4.1
Lewis antigens are made by these cells.
What are tissue cells?
This test method is associated directly with in-vitro procedures
Cold antibodies are of this type and can activate complement.
What is IgM?
Removing antibodies from the serum by adding target antigen, allowing the antibody to bind the antigen is a principle of this?
What is adsorption?
This causes antibodies to be released and RBC antigens to be destroyed.
What is total elution?
No antigens are present on this phenotype
What is little p phenotype
Over specificity is a disadvantage of this type of reagent
What is monospecific AHG reagent?
Antibodies that are directed against the individuals own RBC's.
What are autoantibodies?
This may indicate the need for an intrauterine exchange transfusion.
What is an increasing titer level?
This can be used to investigate HTR's.
What is an antibody screen?
These antibodies react at room temp and are clinically insignificant.
What are M, P1 and I antibodies
Rabbit polyclonal, rabbit/murine blend and murine monoclonal reagents are examples of these types of specific AHG reagents.
What are polyspecific reagents?
Liss, Bovine albumin and PEG are examples of this type of reagent.
What are enhancement reagents?
For this type of adsorption, the patient will be phenotyped.
What is homologous adsorption?
These reagents contains an antibody to C3d.
What are monospecific AHG reagents?
Antibodies to low frequency antigens are often detected through these.
What are unexpected incompatible crossmatches?
Interpreting this requires knowledge of a patient's drug therapy.
What is a positive DAT?
pH and Temp are factors for this.
What are factors influencing sensitivity?
This technique is used when a homozygous expression is on the cell.
What is the exclusion technique?
Rabbit transferrin may be a source of this.
What is contamination?
Aldomet induced hemolytic anemia has been known to cause these to appear.
What is autoantibody-Jka
Too few RBC's being sensitized for detection by routine methods is an example of this factor that can affect an antiglobulin test.
What is the incubation time factor?
Special centrifuges are needed to accommodate these.
What are gel cards?
Antibody coated cells are mixed with this solution.
This autoantibody is seen in leukemia.
What is anti-i?
