It is $266 through directlabs. A little pricey but I think its more definite than the culture tests, which I have done before. As an example, a list member on the curezone board was treating herself for candida for a while and not getting better. It turns out she had cryptosporidium and she beleives she picked it up from her travels. She had to tailor her treatment to the cryptosporidium and she got well.
