GLUQUANT A1C

Overview of HbA1c 

Diabetes is a metabolic disorder that shoots up the blood sugar level in human body. It has huge prevalence all over the globe. Polydipsia (excessive thirst),Polyuria (Frequent Urination) & Polyphagia (constant hunger) these are the major symptoms of diabetes. There are 2 types of diabetes: Type 1 (Body doesn't produce enough insulin) & Type 2 diabetes (body cannot use insulin properly), type 2 diabetes can be hereditary. Early detection is possible by regular interval monitoring of blood sugar level. 


Nowaday,s it is recommended glycated hemoglobin (HbA1c) as a possible substitute to fasting blood glucose for diagnosis of diabetes. Glycated hemoglobin or glycosylated hemoglobin (hemoglobin A1c, HbA1c, A1C, or Hb1c; sometimes also HbA1c) is a form of hemoglobin that is measured primarily to identify the average plasma glucose concentration over prolonged periods of time.When blood glucose levels are high, glucose molecules attach to the hemoglobin in RBCs. The longer hyperglycemia occurs in blood, the more glucose binds to red blood cell and the higher the glycosylated hemoglobin.


Once a hemoglobin molecule is glycated, it remains that way. A buildup of glycated hemoglobin within the red cell, therefore, reflects the average level of glucose to which the cell has been exposed during its life-cycle. Measuring glycated hemoglobin assesses the effectiveness of therapy by monitoring long-term serum glucose regulation. 

The HbA1c level is proportional to average blood glucose concentration over the previous four weeks to three months. Some researchers state that the major proportion of its value is weighted toward the most recent 2 to 4 weeks.


In diabetes mellitus, higher amounts of glycated hemoglobin, indicating poorer control of blood glucose levels, have been associated with cardiovascular disease, nephropathy, and retinopathy. Monitoring HbA1c in type 1 diabetic patients may improve outcomes.

Significance of HbA1c: To assess the long term glycemic control in diabetic patients, To predict risk for development of chronic complications in diabetes, To guide treatment of diabetes more effectively

The results of HbA1c measurement are expressed in percentage, indicating the ratio of hemoglobin combined with glucose to the total hemoglobin. The HbA1c level of non diabetic patient is 4-6%.


Many studies have shown that if the diabetic patients could lower the HbA1c level to below 8%, the incidence of the diabetes complications will be lowered greatly. If the HbA1c level is higher than 9%, it means the blood glucose of the patient is continuously high, and complications, such as diabetic nephropathy, atherosclerosis and cataract, even acute complications, such as diabetic ketoacidosis, may come up.

HbA1c analyzer

GluQuant A1c is a benchtop fully automated HbA1c analyzer based on Ion Exchange Chromatography with HPLC principle. HPLC remains the GOLD STANDARD method for estimation of HbA1c and is used as reference to calibrate other HbA1c measuring technologies. 

Merilyzer GluQuantA1c diabetes machine is a fully automated HbA1c analyzer based on Ion Exchange Chromatography with HPLC principle.

Merilyzer GluQuantA1c is an automatic instrument used to measure the ratio of glycated hemoglobin in blood, characterized of small sampling, fast analysis, etc.

The analyzer can analyze the whole blood/diluted sample, display the peak map of glycated and non-glycatedhemoglobins in the sample, and figure out %A1ab, %F, %La1c, %A1c and %A0 by the area ratio of peak shape.

This diabetes machine gives result in NGSP unit, Reference Value (NGSP Unit)
Healthy Population 4.0%~6.0 %
Acceptable Range 6.0%~8.0%
Diabetic Patients >8.0%, It is recommended that each laboratory establish its own reference values according to the characteristics of population.

Merilyzer GluQuantA1c Linear range of HbA1c is 4%-17%, with correlation coefficient r≥0.99.

Benefits

GluQuant A1c - HPLC Analyzer

Indication:

  • High levels of HbA1c can indicate poor treatment compliance and an increased risk of complications such as kidney failure, nerve damage, heart disease and eye disease.
  • Determination of HbA1c is important in the longer term care of a diabetic patient and in the monitoring of pregnancy related diabetes and therapeutic interventions.
  • Regular monitoring 3 or 4 times a year is recommended and can lead to successful changes in diabetes treatment and improved control.
