The question is not clear.



Are you after a method of determining to level of GHB in a drink?

I don't know a method (probably would be GC, HPLC based). But to calculate the % in the sample you would work out the the amount in the sample and dive by the total weight of sample expressed as a percentage.



Or are you after the amount of material that a test method recovers from a solution. To do this you would prepare a known concentrate of a solution of GHB. You would then analyse the solution via your chosen test method. Work out the amount of GHB recovered and express as a percentage of known added GHB in the sample.
