how long if u have a drink would it show up on a blood test as I had a drink Saturday gone an I have a blood test Thursday to get ma licence back
Hi. For the standard blood test for alcohol it would have been out of your system within 24 hours after the drink. If you're referring to the ETG test that would be negative after about 40 hours. So either way you should pass on Thursday assuming you don't consume any more alcohol until then
