Home Testing kit - To see if its fake

[hardcoreSE]

Are their home testing kits to see if you have the real deal?

Or would you have to send your urine/blood to a lab to see if it was real.

[Bonaparte]

There are at home kits to check your urine, but they only cover a few compounds (and most importantly, they won't tell you if it is dosed accurately).
And they're still fairly expensive.
