I'd really like to know how the test works.

There was a good article on it in the NY Times today, but I only saw it in the paper edition or I'd give you a link. It was apparently a test developed for pregnant women who are having children with a different blood type. Apparently there are many different sub-types of blood, and the test can discern between the sub-types. If someone dopes with someone else's blood, it would be highly rare that the types would match exactly, and the test can pick out the difference.

I read that, and if it's an accurate representation of the test, it doesn't look good for Tyler. Apparently, under ultraviolet light, these different sub-types of red blood cells either fluoresce or not. If all red blood cells fluoresce, then it's one person's blood. If some cells fluoresce and some don't, then two people's blood. With 12 sub-types of blood, the article said the chances of 2 people having all the same types was something like one in a million.
