The excessive sugar levels present in the body result in attachment of the sugar to hemoglobin leading to the development of a layer of sugar on it. Red blood cells normally tend to thrive in the bloodstream for around 120 days. Thus the hemoglobin A1c range test can be used to detect the levels of blood sugar occurring in the body for almost the past 3 months. A hemoglobin A1c range test is considered as a better and more consistent test as compared to the normal monitoring of glucose conducted at one’s home.
