alcohol level blood test required to get on transplant list

My brother goes to a free clinic for health issues.  He needs to get on a liver transplant waiting list.  In order to get his one year sobriety wait time started, he requires blood test to detect any alcohol levels or not in his blood.  We need the specific name of the blood test, the procedure and/or the substances that the blood is tested for, whichever applies.  This information will allow the free clinic to request the test for him and a transplant center to acknowlege the test.  Hope to hear from someone soon so that we can move forward.  He's been discharged from the hospital for 2 months and is alcohol free.  Thanks.

most centers assess routine toxicology screens, in which alcohol is a usual component. they can also check a separate alcohol level.
