1. Mr. Green's blood sample showed agglutination with anti-A, anti-B, and anti-Rh sera, indicating his blood type is AB Rh+. He could safely receive blood from types O, A, B, and AB. 2. Agglutinogens are antigens on red blood cells while agglutinins are antibodies found in plasma. Some similarities are that they are both related to blood typing - agglutinogens determine blood type while agglutinins identify non-self blood. A difference is that agglutinogens are on red blood cells while agglutinins are antibodies in plasma. 3. Blood typing is determined in hospitals by mixing patient blood samples with anti

Slide 1- Mrs. Smith Agglutination None Agglutination A+

1) Choose one of the following patients:
a) Mr. Smith, Mr. Jones, Mr. Green, Ms. Brown= Mr. Green
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? Antigens A and B
c) What ABO agglutinin(s) is/are found in the patient’s Plasma? Neither anti-A or anti-B
d) What is the patient’s blood type? AB
e) If this patient needed a transfusion, what blood type(s) could this patient safely receive? Blood
types O, A, B, and AB.
f) What blood type(s) could safely receive this patient’s blood? Only blood type AB
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 Medical technologist’s report
B: No Agglutination  ABO Type: AB
Rh: Agglutination  Rh Type: Rh+
3) Compare and Contrast agglutinogens and agglutinins. In the diagram show at least 2 similarities and
2 differences.
Agglutinogens Agglutinins

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.
As we enter the cold sterilized room I notice the line of what looks like small refridgerators that hous
the packages of blood for transfusions. The main doctor escorting me through this wing of the
hospital informs me that the holders are sectioned of by blood type for accessability purposes.
There is a large machine near the back of the room that is supposed to determine the type of blood
that the nurses bring in. The machine is filled with anti-A, anti-B and Rh serums that it dispenses into
test tubes filled with patient or donor blood. After stirring the contents of the test tubes the
machine distinguishes which tube contains agglutinations and determines the type of blood and
where it should be stored.
5) List at least 3 situations where blood typing could be used.
a) Transplants
b) Transfusions
c) Blood donations
6) Define Erythroblastosis Fetalis. Infant/Fetus blood disorders
a) Describe the sequence of events that lead to this condition. Opposite Rh conditions (+/-)
b) What might be some benefits if the medical profession developed a shot or vaccination that
could desensitize an Rh+ situation? Less deaths at birth
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.
Do you need a transplant/transfusion/blood donor lifetime partner??? I know I sure do and I tos of
fun to be around. If we are not compatible at all then I am afraid things will not progress further in
our relationship. I do hope you understand, neither of us would benefit from a
disasterouscombination of antigens and anit-bodies. I am only looking for someone to help keep me
living and who I can return this favor to.
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. It allows doctors to have a cell count.
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? Take extra

3. precautions: 2 pairs of gloves, more labels to avoid confusion, designated people for specific blood
samples to keep things more organized and prevent someone picking up a blood sample that is not
the one they 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. Making cures or finding new
technology that can find the perfect cure for certain diseases but specific for the person depending
on their blood type. For instance, blood clotting medicines based on blood type, and possible and
deeper understanding of AIDs.
