Using Probability (p) Values

The p value is a statistical tool that increases the confidence that an antibody has been identified with a scientifically acceptable level of uncertainty (0.05).

As applied to antibody identification, it is computed using Fisher's exact test.

  • Tidbit: This is the same Fisher who helped developed the Fisher-Race theory of Rh inheritance.
The p value is calculated using the number of cells that are positive and negative with the patient's plasma.

p values is beyond the scope of this case study. However, a basic overview of p value, its relationship to antibody identification in general, and its application in this Case Study is provided in the attached PDF, if you would like more information.
