Exam 12: Blood Bank Technologies and Automation

Low ionic strength saline (LISS) is added to antibody screening methods for which of the following test systems?

SPRCA testing requires the use of all of these specialized microplate equipment EXCEPT:

Which of the following tests is not available for both the gel testing method and solid phase technology?

Manufacturers Grifols and Ortho both produce automated blood bank equipment that uses

In a gel-based technology, the solid band at the top of the gel indicates a , whereas formation of a pellet at the bottom of the microtubes indicates .

Using the gel test system, the technologist used a 3% cell solution. What would be the probable outcome?

Special pipettes are required for this method.

Upon centrifugation of an antibody screen procedure done by the gel system, the red blood cell agglutinates are dispersed throughout the gel column with a few agglutinates at the bottom of the microtubes. This reaction should be graded as a:

The FDA has approved the for application of gel technology.

Using the affinity column technique, a serologic reaction that forms a fine red blood cell band at the top of the gel column and a red blood cell button at the bottom of the gel column is interpreted as:

A layer of red blood cells agglutinates at the top of the gel media, and a pellet of unagglutinated red blood cells forms at the bottom. These findings are comparable to which of the following reactions in the test tube?

Which of the following statements is the most accurate? A mixed-field in the gel system:

Which of the following substances may interfere with gel technology but not SPRCA technology?

When performing an antibody screen by gel technology, the following steps are eliminated:

The indicator cells used to detect antibodies in a solid phase technology are:

If you had a lipemic and icteric sample that needed to have an antibody screen done, which of the following would obtain the best results?

An anti-M detected by using gel AHG antibody screening cards is considered clinically insignificant.

The gel system has all of the following advantages over the traditional tube procedure except:

In performing an antibody screen by the solid phase technique, a monolayer of red blood cells is formed at the top of the microplate wells following the addition of indicator cells. This result should be interpreted as:

Which of the following factors are likely to cause false-positive results while using gel technology?
