Sensitivity Limit in DGA

I don't really know anything about DGA interpretation, but I know that in any form of pass/fail testing you have two criteria: sensitivity and selectivity. Sensitivity determines how many false positives you will get, and selectivity determines how many false negatives you will get.

So a test with very high sensitivity will almost always detect the substance being looked for, but it might also yield a positive result even when the substance is not present. A test with very high selectivity would almost never detect the substance when it is not present, but might also miss the substance when it is present.

The ideal test would never get a false positive or a false negative. In the real world, you want to set your sensitivity to a level where you get an acceptable balance of true positives and false positives.

Like I said, I don't know anything about DGA interpretation, but I hope this points you in the right direction.
