What are the limitations of traditional diagnoses of diabetes? 

Best insight from top research papers

Traditional diagnoses of diabetes have several limitations. Fasting glucose (FG) only detects 70-80% of overt diabetes and is affected by inappropriate blood sampling and intra-individual fluctuations . The oral glucose tolerance test (oGTT) is the most sensitive test but has poor reproducibility . HbA1c analysis, despite standardization, is difficult to interpret and has limited diagnostic value . Its threshold value of ≥6.5% is based on consensus rather than evidence . These traditional diagnostic methods also have pre-analytical and analytical problems, such as falsification of results and interferences . In addition, the diagnostic effort required for these methods is invasive and may lead to over- or underdiagnosis . Therefore, there is a need for fast, easy, and inexpensive diagnostic approaches for diabetes .
