Abstract
An improved fluorigenic, high-performance, liquid chromatography (HPLC) assay comprises reacting plasma and hemolysate samples with cyclohexanedione in the presence of ammonium ion to form a methylacridine dione fluorigenic species that is stable and exhibits high recovery values. Acetaldehyde content was determined by comparing the fluorescent peaks of the HPLC eluted band with standard peaks. Alcohol intake by the subject was detected by comparing the acetaldehyde levels to those of teetotalers.
