It is. As someone who's been through the pain of this exact lab fuck up (though from traditional, not theranos equipment I would assume) being mis-diagnosed and starting medication for this condition incorrectly can be terrible. The cure for Hyperthyroidism is so easy, and the condition so common, that people forget what the effects of the extremes of the conditions are.

There are lots of industries you can disrupt, or fail fast at, but lab testing isn't one of them.
