Interesting, I wonder for us AFR users, if we should take water samples for ICP at least a few hours after the last dose of AFR to ensure it gets fully metabolized?

Most ICP tests don't even check for Alk (it can't be checked on ICP - they use some other formula to back into it or test it separately I believe). I wouldn't worry too much about it..plus home alk kits are pretty good, relatively speaking.

I bet @Darkxerox is right though - especially with the high quantity of AFR that was bring dosed!
