Gasoline Testing?

I am wondering if there is a place I can send a sample of it and get it tested to make sure it is ok. I don't want to just use it and I don't want to just throw it in my H2 3 gallons at a time to get rid of it either.
Once I have the turbos on the car I would like to be able to use some of it for my initial tuning, for safety reasons.
Please advise.
TIA
