Anti-Le^a, Anti-Le^b
Choose an answer
Antibodies may be removed from
serum by adding the target antigen Occur in the serum of Le(a-b-)
1 2
and allowing the antibody to bind to secretors
the antigen
During elution, the last wash should Used to remove antibodies by using
3 4
be what? patient's own RBCs
Don't know?
Terms in this set (166)
,Antibodies may be removed from Adsorption
serum by adding the target antigen
and allowing the antibody to bind to
the antigen
Possesses I, H, and H-like structures Rabbit Erythrcyte Stroma (RESt)
Incubating the patient's serum at 4 RESt
degrees Celsius with this reagent will
remove insignificant antibodies,
which may interfere with detection of
clinically significant warm-reacting
antibodies
Adsorption testing methods Auto
Homologous
Differential
Used to remove antibodies by using Auto adsorption
patient's own RBCs
Which adsorption method(s) can be Homologous, differential
used when a patient is so anemic,
that there is not enough autologous
RBCs available to perform an
adequate number of adsorptions or
when a patient has been recently
transfused (due to donor RBCs in the
specimen possibly adsorbing
alloantibodies)
, The patient is phenotypes, and then Homologous adsorption
phenotypically matched RBCs are
used for the adsorption in place of
autologous cells
Which adsorption method(s) can be Differential adsorption
used when phenotyping the patient
is difficult because of a positive DAT
or recent transfusion?
Used to release, concentrate, and Elution
purify the antibodies
Elution removes the antibody by: Changing the thermodynamics of the environment
Changing the attractive forces between antigen
and antibody
Changing the structure of the RBC surface
Most critical step in Elution Initial washing, which removes unbound antibodies
and may contaminate the eluate
The supernatant of the last wash, In parallel
during elution, should be tested in
what way with the eluate as a
control?
During elution, the last wash should The last wash should be nonreactive when tested?
be what?
