What is the diagnostic potential of HbA1c?

Diagnostic Potentials of HbA1c. The ADA has recently recommended HbA1c with a cut-point ≥6.5% for diagnosing diabetes as an alternative to fasting plasma glucose (FPG ≥7.0 mmol/L)-based criteria. The levels of HbA1c are strongly correlated with FPG (Fig.

How does measuring HbA1c work?

Measuring HbA1c levels instantly provides a bigger picture view, kind of like an average of your blood sugar levels over the past 3 months. It’s usually taken from your regular arm blood test rather than the finger prick. This HbA1c chart shows how the different tests correlate with one another.

67. Pradhan AD, Rifai N, Buring JE, Ridker PM. HbA1c predicts diabetes but not cardiovascular disease in non-diabetic women. Am J Med. 2007;120:720–7. [PMC free article][PubMed] [Google Scholar] 68.

How is HbA1c reported?

Your HbA1c (also known as A1c or glycated haemoglobin) can give a general gauge of your diabetes management, because it provides an average blood glucose level over the past few months. Unlike the finger prick test that you do for yourself, which are reported as mmol/l, HbA1c is reported as a mmol/mol.

What diagnosis covers HbA1c?

“HbA1c testing should be performed at least biannually in all patients and quarterly for patients whose therapy has changed or who are not meeting treatment goals.” “HbA1c may be used for the diagnosis of diabetes, with values >6.5% being diagnostic.

Why is HBA1C lowered?

HbA1c is physiologically lowered by 0.5% due to expansion of red blood cell (RBC) mass and recruitment of new immature RBCs. Diffusion of glucose through the RBC membrane increases with age, so the build-up of newer RBCs lowers HbA1c values in pregnancy.
