Glycosylated Hemoglobin Point of testing kits
Hemoglobin A1c (HbA1c) Kit (Immunofluorescence) is mainly for the in vitro quantitative determination of Hemoglobin A1c (HbA1c) content in human serum. Hemoglobin A1c (HbA1c) is a combination of hemoglobin and blood sugar in human blood, and is positively related to blood sugar concentration. The combination is irreversible. HbA1c disappears with the death of red blood cells (the life span of red blood cell is around 120 days), and therefore, it can reflect the average blood sugar levels in the first 2-3 months of blood collection. The increase of HbA1c can change the affinity of erythrocyte to oxygen, making tissues and cells anoxia, accelerating the formation of cardiovascular complications; can cause the thickening of glomerular basal membrane, inducing diabetic nephropathy (DN); can cause the increase of blood lipids and blood viscosity, and is an important factor in the occurrence of cardiovascular disease. It can also significantly reduce the compliance of red blood cells (that is, the ability to deform), making it difficult for red blood cells to penetrate the walls of blood vessels and bring oxygen into the tissue. Therefore, it is of great significance to monitor HbA1c for disease control in diabetic patients, the prediction of complications, and the screening of diabetic patients. The common detection methods in Clinic are Turbidity method, immunofluorescence method, enzymatic method and high performance liquid chromatography (HPLC) method.
The assay is a double-antibody sandwich immunoassay for quantitative determination of HbA1c concentration based on immunofluorescence technology. The sample droplets to be measured were added to the sample hole of the detection card, and under chromatography, the sample and binding pad were coated with the fluorescent latex of hemoglobin monoclonal antibody I, and the reaction complex spread forward along the nitric acid fiber membrane. The HbA1c monoclonal antibody and hemoglobin monoclonal antibody II, which were fixed on the nitric acid fiber membrane detection line, were captured. The more HbA1c in the sample, the more complexes were stored on the test line, and the intensity of the fluorescent antibody signal reflected the number of HbA1c captured. The concentration of HbA1c in the sample can be determined by the Immunofluorescence quantitative analysis instrument produced by Norman Biological.
