I believe it was a few thousand dollars for just the machine. They sent me some comparative info on their results vs traditional lab results, which were good. If you breed often enough using progesterone, it could easily be worth the price as long as it is accurate. They did offer to test my bitch if I sent them samples my next breeding so I could compare to lab results.

I took a look back at the website. Doesn't seem they offer it anymore.

do a google search. There are a few different test options available. Elisa and so on.

Which one of these is the one to order??
