Don't be so quick to dismiss. It sounds odd and offensive to western sensibilities but there are reasons why it could be genuine. As mentioned earlier in the thread, there are so many micronutrients in the blood stream that some deficiencies might not show up on a panel.

What amuses me about Hacker News: someone being sceptical about 'vampires' is met with responses like you see in this thread. Don't be so dismissive! Don't call them crazy! They may have a condition that doesn't show up on tests!

But just question the long term safety of nuclear reactors built on fault lines, or suggest anyone may have got cancer from radiation exposure, ever, and its just a wall of incredulity. Rubbish! Where's your proof! All the pro-nuclear science is beyond reproach!

Call me old fashioned, but these people are probably crazy, and radiation is probably dangerous. There's no bias quite like Hacker News bias...

I'm just now seeing this. I'll give you the benefit of the doubt that you weren't trying to put words in my mouth with the nuclear reactor comment. I've made no such assertions in the past and don't really have an opinion on the matter.

However, I think it's pretty easy to see how someone's prejudices/preconceptions could skew someone's opinion of the article. If the article was about cockroaches rather than human blood, I would have the same opinion.
