oh yeah you 're that 's a good point but at TI they before they had the testing i 've forgotten it seems seems like it 's a year ago September something like that they told us that the agency that did it was the one that did it for the government and and that of course that 's critical just as the point that you 're brought up that whoever does your testing has got to be you know have a lot of quality control that they keep track of everything they don 't make mistakes that would be terribly embarrassing
There are some drug testing agencies that make mistakes .
