can the use of phenibut affect CDT blood tests?

I am not sure what the point is in this question, or that it relates to the UK because Phenibut is not common here....
It may have a similar effect on the brain, but that is not what is being tested, CDT is a marker that indicates damage to the liver due to alcohol abuse, or a medical condition so serious that the person might well need hospitalisation, it is not a check oh how the brain is / has been affected by other substances.
