Diabetes Screening (HbA1C & Fasting Sugar) in Allahabad

An HbA1c (Hemoglobin A1c) test precisely measures the percentage of sugar-coated or glycated hemoglobin in your blood. The test results represent the proportion of hemoglobin in your blood that has been glycated. 

Hemoglobin, a vital protein found in red blood cells, is responsible for transporting oxygen throughout the body. Hemoglobin A is the most abundant form of hemoglobin, and when blood sugar levels increase, a higher proportion of hemoglobin A becomes glycated. As red blood cells have a lifespan of approximately 120 days, the sugar molecules remain attached to the hemoglobin for the duration of the cell's life. Consequently, the HbA1c test offers insight into your average blood sugar levels over the past 8 to 12 weeks. 

A fasting blood sugar test measures the level of glucose in the body under overnight fasting conditions. Glucose serves as the energy currency of the body and is broken down through metabolism to produce energy. This process is controlled by hormones and enzymes in organs such as the liver and pancreas. The hormone insulin, produced by the pancreas, is responsible for regulating blood glucose levels. When these levels are high, such as after a meal, insulin is secreted to transport glucose into cells for energy production. Elevated glucose levels in the body after fasting may indicate a risk of developing prediabetes or diabetes, which can be of two types- Type 1, caused by little or no insulin production, and Type 2, caused by insulin resistance or decreased insulin production.
