Exam 7: Antibody Detection and Identification

Match the tentative interpretation of antibody screen and direct antiglobulin test (DAT)with the results given below. -All screening cells 2+ at antihuman globulin phase,DAT positive,IgG 2+

Anti-Sd^a should be suspected if:

Match the tentative interpretation of antibody screen and direct antiglobulin test (DAT)with the results given below. -One screening cell 1+ at antihuman globulin phase,DAT negative

The next step in investigating a positive direct antiglobulin test using polyspecific antihuman globulin reagent should be to:

The best description of the elution technique is that it is a technique used to:

Antibodies to low-incidence antigens include all of the following except:

All the following antigens are commonly found on screening cells except:

In an antibody identification panel,only one red cell was negative at the antihuman globulin phase.On ruling out and matching the pattern,an anti-k was identified.What further testing is necessary to confirm the antibody?

Which of the following medications is most likely to cause the production of autoantibodies?

Match the tentative interpretation of antibody screen and direct antiglobulin test (DAT)with the results given below. -All screening cells positive 1+ at IS,DAT positive,C3 1+

In the process of identifying an antibody,the technologist observed 2+ reactions with 3 of the 10 cells in a panel at the immediate spin phase.These reactions disappeared following incubation at 37 ^$\circ$ C and the antihuman globulin phase of testing.The antibody most likely to be responsible is:

Match the tentative interpretation of antibody screen and direct antiglobulin test (DAT)with the results given below. -All screening cells positive 1+ at IS,DAT negative

An example of a cold alloantibody includes:

A patient's serum reacted weakly with all panel cells tested at the antiglobulin phase using LISS and were not enhanced using PEG.The autocontrol was negative.Ficin-treated panel cells were nonreactive.What is the most likely specificity of the antibody?

If an anti-I is suspected in a patient's sample that requires a transfusion,the most acceptable course of action is to:

High-titer,low-avidity antibodies typically:

DTT (dithiothreitol)would be useful in the identification of which of the following antibodies?

Proteolytic enzymes should not be used to screen for antibodies because:

An autoadsorption uses what type of cells to remove antibody from the serum?

The phase of the agglutination reaction is important in the interpretation of the antibody screen or antibody identification panel because it:
