Them with sonn 7 and tea and lots of water. Will it still show up?

That is discussed all the time.
Google!!

Of course it depends on how much you drank. And on how many enzymes you have in your body. There is no save way of calculating as every body is different. But average calculations are all over the internet! They all tell you a diffenrent answer, as they are not exact. There is no exact way. The different answers are as exact as it gets!
The savest way to know it better, would be to buy a measure tool and check it yourself as soon as possible after you got checked. Then you know if you have a problem or not.
Otherwise just don't worry and get ready for the case it will show up.
