ABSTRACT
Objective To assess the efficiency of an iontophoresis-based screening method (EZSCAN) in the detection of impaired glucose tolerance (IGT),diabetes mellitus (DM) and metabolic syndrome (MS).Methods A total of 166 subjects without medical history of dysglycaemia underwent fasting plasma glucose (FPG) and HbA1c measurement and oral glucose tolerance test (OGTT) by using traditional or EZSCAN method.Variance analysis (GLM),SNK analysis,logistic regression analysis,and ROC analysis were used to evaluate the diagnostic value of those screening techniques.Results DM,IGT,normal glucose tolerance (NGT) +MS,and NGT were found in 4,26,25 or 111 participants,respectively.For traditional test,FPG of 7.0 mmol/L showed a lower sensitivity to detect DM (0%).The sensitivity of EZSCAN to detect DM,IGT or MS was 50%,77% and 64%,respectively.Conclusions FPG may have lower sensitivity to detect DM,although EZSCAN could show higher sensitivity to detect IGT,DM,and MS.
