This evidence could be admitted, but Ms. Brunelle would not testify that your blood alcohol concentration was lower than 0.08. I suppose that you would agree on her testimony with regard to how much you had drunk, but a toxicologist would have to do the calculation based on your weight, the time it took you to drink your five glasses of alcohol, and so on.
It will still be possible to provide evidence on consumption, but if the operator has not made a mistake and the machine was not defective, it will have to corroborate the fact that your blood alcohol level was lower than 0.08 when you were driving.
