Urine Organic Acid Testing - Which lab to use?

[Guest guest]

I would like to get an updated urine OAT done for my son. I used Dr.

Shaw's lab, Great Plains, the first time but would like some input

whethere there is a more preferrable lab to use. Also, I recently

tried to access Great Plains website, but received a " this page not

available " and have not been able to access them since, even though I

had been able to do so in the past.

Which lab should I use for urine OAT?

Does anyone have a website for Great Plains Labs?

Thank you.
