Question
A medical technology intern was assigned to the serology section of a clinical laboratory.
His supervisor asked him to prepare a 5% red cell suspension, which will be used to run a
hemagglutination inhibition assay. The intern, being aware of the importance of preparing
the desired concentration of red cells recommended in the assay, considers the factors
enumerated on the table below during the sample processing.
If you are the intern assigned to the task, explain why these factors are vital to the
procedure and determine their effect on the sensitivity of the test.
