Hi Pasayten. Thanks for the heads up on this development. We can only hope that it will turn out to be another weapon against the daemon we call cancer.

This is very interesting...Two years ago, a company called Health Discovery Corp developed a test called the "Four Gene Signature urine test" that can tell, from a simple urine test, if a man has PC or not. Initially, it was used in conjunction with a PSA test to determine if an abnormally high PSA number was caused by cancer..Then they discovered the test was so sensitive it could detect PC much earlier than PSA could and therefore could be used as a screening test all by itself...Trials were held and the test quickly won FDA approval. Health Discovery Corp. (a small penny stock bio-tech company) licensed the rights to the test to both Abbott labs and Quest labs.

So far, neither of these companies have made any effort to market the test...

Fairwind ....

That is an amazing story.

As a business owner, I'm all for free enterprise, but there are times I really do wonder about corporate responsibility.


Thanks for sharing this.

I tried contacting all three companies..Only Quest replied..They actually took the time to find me and call me on the phone..They freely admitted they held the rights to perform the test but developing it was a back-burner issue at the moment. They had other pressing projects that they felt were more important...

Personally, I suspect there is a lot going on backstage..As Pasayten noted, other labs are developing their own tests and may try to avoid Health Discovery's patents..I'm just guessing, but this bio-tech stuff is a dog eat dog business...It's funny these two tests have exactly the same name..

Hmm. If the test were really good, not only does it put the PSA test out of business, it takes away a lot of business from surgeons and radiologists. So what do they do?

No, I'm being too cynical...right?

Anytime you change the Status Quo, big waves can be generated. Millions of PSA tests are performed every year at a cost of $75-$150 each..Globally, the number is staggering..Five BILLION dollars in the U.S. alone...

The Four Gene Signature Urine Test has the potential to make routine PSA testing obsolete..

Anytime you try to change a revenue stream like that, you can expect heavy resistance.

One thing I have not been able to find out, the cost and time requirement to perform one of these tests..If the cost is prohibitive or the time factor is long, or both, that would take some of the rosy glow off this new diagnostic tool...

Getting a diagnostic test approved by the FDA, especially a non invasive urine test, is a simple matter compared to getting a new drug approved..I believe they have obtained this approval. The two labs, Abbott and Quest need to develop the actual commercial test procedure and have it approved before it is offered to the medical community..

I did stumble across this ...
