Technical Field

The invention belongs to the technical field of liquid chromatography reagents, and particularly relates to a reagent matched with a glycosylated hemoglobin high-pressure liquid chromatography analyzer.

Background

L-HbA1c (abbreviation of "Labile hemoglobin A1C"), which is an aldimine compound formed by the amino group reaction of glucose with the valine residue at the β chain-N terminal of hemoglobin HbA, is an intermediate product of stable hemoglobin of S-HbA1c (stable hemoglobin A1C), and S-HbA1c (glycated hemoglobin) is a gold marker for the diagnosis and monitoring of the therapeutic effect of diabetes.

HbF (foetal haemoglobin), commonly known as fetal haemoglobin, accounts for only 0.5% of total haemoglobin in normal adults, but certain conditions such as thalassemia, persistent increase in hereditary HbF, etc. contribute to a higher HbF.

However, the existing low-pressure liquid chromatography can not completely separate HbF, L-HbA1c and HbA1c, and when some clinical samples HbF or L-HbA1c are abnormal, the measured value of HbA1c is falsely increased, so that the test result is inaccurate.
