Blood Typing Lab Report

b. The blood type (e.g., Type A, B, AB, O) of a group of participants (Mode)

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.

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.

Anna Garcia is a 38-year-old Hispanic female, weighing 165 lbs.; standing 5'4 (64 inches) tall. She was last seen in a grey sweater, walking her dog at 6:30a.m the morning before, by her neighbor, Doug Greene. The same neighbor called police at 9:45a.m claiming that Anna's dog had been barking for approximately two hours and that Anna wasn’t answer the door or calls. She was found DOA lying in her hallway at her house. The body was found at 9: 56 am when police officers broke down her door.

To identify red blood cells, basophils, eosinophils, monocytes, lymphocytes, neutrophils, sickle cell anemia and leukemia.

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

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

Monoclonal Mouse anti-human CD20 reacts with an antigen which is a very useful marker for normal and neoplastic B cells. The B-lymphocyte antigen CD20 causes B-cells to stain brown in the IHC practice, intrafollicular B-cell presence is most notable, however cells stained brown are also present in the interfollicular zone.

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

Another group of antigens that is of much less importance than the HLA antigens is the ABO antigens. This is because, in mixed leukocyte cultures, ABO incompatibility does not cause stimulation. However, they are still important since ABO incompatibility can cause acute rejection of grafts with primary blood supply such as the kidney and the heart. This is mainly due to the high degree of expression ABO blood group antigens in internal organs. Secondly, antibodies to the blood group antigens are present and pre-formed in mismatched recipients. However, there have been advances in medicine that have prevented rejection of the grafts by suppressing the immune system. These have made it possible for organ transplants to be performed across

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.
