The GCDx "Lung Cancer Test" is DR-70 (aka Onko-Sure)

If you want to read a VERY interesting history of DR-70 and GCDx, read the SEC filings and PR's for RXPC (nee AMDL).

DR-70 is off patent. UNI Pharma and others are trying to sell it in Asia. GCDx is trying to sell it in the USA over the internet without FDA clearance.

And the most recent Officers of the now defunct Radient Pharmaceuticals are trying to sell it in Hong Kong -- their new company is called "Cancer Screen Technologies."

Unfortunately, you can't go to CSTamdl.com using an American ISP (Error 403 Access Denied) because they blocked all American ISP's from accessing that website after we talked about it too much on the message board. You can get to that website if you use a free European or Asian proxy though.

Everyone claims to have "developed" this test themselves, claiming it to be "proprietary," but in fact we don't even know who developed it. The "70" part of the name stands for the year 1970 when it was created. AMDL (changed to RXPC) bought it around 1995 and hyped it for 20 years until they finally dissolved.

The test is NOT specifically a "lung cancer test." It detects FDP's (fibrin degradation products) in blood which may or may not indicate cancer, but here's the rub" a positive DR-70 test does not tell a doctor where in the body to look for the cancer. The specificity is therefore too low for a screener. GCDx is targeting smokers and former smokers to raise the specificity, assuming that if a smoker or former smoker has cancer, it is probably lung cancer.

The medical community and international Governments never embraced the test. Near the end, Radient promised $10 million revenues in India in one year and delivered basically zero revenues in India. DD on Guar Diagno will reveal that story.

Good luck to all.
