Urine test for alcohol


Question:Do you have a graph that shows the rate at which alcohol leaves the body through the urine in an alcohol test?

Answer: The urine test for measuring alcoholemia or blood alcohol is used only very rarely nowadays, on account of its being more time-consuming and less accurate than tests via blood samples or exhaled air. Alcohol usually leaves the body at the average rate of 0.15 g/h. However, it should be pointed out that this value may differ considerably from one person to the next and will also depend on the circumstances of the drinking episode. The concentration in the urine is generally assumed to be 1.3 times greater than that in the blood at the time of testing.
