So I was on Target's website and I came across this home product that takes a small blood sample and saliva sample and it'll test your free test, cortisol and TSH levels. It says it uses just a few drops of blood then you mail it off and the results are in a few days.

Has anybody used this before? Is it accurate?

They also have other tests as well on their website.
