Because HbA1c is not affected by short-term fluctuations in blood glucose concentrations, for example, due to meals, blood can be drawn for HbA1c testing without regard to when food was eaten. HPLC separates mixtures (for example, blood) into its various components by adding the mixtures to special liquids and passing them under pressure through columns filled with a material that separates the mixture into its different component molecules. HbA1c may be separated by charge and size from the other hemoglobin A components in blood by a procedure called high pressure (or performance) liquid chromatography (HPLC). The molecule of HbA1c also differs in size from the other components. How Is Hemoglobin A1c Measured? The test for hemoglobin A1c depends on the chemical (electrical) charge on the molecule of HbA1c, which differs from the charges on the other components of hemoglobin. HbA1c is typically measured to determine how well a type 1 or type 2 diabetes treatment plan (including medications, exercise, or dietary changes) is working. High HbA1c levels indicate poorer control of diabetes than levels in the normal range. HbA1c levels are reflective of blood glucose levels over the past six to eight weeks and do not reflect daily ups and downs of blood glucose. HbA1c also is known as glycosylated, or glycated hemoglobin. The normal range for level for hemoglobin A1c is less than 6%. Blood HbA1c levels are reflective of how well diabetes is controlled. ![]() The blood test for HbA1c level is routinely performed in people with type 1 and type 2 diabetes mellitus. Hemoglobin A1c, often abbreviated HbA1c, is a form of hemoglobin (a blood pigment that carries oxygen) that is bound to glucose. However, after 3 months of treatment, significant decline from 6.60 to 5.74 was found in HbA1c levels. Results: The mean baseline HbA1c level in anaemic patients (6.60) was significantly higher than that of controls (5.48). These values were also compared with those in the control population. HbA1c levels of them were measured both at baseline and after 3 months of treatment of iron deficiency. Methods: Fifty patients confirmed to have iron deficiency anaemia were enrolled in the study. We conducted a study to analyze the effects of iron deficiency anaemia on HbA1c levels and to assess whether treatment of iron deficiency anaemia affects HbA1c levels. However, reports on the effects of iron deficiency anaemia on HbA1c levels are inconsistent. Like blood sugar levels, HbA1c levels are also affected by presence of variant haemoglobin, haemolytic anaemia, nutritional anaemias, uremia, pregnancy and acute blood loss. Haemoglobin A1c (HbA1c) is used in diabetic patients as an index to reflect glucose levels of the previous 3 months. doi: 10.21767/2386-5180.1000123 Visit for more related articles at Annals of Clinical and Laboratory Research Abstract Background: Iron deficiency anaemia is the most common form of anaemia in India.
