Question

which lab marker is a \yellow flag\ for alcoholism?
ldh
cpk
alt
ggtp

Explanation:

Gamma - glutamyl transpeptidase (GGTP) is often elevated in individuals with alcoholism. It is a sensitive marker for alcohol - related liver damage and can be an early "yellow flag" for alcoholism. LDH is a marker for tissue damage in general, CPK is related to muscle damage, and ALT is a liver enzyme but not as specific as GGTP for alcoholism.

Answer:

D. GGTP
