Roger Newson's -senspec- from SSC should do what you want.

I am interested in carrying out a simple two variable ROC analysis.
I want to assess how well low values of my x variable predict a low value of
my y variable (e.g. y variable with cutoff less than 200).
However, if I understand correctly, the conventional ROC analysis in Stata
creates the ROC by using incrementally increasing values of x to predict y.
How do I adapt the analysis so that the AUC result I obtain will
be consistent with the relationship I am interested in quantifying?
