"Not only would way more people happily submit to the test but the savings to the health industry of having to avoid a boatload of unnecessary colonoscopies"

Actually, this is incorrect "unnecessary colonoscopies" is driven by the false positive rate that is a function of specificity of the assay. FIT has higher specificity than ColoSTAT (96% versus 91% hence FP rates of 4% and 9% respectively).

In other words, for every 50K people screened (assuming a CRC prevalence of 0.49%) then FIT will produce ~1,800 FP / unnecessary colonoscopies but ColoSTAT will be ~4,500 unnecessary colonoscopies.
