I agree with the point you are making. In the spirit of agreement, I would suggest that the right question is "what is it about your relative's blood test that you specifically want to bring to the attention of the NSA, government, contractors, and lobbyists."
Privacy should be the default state and expectation, and disclosure should be by exception when necessary, for exactly the reasons outlined in your post. The argument that privacy only matters if you have something to hide conceals a number of assumptions, and misses the fact that one doesn't know what one might one day wish one had hidden.
