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:
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:
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:
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?
After completing an antibody screen using the gel testing method, results after centrifugation yield a pellet of unagglutinated cells at the bottom of the microtube and a thin layer of cells at the top gel column. This situation commonly indicates:
