Abstract: A method is provided for detecting carbohydrate-deficient glycoproteins in samples taken from subjects with metabolic disorders, such as alcohol abuse and subjects who display a syndrome of carrying abnormal levels of carbohydrate deficient glycoproteins. The method involves steps of reglycosylating with a fluorescent-conjugate deglycosylated glycoproteins in a sample of body fluid from a subject. A further step involves fluorometric detection of fluoresceinylated carbohydrates incorporated into truncated serum glycoproteins.
