Blood Typing And The Blood Of The Donor Blood

Type AB: The genotype is AB. The antigens on the blood cell are A and B. There are no A or B antibodies in the blood plasma.

3. At this point, you are ready to begin the lab exercise. Click on the “Information” button on the blood

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

The group started by testing the controls. The group then added two drops of a blood sample to spot A and spot B on a blood typing slide. After the blood samples were added to the spots, the group added the appropriate antiserum to each of the samples. The group stirred each blood type and antiserum for 10 seconds with a clean toothpick.

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 goal of this experiment is to determine the blood types of the samples given and to learn what interactions occurred to each blood type. Determining an individual’s blood type and how it reacts with Anti A, Anti-B, and Anti Rh serums played a crucial part in this experiment. The researcher concluded that agglutination (clumping) occurred in some of the blood samples. For example, Mr. Smith’s blood reacted with Anti-A and Anti-Rh serums (antibodies) allowing the researcher to determine the blood type is A. Mr. Jones’s blood reacted with Anti-B serum but it did not react to Anti-A or Anti Rh allowing the researcher to believe that the blood type is B. Mr. Green’s blood reacted with all serums and caused a reaction to occur resulting the blood type to be AB positive. Mr. Green’s blood also had a positive marker for Rh factor. However, Ms. Brown’s blood had no reaction at all and the researcher determined if no reaction occurred then the sample had no antigens but proved to have some antibodies, resulting in blood type to be O. The purpose of this experiment is to determine whose blood has type A, B, AB, or O.

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.

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

The homogenate used in this experiment was liver homogenate. Five different samples and a blank

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

Thank you for taking the time to review my senior project: hosting an American Red Cross blood drive. I nearly chose to job shadow instead, but after taking some time to think about my main weaknesses, I decided that a blood drive would help me improve in these areas more than job shadowing. The main shortcoming I sought to improve was a general shyness around strangers; organizing a blood drive takes more planning and interaction with strangers than most job shadowing.

The Rh status of the blood is determined by a simple blood test which is administered on the mother in the early stages of pregnancy and sometimes on the father as well if he is believed to be Rh positive; it states the +positive or –negative symbol after the blood type, indicating if the red blood cells have a

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

Blood chemistry or blood test is identifying the different levels of chemical ingredients found in the blood. The analysis of these substances provides clues to a patient’s condition and the functioning of the major body systems such as, blood sugar levels, liver functions, essential nutrients etc. This helps doctors in diagnosing the patient’s conditions much easier and quicker.
