Term
What are the phases and associated temperatures used in antibody id |
|
Definition
immediate spin- no temp detected
37.C albumin/ LISS- 37.C
AHG- 37.C |
|
|
Term
what is the priniciple of the antibody id procedure |
|
Definition
establish a pattern of reactivity; pattern established by the series of positive/negative reactions that are seen when testing the serum with the panel cells. antibody id is most often concerned w/ non- ABO antibodies that may appear in a patients serum |
|
|
Term
how do you read reactions for antibody id |
|
Definition
reactions are read macroscopically for aggulation and/or hemolysis.
all positive reactions must be graded for their strength |
|
|
Term
serological properties (antibody id) |
|
Definition
phase /temp reactions; strength of reaction; presence or absence of hemolysis reactions; lewis system antibodies can react at all phases and temps |
|
|
Term
specific specimen requirement and collection procedures |
|
Definition
fresh within 72 hrs of drawing if refrigerated; non-hemolyzed; red- top collection tube ( serum separators may bind antibodies) |
|
|
Term
factors that cause inaccurate antibody id results |
|
Definition
rouleaux seen in saline/albumin phases not in AHG phase.
solve by using saline replacement technique |
|
|
Term
quality control requirements for antibody id |
|
Definition
consists of a mixture of the persons own red cells/serum ran through same temps and phases as other tubes.
most often negative |
|
|
Term
|
Definition
after ruling out process only one antigen remains- antibody identified |
|
|
Term
|
Definition
after ruling out process multiple antibodies remain; additional testing done on remaining antibodies using additional cells; additional cells must lack one of the antigens but possess the other
3 plus rule |
