I don't see anything other than a lot of promotion for this test. I would be talking to my son's dermatologist about this, though. If it's factual, like the description on the manufacturer's home page, it may be worth the $300 that I keep seeing mentioned.
Still, I'd go by my doctor, whether it is worth it or not. According to the company's page, only doctors can get and submit the test. From what I see on their site, only California, Ohio and Florida are listed as states having doctors with the tests.
