Saliva testing for hormone levels?

I wouldn't think that testing saliva would be as accurate as blood tests, but since it's cheaper and easier... is the saliva testing accurate enough to guage your hormone levels?

Here's the place that sells the saliva testing:

Has anyone heard of them before?

I don't think it would be accurate. Hell, even with blood, the levels can change throughout the day.

It just seems too easy......like trandermal cycles compared to injecting. But I could be wrong.

I am not even sure why this would be helpful. I guess it would be interesting to see where levels were, but I don't think I would change dosages in a cycle or anything like that based on the results.

This system uses technology developed where I work, and is very interesting..

I don't see how they could possibly detect hormones at all in saliva, and even if they did, I doubt it would be accurate. The page says, "Saliva hormones are identical with the hormone level measured in blood and are considered biologically more important than total blood levels." If that were true, doctors would not be doing blood tests. I understand how this kind of test functions for other drug use, but IMO, I doubt hormones would show up in your saliva in any measureable amount.
