>>>those were the days back then and it sure would have been supper with Abbot and Quest...it seemed we were so close>>>

Oh yeah, I followed the Quest Dx/Abbott partnership closely back in those days. Dr. Barnhill had success, via his clinical laboratory, creating assays (LDTs or lab-developed-testing) in the 1990s. He developed a more sensitive and specific PSA test which I personally marketing while at SmithKline Beecham Clinical Labs (Now Quest Dx). So I was surprised that he was unable to provide additional data when Abbott and Quest asked for it. At that very moment, these two unbelievable opportunities vanished.
