Since you mention you already have the comparison of each test against 
the golden standard, perhaps the measures obtainable from the confusion 
matrix for especifity, sensitivity, etc. won't help you to ascertain in 
a more complete way?

If you're interested, get a look at epi.tests() in package epiR or 
diagnosis() in package DiagnosisMed.
