1)      Choose one of the following patients:
a)      Mr. Smith, Mr. Jones, Mr. Green, Ms. Brown=  Mr. Brown
b)      Using the information shown in Figure 1 on Blood type and the data recorded in Table 1, What agglutinogens are present on the patient’s RBC’s? clear
c)       What ABO agglutinin(s) is/are found in the patient’s Plasma? none
d)      What is the patient’s blood type? O positive
e)      If this patient needed a transfusion, what blood type(s) could this patient safely receive? All types
f)       What blood type(s) could safely receive this patient’s blood? none
2)      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
B: No Agglutination
Rh: Agglutination
Medical technologist’s report
·         ABO Type: A
·         Rh Type: positive








3)      Compare and Contrast agglutinogens and agglutinins.  In the diagram show at least 2 similarities and 2 differences.
Agglutinogens                                                                              
Agglutinins
Differences
Clear and not cloudy
Similarities
Both determine if blood is positive or negative.
Differences
Cloudy not clear


4)      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.
Blood type is determined by if blood aggulates or doesn’t. A doctor would draw a patients blood. After drawing the patients blood the doctor would go to the lab and put 3 drops of blood in 3 separte holes. The doctor would then put anti-a serum in one hole, anit-b in another and anti-Rh in the last. He would stir up the blood and serum together and see what happens to the blood. If the blood is clumby and clear and isn’t very liquidy it has aggulated. If one of the anti serums matches with the Rh then that determines the blood type. For example if the hole where the doctor inserted the anti-a serum and the hole with the anti-Rh  are both cloudy and non agglution then the blood type is A. to determin if its positive or negative you look at the Rh hole. If its agglunation/ clumpy its positive. If its not and its cloudy and liquidy its negative.

5)      List at least 3 situations where blood typing could be used.
a)      Donating blood
b)      A open heart surgery
c)       Blood doping
6)      Define Erythroblastosis Fetalis. severe anemia in newborn babies; the result of Rh incompatibility between maternal and fetal blood.
a)      Describe the sequence of events that lead to this condition. typically occurs when the child of an Rh-negative mother inherits Rh-positive blood from the father; can be diagnosed before birth by amniocentesis
b)      What might be some benefits if the medical profession developed a shot or vaccination that could desensitize an Rh+ situation? No more erythroblastosis fetalis
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 have type A erythorocyte which means I am severly amenic. Ive had it since I was a baby and I reject my mothers blood. I need someone who is opposite of my mother to supply blood for me whenever I need it.
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. Being able to figure out how many red blood cells a person has because if a person is making too many red blood cells or too little both can be very dangerous and its good to have a tool that can see how many cells a person has to be able to figure out why one person has this disease or something similar to that. 
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? When someone gets a cut they can be sure that blood doesn’t get on any one or anything and if it does it should be immediately sterilized. Also monthy a person should go into a lab and get their blood set aside for if an emergency was to occur, having to get rid of a lot of their blood cuz it is diseased, they would have amble amount if needed.
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. Being able to make real blood. Every year americans donate tons and tons of blood to save those who need blood from either loosing a bunch of it or need extra blood when undergoing a surgery. If scientist could make real blood that a patient could use it would be the same as a person donating their and this could save money for hospitals on supplies for blood donations and such.
