OK, so legislate the need for accuracy through licensing, etc -- I don't see how a doctor's order would make the test more accurate.

Part of the problem is that these tests aren't for specific diseases, and really can't be made more accurate. Nobody knows what these genetic association studies mean on a clinical level. For example, if a woman is found to have a SNP marker that is associated with breast cancer, you might conclude that she shouldn't take birth control, since that raises the risk. But what if she also has a marker associated with ovarian cancer? Hormone therapy helps with that. What then? There are dozens of stories like this one, and even doctors are over their heads when it comes to this stuff. There's absolutely no chance that a layperson is going to be able to interpret the data of such a clinically dubious test. It may not be the best idea to enforce a doctor's order for these things, but there's a legitimate argument to be made, and it goes well beyond a simplistic interpretation of personal liberty. If enough people shell out for these scans, it's going to cause panic, over-medication and over-utilization of the medical system. Again, it's a question of public health. But don't take my word for it...here's a great editorial with some even better examples of the problems: http://seattletimes.nwsource.com/html/opinion/2004425391_geneticsop20.html http://seattletimes.nwsource.com/html/opinion/2004425391_gen...

  The tests for various SNP markers can be verified as accurate or not. The interpretation of the presence of a given marker may be up for debate, and these companies should not be making exaggerated claims about the ability of these tests to predict a person's risks for specific diseases. In short, if something should be regulated here, it's the claims these companies make about the value of the tests.

    They make little or no claim about the value of the tests. The argument against what they are doing is saying that offering any information about disease risk is an inherently medical topic.

  Attitudes like yours are a large part of what is wrong with the world - 'People might makes mistakes so don't allow them to make decisions. In fact don't even allow them to have information because it might make them want to make decisions'. You'd fit in really well with the Roman Catholic orthodoxy in the time of the reformation - trying to forbid people from printing bibles.

    The problem is not saying your DNA looks like this GTTAT... or you have version 27 of ___. The problem is saying you have X, Y, Z markers which increases your risk for A, B, and C which is a medical diagnosis. I don't have a problem if they give you all the data but linking DNA with risk not something individuals are capable of evaluating at this point in time.

      It's not a diagnosis. It's basically a search engine where the queries are DNA and the results are a summary of the academic literature related to specific sequences. If these tests should be outlawed, then so should any site that allows you to enter in symptoms to see what might be wrong with you.

  The linked article gives a good justification for not purchasing such tests to begin with, but it doesn't suggest that they should be outlawed. You suggest that someone will get these tests done, then go to their doctor and ask what they can do about the results. I see absolutely no problem with that. You say that even doctors don't know how to evaluate conflicting results from these tests, but why is that a problem? Someone will go to their doctor and their doctor will tell them the test is meaningless. Even if people who got these tests done overused the healthcare system, it should still be allowed. These are private doctors and private insurance plans. Perhaps Medicare shouldn't cover further evaluations that are the result of such a test. I fear for the future of our society when the belief that one should be able to obtain any desired information about oneself is referred to as a "simplistic interpretation of personal liberty". Please don't vote.
