Truth Table
The Truth Table, showing sensitivity and specificity and the analysis of the false
negative results, is presented in this section. For the distributional analysis,
absolute limits were used. The data is based on the evaluation of a total of 848
cases.
In Table 4.17:
TP
= True Positive
TN
= True Negative
FP
= False Positive
FN
= False Negative
Agreement
= 98.0%
False Positives
= 3.19%
False Negatives = 0.53%
Specificity
= 96.81%
Sensitivity
= 99.47%
Table 4.18 shows the manual differential and CELL-DYN 3200 differential for
false negative results.
