None of this argues against the company in the future, but for now, it's a long term risky investment that may pay off later, and better to keep an eye on than pony up an investment, right now. Follow the clinical science....when clinical studies show a value, then buy it. AFTER ACS guidelines include this technology and Medicare reimbursement is more assured, it'll be a play.
There's little doubt the science is intriguing. However, the issues of clinical relevance haven't been established. If an abnormality is found here, colonoscopy must be done, so unless an improvement in outcome can be demonstrated in clinical trials of this plus colonoscopy vs. scheduled colonoscopy alone, there'll be an added cost, and an inhibition to use.
