I forget that's another test you have to pay for (in Canada, there's no charge for an insulin test). Good luck and let us know what you think (as well as your results).

Sunski, thanks for further clarifying the search info. I was being very hastey. The beauty of the saliva test is its simplicity. Good luck!

Msk, you're absolutely right. Some sites on the net won't sell the kits to non-physicians, but there are others that sell the kits to the public b/c the lab has someone read the results for you. The latter is perfectly suited to someone following SP.
