Deck 10: Blood Bank Automation for Transfusion Services

Question 1

LIS interfaces are an important component in automation because of its potential in:

A) recognizing errors in sample ID.
B) flagging discrepancies with previous test results.
C) providing a mechanism for the electronic crossmatch.
D) All of the above

Answer 1

D
The laboratory information system interface (LIS)is an essential component that provides for correct sample recognition and comparison with prior records; in this function,LIS meets some of the criteria for the electronic crossmatch.

Question 2

A smooth layer of cells in the bottom of the well is interpreted as a/an ____________ reaction when the solid-phase red cell adherence method is completed for the antiglobulin test:

A) positive
B) negative
C) indeterminate
D) mixed field

Answer 2

A
A smooth monolayer of cells indicates a positive reaction,while a compact button is a negative reaction.

Question 3

What does a negative reaction in the MTS Gel Test look like in the gel card?

A) pellet of cells at the bottom of the column.
B) layer of cells at the top of the column.
C) cells evenly distributed throughout the column.
D) cells distributed only in the bottom half of the column.

Answer 3

A
The cells at the bottom of the column indicate a negative reaction because no agglutination took place with the antibody suspended in the gel.

Question 4

What is an advantage of the MTS gel technology over test tubes when performing panels?

A) shorter centrifugation time.
B) decreased reagent cost.
C) reduced patient sample requirements.
D) the incubation step is optional.

Question 5

Random access is an important feature in selecting an automated instrument for testing in the transfusion service.What is random access?

A) Ability of multiple users to sign into the system
B) The recognition of various types of barcodes
C) The need for minimal maintenance procedures
D) The ability to accommodate STAT testing

Question 6

The determination of the ABO and D type by the NEO and ECHO uses the same solid-phase red cell adherence technique that is used for the antibody screen.

Question 7

The TANGO,PROVUE,and NEO all use one of the following reagents or components in the indirect antiglobulin test.

A) Washing mechanism
B) Centrifuge
C) Indicator cells
D) Antihuman globulin

Question 8

Which of the following instruments performs assays using gel technology?

A) ECHO
B) PROVUE
C) NEO
D) TANGO

Question 9

Which of the following items is required before implementing new automation technology into the transfusion service setting?

A) Validation
B) Training
C) Written procedures
D) All of the above

Question 10

The PROVUE,TANGO,and NEO have the ability to perform all of the following tests except:

A) ABO/D typing.
B) antibody ID panels.
C) direct antiglobulin test.
D) acid elution.
