Opportunity, from everything written from Abbott, they did all their testing with RECAF involving prostate cancer. It is obvious they were wanting to combine RECAF and PSA and it is also obvious they felt it would not work to their satisfaction. That is why they are gone.
If it is not satisfactory with PSA, why do you think it would now be acceptable with others?
I'll give you a little hint Opportunity, RECAF has problems differentiating normals from abnormals and it's the reason for the large number of false positives. Two bad tests do not make a good test.
