define alloantibodies
antibody made from foreign response
define autoantibodies
antibody made from response to self antigen
allergy ad parasitic infections are caused by what Ig
IgE
what secretes CD4
T helper differentiates B cell
what secretes CD8
T suppressor and cytotoxic
what is B lymphs responsible for
humoral immune response
what cells are seen in bacteria and chemotactic
neutrophils
hat cells are seen in parasites and IgE
eosinophils
what cells are seen in histamine, heparin, and anaphylactic reactions
basophils
what is innate immunity
rapid response with physical defenses and cellular defenses like NK cells seen from birth
what is adaptive/acquired immunity
slower response that recognizes the foreign material
what is a humoral response
antibodies against infection creating memory
what is cell mediated response
cytotoxic cells against infection
what is active artificial immunity
vaccine with antigen
what is active natural immunity
disease
what is passive artificial immunity
AB injections
what is passive natural immunity
mothers milk or placental transfer
anti platelet is what disease
purpura
anti IF is what disease
pernicious anemia
what parasite is used in ANA testing
crithidia lucilae
is ANA is negative, what is ruled out
SLE
targets of HIV
CD4 t lymphs
what is used to test HIV
ELISA or HIV-1/2 antigens
polyspecific AHG has what antibodies
IgG, C3d and anti C3b, C4b, C4d
when do you use mono AHG
determine proteins in a positive DAT and in IAT when serum has both complement and non complement
how do you confirm a neg DAT
add Coombs control
what are the uses of DAT
HDN, AIHA, drug hemolytic anemias, transfusion reactions
what causes HDN
maternal IgG cross placenta and bind to fetal RBC
what is AIHA
autoantibodies target own RBC antigens leading to destruction
what does a DAT do for transfusion reactions
a pos DAT means recipients antibodies are reacting to the donors RBCs
what is the IAT used for
in vitro test. It checks for unbound antibodies that are floating in a person's blood plasma in a lab setting.
what is the DAT used for
in vivo test. It checks for antibodies that have already attached to a person's red blood cells inside their body.
can plasma be used to detect complement in IAT
no since plasma has anticoagulants that bind calcium and inactivate complement
what are the temp requirements for anti globulin tests
37C incubation for IAT
RT for DAT
IgM antibodies are associated with what type of antigen panel and blood groups
cold antibodies
ABO, Lewis (Le), MN, P, H, Lua
(Mint Cold)
IgG antibodies are associated with what type of antibody panel and blood groups
warm/37C
Rh, Duffy (Fy), Kell (Kp), Kidd (Jk), S, Lub
(Gas gets Warm)
which antigens react to enzymes
Rh, P, I, Lewis Kidd
(Raw Pineapple, Lemon, Ice, Kiwi)
which antigens are destroyed by enzymes
Duffy, MNS
(Duff Man Destroys)
what does dosage look like
2 of same antigen/homozygous
how are blood types inherited
codominate
which blood group systems have dosage
Rh, MNS, Duffy, Kidd
(Duff Mann Kidd R)
who first discovered the D antibody
levine and stetson 1939
who named D antigen
landseiner and Weiner
what is the most important antigen after A and B
D
donated blood that test neg with anti D but pos for Weak D should be labeled as what
Rh POS
if you are weak D, what blood should you receive
Rh NEG to prevent sensitization
if a patient was pos for an antigen but is no longer, what blood should they receive
Neg (whatever they currently have)
what is the most common class of immunoglobulin
IgG
what is the most important antigens
ABO then Rh
how does maternal antibodies affect HDN
maternal anti-D antibodies coat the newborns D antigens
what sugar does H create
L fucosyltransferase
what sugar does A create
N-acetyl
what sugar does B create
D-galactose
when do antibodies start
after birth due to environment
how can anti-A1 be used for A subgroups
the antisera reacts with A1 but not A2
what is the preferred plant lectin for A1 and A2
Dolichos biflorus agglutinates A1 not A2
what is the primary ABO antibody
IgM does not cross placenta
which ABO cross palcenta
IgG which can cause HDN
what antigen antibody does group A have
A antigen but B antibody
what antigen antibody does group AB have
A and B antigen with no antibody
what antigen antibody does group O have
no antigen but both antibodies
where is anti-B made
group A individuals
where is anti A,B made and why is it dangerous
made in group O as IgG so it can cause HDN
how does leukemia affect ABO
decrease in ABH antigens
what is cell grouping
forward testing patient antigens with known antibodies
what is the ABO based on the cell grouping:
anti-A + but anti-B -
A antigen is present since it reacted to the antisera
group A
what is the ABO based on the cell grouping:
anti-A + but anti-B +
A and B antigen is present since it reacted to the antisera
group AB
what is the ABO based on the cell grouping:
anti-A - but anti-B -
No reaction so
group O
what is serum grouping
reverse testing patient antibodies using known antigens
what is the ABO based on the serum grouping:
A1 + but B -
A antibody is present since it reacted to the antigen
group B
what is the ABO based on the serum grouping:
A1 + but B +
A and B antibody is present since it reacted to the antigen
group O
what is the ABO based on the serum grouping:
A1 - but B -
No antibody so
group ABw
how do you fix a weak antibody
