I don't know anything abt that since I don't drink=no DUI, but if you think theoritically, it doesn't make sense(for me).
The breathelizer uses ur breathe to analyze the alcohol level and this breathe comes from your resp system. Resp 101 We breathe oxygen till it passes the alveoli and diffuses in the capillaries(where the blood is mixed with alcohol). During this diffusion between o2 and co2, it makes the alcohol level drop because some of it might have been absorb by the renal system of the body before it reaches the capillaries in the lung.
so with this theory even if u took it simultaneously or at the later time, the blood will have more alcohol level than the breathe. And even that if we decided to take a blood test, don't we suppose to be refered to the hospital?
I hope my explaination make sense.
