I think the reason most people send it to the U.S. is that if you get the first-tier positive, it then goes to your second-tier positive, but the Americans will give you the banding pattern.
There are supposed to be five out of 10 bands that have to be positive, but that already exists at the national lab. They already know, if it's positive, which one of those five is positive, so a really quick thing to do would be to release that to the family doctor and say that this individual maybe only has four of 10, but if we know, for example, that this person lives in B.C, they got four out of 10, and they're sick, then maybe for that individual it's worth trying the treatment. That would be a really quick way to deal with it: to release all the information they have.
I believe that even now they've stopped giving the C6 positives. Now, in order to get the word “positive”, you have to be positive for the C6 and for the Western blot, whereas if you said, “positive for C6”, that's one piece of information, so it's positive for the Western blot and the particular banding pattern.
