Pangare does it always mean brown?

Nope, your correct. We are not saying that only browns can have it, other colours do too.

This lab that test for brown - has their work been at least peer reviewed by ones who have no connection to them? If not and they are not willing to share the information - I question how legit the test is.

I think they are a very reptuable testing site. Why wouldnt they be I mean they did foot the bill to study and devolop the test and skills to get to the bottom of the brown stuff its no different than someone putting a patent on something the others havent contributed to their discovery so why should they share? After all it still is a buisness and buisness's ultimatly are out to make money.

I wasnt suggesting that it just seems alot of smokey black horses are labeled and registered brown because they have it.

Yes it is a business but also a science based business. There are a lot of scientific studies out there that reputable companies foot the bill for that fall apart under the scrutiny of peers. That is why peer reviews are conducted - to ensure the methodology and science is sound. If this company is not utilizing peer reviews and there is not a single lab other lab out there that can verify or negate the results - How do you as a customer know they are even really testing for it?

Funny that you compare it to patents. Patents reveal all the information, it just prevents other companies from using it. So anyone wanting to know the method is valid can pull and read the patent even if they can't re-check the results with a different company.

If you recall what I said before, you will be aware that black is not affected by pangare. So it is therefore impossible for these horses to be labelled as brown due to pangare, as their coat is not being changed by it. Pangare does not affect black hair, it's as simple as that.
