K. Grimsrud et E. Sundrehagen, UNITS, MG L OR PERCENT-CDT FOR DETECTION OF HARMFUL ALCOHOL-CONSUMPTION - COMMENTARY/, Addiction biology, 2(2), 1997, pp. 229-231
Recent studies have demonstrated that the diagnostic performance of CD
T measurements is influenced by variations in total transferrin concen
tration. Improved specificity is obtained with relative values, either
%CDT or units CDT per total transferrin concentration. Whether relati
ve or absolute values are used, confirmatory methods by HPLC or IEF sh
ould be available, and definition of the CDT values and correlation to
HPLC or IEF should be given.
