Type A blood has antigens known as A-antigens.The Rh Factor Each blood type is also grouped by its Rhesus factor, or Rh factor
Similarly, plasma from type AB group can be transfused to individuals of any blood group while individuals with blood group O can receive plasma from any blood group
Why is a person with O negative blood considered a universal donor, but can only...
O negative is the universal donor because there are absolutely no proteins on the RBCs, which means that anyone can receive that blood without suffering rejection.

any of various classes into which human blood can be divided according to immunological compatibility based on the presence or absence of specific antigens on red blood cells. Today, hospitals always test a blood sample before a transfusion to make sure there is a good match.blood typeAny of various types of blood (notably A, B, AB, O, Rh-positive, Rh-negative) named for the antigen(s) they do or do not contain

During this time, a women who plans to become pregnant, receiving Blood from her husband may pose a small risk to the infants born of these pregnancies. However, for those mothers who are unable to make an autologous donation, the decision to select her husband as a donor should always take this risk under consideration, and specific consultation with your pediatrician on this subject is essential
Animated Blood Types
If the fetal blood cells just happened to be Rh positive and entered the mother's circulatory system, they would be destroyed by the mother's anti-A or anti-B antibodies before her system began to produce anti-Rh immune-type (IgG) antibodies. Because of the time factor involved in building up a concentration (titre) of antibodies, the first transfusion may not cause any major problems; however, a subsequent transfusion of Rh positive blood could be very serious because the recipient will clump all of the incoming blood cells
They are classified as: Type A Type B Type AB Type O Blood is also classified by rhesus (Rh) factor, which refers to a specific red blood cell antigen in the blood
Genes and Blood Type
If the donor blood cells have surface molecules that are different from those of the recipient, antibodies in the recipient's blood recognize the donor blood as foreign. If the donor blood cells have surface molecules that are the same as those of the recipient, the recipient's body will not see them as foreign and will not mount an immune response
What Is the Universal Recipient Blood Type?
O blood has no antigens, and is referred to as universal donor blood, so that will not cause a reaction.Keep in mind that there is a difference between a reaction caused by the transfusion of the wrong type of blood, which can be fatal, and an allergic reaction to the transfusion of blood, which is possible regardless of blood type.Sources:50 Quick Facts. So how is it that the rarest blood type is also the one that is a universal recipient? The answer lies in the antigens that are present in most blood types
