Description

Technical Field

[0001] The invention relates to the technical field of medical saccharification analysis, in particular to a test tube rack circulation device. Background Art

[0002] Glycated hemoglobin is the product of the combination of hemoglobin in red blood cells in human blood and blood sugar. The English code name of glycated hemoglobin is HbA1c. The glycated hemoglobin test can usually reflect the patient's blood sugar control in the past 8 to 12 weeks. The combination of blood sugar and hemoglobin to generate glycated hemoglobin is an irreversible reaction and is proportional to the blood sugar concentration. It lasts for about 120 days, so the blood sugar concentration before 120 days can be observed. The glycated hemoglobin analyzer is an instrument that can best reflect the degree of hemoglobin binding to glucose when measuring HbA1c. Glycated hemoglobin HbA1c is a good indicator of the degree of disease control in diabetic patients and can reflect the staged blood sugar level. Glycated hemoglobin HbA1c is an effective detection indicator for diabetes screening, diagnosis, blood sugar control, and efficacy assessment, and has been widely used in clinical practice. In the existing technical field, in order to meet market demand and improve detection efficiency, it is ideal for the glycated hemoglobin analyzer to detect more than 100 samples at a time.
