摘要
Glycat ed hemoglobin(HbAlc)has been increasingly accepted as the gold standard for diabetesmonit oring.In this study,Raman spect roso was tentatively emplo yed for human hemoglobin(b)bioc hemical analysis aimed at de veloping a a simple blood test for diabetes monitoring.Ramanspectroscopy measurementsperformed oWereglobimples of patients(n=39)withconfirmed diabetes and healthyvolulhetentatiassignments of the measuredRaman bands were perfortwogegroups.Meanwhile,principal componentaminant analysis(LDA)wereemployed to develop effective weell1ormal controls andpatients with diabetes.Asat wo groups demonstrated twodistinct clust ers with a sensitivity and specificity d 73%,respectively.Then the effectiveness of the diagnostic algorithm based onechnique was confirmed by receiveroperating characteristic(ROC)curve.The area under the ROC curve was 0.92,indicating a good diagnostic result.In summary,our preliminary results demonstrate that proposing Raman spectroscopy can provide a significant potential for the noninvasive detection of diabetes.
