Different Blood Types

There may be many different substances in the person's blood. Different blood cells tell you different things. Red

13. Know the ABO and Rh typing system: what antigens are expressed, how one tests for the antigens, and the significance in transfusions, etc.

There are four blood types found in humans. These are A blood type which has the genotype either AA or AO, B blood type which has the genotype either BB or BO, AB blood type which has the genotype AB, and O blood type which has the genotype OO. These genotypes show a combination of complete dominance and codominance. A and B traits are dominant to the recessive O trait, however, the A trait is codominant to the B trait. Each blood type codes for certain antigens. A blood codes for the A surface antigen, B blood codes for the B surface antigen, AB blood codes for both the A and B surface antigen, and O blood does not code for a surface antigen. Therefore to determine one’s blood type a test can be performed

The general charactertics of blood are color, composition, and pH. The composition of blood is determined by collecting blood from a person then it’s placed in a centrifuge which shows plasma is 55% of whole blood and 45 % is erythrocytes. Another name for red blood cells is erythrocytes which are small sacs of blood that carry oxygen and

t all began in 1818 according to the Blood Centers of the Pacific the first recorded successful human blood transfusion was accomplished during this era. However due to the lack of knowledge and research, it was followed by many blood transfusion failures. But 80 years later, scientists discovered that our red blood cells are different from one another, which was the cause of many incompatibilities blood transfusions in the 1800's. Due to this four blood types were identified - A, B, AB and O. This discovery revolutionized hematology and led the way for successful blood transfusions.

Hypothesis – With the antigen and antibody reaction we can determine ABO and Rh blood types by using certain antiserums. If an A Antigen ever comes in contact with an Anti a antibody then the blood will have a reaction. Also if a B Antigen comes in contact with a B anti body then the blood will

To explain the ABO and Rh blood groups and to identify the universal donor and the universal acceptor (recipient).

A 13 year old is studying blood in school, and has asked some questions that haven't been answered in class. I will answer

Blood typing is a way to identify and match blood samples. Three separate tests are performed. The patient 's blood is mixed with antibodies that bind to the A protein. If the patient 's blood clumps or agglutinates, that means that the person 's blood contains protein A. If the blood being tested does not react with the antibodies that bind the A protein, then that person 's blood does not contain protein A. Similar testing

Why is cross-matching performed, even though both donor and recipient are known to be the same blood type? A. it reveals the presence of potential cross reactions with surface antigens other than A, B, and RH.

Human have different types of blood cells within the body, this includes plasma, platelets, red blood cells and white blood cells.

The system works because in blood there are antigens and agglutinogens. In type A, only type A antigens on the red blood cells. Similar to this type B only has type B antigens. Type AB has both A and B antigens, which is why it is the universal recipient. Type O has neither A or B antigens making it the universal donor.

In 1667, Jean-Baptiste Denis from France reported transfusing blood from lambs into human, which was later declared illegal. An American physician, from Philadelphia, performed the first human to human blood transfusion but did not report it when he did so in 1795. James Blundell, a british obstetrician, successfully performed a transfusion for a patient with postpartum hemorrhage in 1818 and later performed 10 more and half were successful. In 1840, Samuel Armstrong Lane helped with the first transfusion to treat hemophilia and in 1867, and English surgeon named Joseph Lister used antiseptics to reduce the risk of infections during transfusions. In 1900 an Austrian physician discovered the first 3 human blood groups, A, B, and C that was later renamed O. Hepatitis B was found in blood n 1971 so testing on donor blood began and in 1985, the first blood screening test for HIV was licensed and used in blood banks around the world to protect the supply of blood.

Since, the patient’s blood type is B+, he can safe and sound receive blood types B+, B-, O+, and O-. The blood types B+, B-, O+, and O- are well-matched with this patient Type B+, and supported with the point that he merely has the B antigen on red blood cells and an A antibody in the plasma. In the case of where the person has blood group O means that the person has neither A nor B antigens on red cells

Blood grouping involves the use of ABO system as described by Karl Landsteiner. The grouping came into existence in the year 1900 after discovery by Nobel Prize winner Karl Landsteiner. He first discovered three blood types A, B, and O, but after two years he discovered the fourth blood group AB. This discovery led to four major types of blood that includes A, AB, B and O. The grouping depends on the presence of two chief antigens and antibodies. The two antigens responsible for blood grouping include A and B while the antibodies include anti-A and anti-B. The combination of the two antigens and antibodies thus determines the blood types. The blood type A has antigen A and antibody anti-B. The blood group B express Antigen B and antibody anti-A (Reid and Lomas, 2004). Blood group O express no antigen but possess antibodies
