B c) What ABO agglutinin(s) is/are found in the patient’s Plasma? Anti-A d) What is the patient’s blood type? B e) If this patient needed a transfusion, what blood type(s) could this patient safely receive? O,B f) What blood type(s) could safely receive this patient’s blood? B, AB2) Below is the information representing the blood type analysis of a new patient (patient X). From the information obtained, fill out the medical technologist report. A: Agglutination Medical technologist’s report B: No Agglutination ABO Type: AB Rh: Agglutination Rh Type: positive3) Compare and Contrast agglutinogens and agglutinins. In the diagram show at least 2 similarities and 2 differences. Agglutinogens Agglutinins Differences Similarities Differences
Found in erythrocytes, blood Both produced in blood, both Found in plasma, does not typing is based on part of the immune system contribute to blood typing agglutinogens4) Pretend you went with your class on a medical career field trip to a local hospital. One of the stops on the visit was to the hospital’s blood lab. The medical technologist at this stop gave a demonstration of how blood types are determined. Your job is to write a paragraph for the school newspaper on the visit to the blood lab, summarizing what you’ve learned about how ABO/Rh blood groups are determined. Write a paragraph and include the title. How ABO/Rh blood groups are determined- the blood typing lab determines blood types by mixing different antogens with the blood. To determine the type the different antoge ns are added when they are mixed some will aggulate. If the different antogens cause aggulation then they result in determining the blood type, if aggulation is seen with anti- A serum and not with anti-B serum then the blood type is A. if there is no aggulation with the anti-A serum but there is with the Anti-B serum the blood type is B. if there is no aggulation with either serum, the blood type is O. if there is aggulation in both serums tthen the blood type is AB. If the anti -Rh serum aggulates the blood type is positive, if it does not the blood type is negative.5) List at least 3 situations where blood typing could be used. a) Paternity tests b) DNA analysis c) Blood transfusions6) Define Erythroblastosis Fetalis. Blood disorder in a fetus or new born infant a) Describe the sequence of events that lead to this condition. This happens when a woman with Rh- positive blood conceives a baby with Rh- positive blood. Their blood types are incompatible, causing anemia in the baby. b) What might be some benefits if the medical profession developed a shot or vaccination that could desensitize an Rh+ situation? This would cause the babys red blood cells that may have been crossed into the mothers blood to be destroyed before sensitizing the mothers immune system.7) You are a type A eryhthorocyte placing an ad in the personals and you are seeking a compatible mate for a long lasting transfusion. Create an ad to be submitted to the newspaper. I am a very lonely erythrocyte looking for a long lasting relationship, my compatible mate must like diffusion of oxygen and carbon dioxide, along with romantic walks on the beach. I am type A and find myself very easy going when it comes to going through the capilarries that life throws at me. If you don’t have a cell nucleous you can still be chosen as my mate!8) Another important diagnostic tool used by medical technologist is determining a patient’s blood cell count, for both red blood cells and white blood cells. When this procedure is performed, one technique used is to take multiple samples and calculate the average. This method of multiple sampling is a standard procedure in scientific and medical investigations. Discuss why this method is
important in blood typing. This method is important in both scientific and medical investications to make sure that the data that has been collected is completely accurate. This makes it even more important when blood typing because if the cell count is off and a false diagnosis is calculated it could result in death.9) Each year thousands of people contract blood borne diseases. What could be done in a clinical blood lab to minimize the risk of obtaining or spreading a blood borne disease? To minimize the risk of obtaining or spreading blood diseases the clinical blood labs should wash hands after patient contact, use gloves, masks, gowns, and goggles to protect themselves, and disinfect and sterilize the equipment after they have used it.10) In a short paragraph, identify what you think may be the next important breakthrough, milestone or discovery in the study of blood and blood diseases and explain why. I think that the next major breakthrough would be that the doctors find out something that would cause the donor blood not to clot when its mixed with the wrong person. This way anyone can get any blood if they need it without dying.
