Full Name: HbA1c ELISA Kit (Glycated Hemoglobin A1c)
Sample Type: Tissue Homogenates, Plasma, Serum, Biological Fluids
Sensitivity: 37.5 pg/ml
Glycated hemoglobin A1c (HbA1c) is present in people who have had diabetes for some time. Normally, as glucose leaves the cells and travels through the blood, it binds to haemoglobin before being absorbed by cells all throughout your body. The most commonly used tests to measure glycation are glycated haemoglobin and glycated albumin. This test will show haemoglobin that has bound to glucose, which can be measured in millimol per liter units. It is created by the nonenzymatic chemical reaction between glucose and the amino group on the N-terminal valine of the haemoglobin beta chain. It represents about 5% of the total HbA fraction present. This glycosylated form of haemoglobin is produced by the body following prolonged periods of hyperglycemia. It forms in response to high blood glucose levels, specifically when the pancreas cannot keep up with producing insulin.
To confirm whether a patient’s hemoglobin a1c is within normal range, they need to also obtain their fasting plasma glucose and postprandial plasma glucose levels on separate days. If these values are normal, then the HbA1c can be considered normal as well. However, if values of HbA1c are elevated it may indicate more serious problems such as dehydration, diabetes, or thyroid disease that should be investigated further. The normal reference range is 4.5-6%.
Human HbA1c ELISA kit can be used to measure amounts of glycated hemoglobin A1c (HbA1c) present is human serum, plasma, biological fluids and tissue homogenate samples.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
