Blood Drug Testing

Does this drug test work?

I used this home drug test: http://hocks.com/hocks-healthcare/hocks-product/A211383.html It came up with two lines which is supposed to indicate negative. Although the control line was a lot darker then the THC line(I don't think that matters though?). I was just wondering how accurate it is on whether or not its negative. Has anyone used this and had it be wrong? Thanks!
