The area under the curve represents the probability that the
assay result for a randomly chosen positive case will
exceed the result for a randomly chosen negative
case.
The asymptotic significance is less than 0.05, which means that using the assay
is better than guessing.
While the area under the curve is a useful one-statistic
summary of the accuracy of the assay, you
need to be able to choose a specific criterion by
which blood samples are classified and estimate the
sensitivity and
specificity of the assay under that
criterion. See the coordinates of the curve to
compare different cutoffs.
