Q

Why do we want to avoid agglutination in the blood and how does it occur

A

Antigens and matching antibodies can bind together and clump
Can be life-threatening
Blood testing (type and cross) to avoid

Q

What antigens and antibodies are present in blood type A-

A

Antigen: A
Antibodies: anti-b (anti-rh)

17
Q

What antigens and antibodies are present in blood type B+

A

Antigens: B, Rh
Antibodies: anti-a

18
Q

What antigens and antibodies are present in blood type B-

A

Antigen: B
Antibodies: anti-a (anti-rh)

19
Q

What antigens and antibodies are present in blood type AB+

A

Antigens: A, B, Rh
Antibodies: none

20
Q

What antigens and antibodies are present in blood type AB-

A

Antigens: A, B
Antibodies: (anti-rh)

21
Q

What antigens and antibodies are present in blood type O+

A

Antigens: Rh
Antibodies: anti-A and anti-B

22
Q

What antigens and antibodies are present in blood type O-

A

Antigens: none
Antibodies: anti-A, anti-B (anti-Rh)

23
Q

Transfusion scenario: can a recipient with A- blood receive AB+ blood?

A

No! Because A- blood contains anti-B antibodies and potentially anti-rh antibodies

24
Q

Transfusion scenario: could a recipient with O- blood receive B- blood?

A

No! Since O- blood contains anti-B antibodies

25
Q

Transfusion scenario: can a recipient with AB+ blood receive O- blood?

A

Yes! Because AB+ blood has no antibodies, and O- blood has no antigens

26
Q

Which blood type is the universal donor? Why?

A

O-, since they have no antigens

27
Q

Which blood type is the universal recipient? Why?

A

AB+, they have no antibodies

28
Q

Which blood type is this?

A

O+
