|
What do the proteins and carbohydrate chains on the surface of RBC's do? What are the proteins and carb chains called?
|
stimulate antibody production by lymphocytes, antigens
|
|
|
What type of antigens will Type A have on the surface of the blood cell?
|
A antigens
|
|
|
Blood type O has what antigens on the surface?
|
neither
|
|
|
What can determine the presence or lack of A or B antigens on the surface of red blood cells?
|
The use of reagent anti A antiserum (Antibodies against the A antigen) and reagent anti-B antisera (antibodies against the B antigen)
|
|
|
What are the reagents in determining the presence or lack of the A or B antigens?
|
They are antibodies against the A or B antigen
|
|
|
What is agglutination?
|
Antibodies, which have 2 arms, can connect 2 RBC's together that have the matching antigen (the thing that stimulates antibody production by lymphocytes)
|
|
|
Antigens that define our blood type are what substance?
|
sugars
|
|
|
What blood type would a person with Anti-A antibodies have?
|
Blood type B, they will have B-antigens
|
|
|
Concerning blood typing, what is in a person's plasma?
|
Naturally occurring antibodies for the A or B antigens that THEY DO NOT HAVE!!
|
|
|
If a person's red cells are agglutinated when mixed with anti-A antibodies, but anti-B antibodies do not agglutinate the red cells, what is their blood type?
|
Type A
|
|
|
If a person sees no agglutination when mixed with anti-A antibodies AND anti-B antibodies, what is their blood type?
|
blood type is O
|
|
|
If a person sees agglutination when mixed with reagent anti-A antisera AND reagent anti-B antisera, what is their blood type?
|
AB
|
|
|
If a person's blood type is known to be O, what reagent antisera would react with their cells?
|
None!
|
|
|
How do the antibodies that are in a person's plasma get there?
|
Not present at birth, they appear over the course of several months after birth as persons are exposed to similar glycoprotein antigens in food and on the surface of bacteria.
|
|
|
What is forward typing?
|
When a person's blood type is identified by reacting his RBC's with reagent typing antibodies (or known reagent antiseras e.g. reagent anti-A antisera/ reagent anti-B antisera)
|
|
|
Who is the universal blood donor? Why?
|
Type O, they don't have A or B antigen on their red cells, so they can donate
|
|
|
Who are the universal blood recipients? Why?
|
Type AB they have AB antigens on their RBC's, but they have NO naturally occurring plasma antibodies against either A or B antigens (NOR do they have antibodies against "O" blood type)
|
|
|
Persons with blood type "AB" antigens on their RBC's have what kind of naturally occurring plasma antibodies?
|
NONE
|
|
|
What kind of naturally occuring antibodies are against O blood type?
|
BOTH anti-A antibody AND anti-B antibody
|
|
|
What will symptoms of a transfusion reaction be?
|
fever, chills, kidney failure, shock, and death
|
|
|
What type of cells can you give people with type O?
|
Type AB
|
|
|
Using what cells, with plasma removed, does what for transfusion?
|
packed cells, simplifies transfusion
|
|
|
Who was the father of modern blood identification---what's the name for blood identification?
|
Father of modern serology was Karl Landsteiner
|
|
|
What is serum?
|
the liquid part of the blood (plasma I'm guessing)
|
|
|
Who is the universal plasma donor?
|
AB
|
|
|
What is the use of blood typing to identify criminals and their victims called?
|
forensic serology
|
|
|
What did Landsteiner mix that helped him identify which blood would agglutinate and which blood would not?
|
the blood and serum from different donors
|
|
|
What is the most common blood type in the U.S.? ...In Europe?
Worldwide, what is the least common ABO type? |
O, type A, least common is type AB
|
