Anti-A Serum Anti-B Serum Anti-Rh Serum Blood Type
Slide 1- Mrs. Smith Aggulation No aggulation Aggulation +A
Slide 2- Mr. Jones No aggulation Aggulation No aggulation B
Slide 3- Mr. Green Aggulation Aggulation No aggulation AB
Slide 4- Ms. Brown No aggulation No aggulation No aggulation O
1) Choose one of the following patients:
a) Mr. Smith, Mr. Jones, Mr. Green, Ms. Brown= Mr. Smith
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? A
c) What ABO agglutinin(s) is/are found in the patient’s Plasma? Anti-B
d) What is the patient’s blood type? A
e) If this patient needed a transfusion, what blood type(s) could this patient safely receive? O,A
f) What blood type(s) could safely receive this patient’s blood? A,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 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 Similarities Differences
Found on surface of erthrocytes, blood type is
based on
Produced in blood, part of immune system
found in plasma, production is initiated by amount of A and B antigens that enter the body
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.
WHAT IS BLOOD TYPE? There are four blood types A, B, AB, and O. The type of blood someone has is
determined by the presence or absence of aggulutinogens, or antigens. A person who has A antigens
has anti-B antibodies. A person with B antigens has anti-A antibodies. A person who does not have A
or B antigens has both anti-A and anti-B antibodies. A person who has both A and B antigens has
neither anti-A nor anti-B antibodies. Therefore blood type is based on the antigens, not the
antibodies. Your body can receive transfusions of only certain blood types, depending on the type of
blood they have. If incompatible blood types are mixed agglutinaton occurs. Landsteiner and Wiener
discovered that rabbit sera containing antibodies for the red blood cells of the Rhesus monkey
would agglutinate the red blood cells of 5% of Caucasians. Individuals who possess these antigens
are designated Rh+ and those who do not possess these antigens are designated Rh-.
5) List at least 3 situations where blood typing could be used.
a) Blood transfusions
b) Solving crime
c) Paternity test
6) Define Erythroblastosis Fetalis. Hemolytic disease of the newborn is a blood disorder in a fetus or
newborn infant. Can be life threatening.
a) Describe the sequence of events that lead to this condition. May develop when a mother and
her unborn baby have incompatable blood types. The mother produces antibodies that attack
the baby’s red blood cells.
b) What might be some benefits if the medical profession developed a shot or vaccination that
could desensitize an Rh+ situation? There would be no risk, or harm to the fetus.
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 TYPE A looking for TYPE A/O. I am so red blooded and just looking for that special cell to share
a long lasting transfusion with.
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 is important to take multiple samples to confirm the results and reduce
the risk of human error.
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? Handwashing,
personal protective clothing (gloves, goggles, gowns, masks), satitation of contaminated equipment
used in clinical blood lab (2).
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. If a synthetic blood substitue
was created, those who needed blood in emergency situations would not have to wait for
compatible blood type, or a blood resource to be transported to them.
