it is san diego-based pathway genomics. pathway raised $40 million in its last round of fund-raising. >> it's, like, the most amazing thing. >> reporter: and raised its profile when one of its genetic tests was featured on "keeping up with the kardashians." >> mitch mulinex from pathway genomics. >> nice to see you. >> reporter: what caughture attention was the test pathway launched in september. >> introducing pathway genomics' revolutionary test-- cancer intercept, detect and monitor. >> reporter: available by physician order for as little as $299, pathway's marketing claimed it could do what others say is years away. >> cancer intercept can detect a growing tumor in the body before the patient may notice symptoms. >> reporter: a few weeks ago, we visited pathway to ask them about their claims. before we sat down with the c.e.o., jim plante, they played us that marketing video. we just watched a video upstairs. >> right.

cancer researcher at stanford. pathway cites his research as evidence their test can detect patients. >> i think we're still years away from that possibility. while we have -- >> reporter: years. >> years. that absolutely requires thousands of patients and long-term trials to prove that. >> reporter: thousands of patients, years of testing, millions of dollars. >> correct. >> reporter: and if a company isn't doing any of those three? >> then i don't think i would order that test. >> reporter: the food and drug administration tells us can considers tests like cancer intercept a major health risk. in september, the f.d.a. sent pathway genomics a letter citing concerns the test did not have adequate clinical validation and may harm the public health. pathway now has three clinical trials under way to study its liquid biopsy, but it all began after the test was already on the market. and, scott, after our interview, pathway did pull that
