Decoding HbA1c Test for Blood Sugar
What is considered a ‘normal reading’ for the HbA1c calculator?
Recommended HbA1c readings fall within the reference range of 6.5 to 7%. This implies that for every 100 red blood cells, 6-7 cells have glucose attached to them. Mean blood sugar levels can be better understood from the following table.
|HbA1c-Average Blood Glucose Reading|
|3-4||2-4||36-72||Extremely low to low blood sugar|
|4.5-5||5-6||90-108||Normal range for non-diabetics (pre-prandial)|
|5.5 - 6||7 – 8||126 - 144||Normal post-prandial in non-diabetics|
|6.5 – 7||9 - 10||162 - 180||Maximum post-prandial in non-diabetics|
|6.5 – 7.5||9 – 11||162 - 198||High, even for diabetics|
|7.5 – 9.5||11 – 15||198 - 270||Indicates to poorly controlled bG|
|12.5 - 25||20 - 25||360 - 450||Extremely high|
|> 19||33 or > 33||> 594||High possibility of serious electrolyte imbalance!!|

Rough Glucose Conversions:
mmol/L → mg/dL : Multiply by 18
mg/dL → mmol/L: Divide by 18 (or multiply by 0.055)
Or, you could simply use Medindia’s Blood Sugar Converter available at or our HbA1c1c1c(A1c) Calculator for Blood Glucose.
AdvertisementSince glucose binds slowly to Hemoglobin A (and decomposes at about the same rate), the HbA1c count is a good indicator of average blood glucose over a period of time. The American Diabetes Association recommends an A1c of 7% (implying 7 cells out of every 100 have an appendage of blood glucose) or lower.
But deciding upon a generalized “perfect blood sugar” value is impossible as this varies from person to person.
Instruments to Measure HbA1c1c
The following instruments are used to measure glycosylated hemoglobin.
a) Conventional procedures like Immunoturbidimetric methods (out-dated and inaccurate).
b) Micromat™ which provides on-the-spot (in 5 minutes) and accurate results. Recommended for diabetologists and small laboratories.
Advertisementc) Diastat™ is the ideal HbA1c monitoring device. It is used in pathological laboratories and hospitals.
d) The VARIANT™ Hemoglobin Testing System is a state-of-the-art contraption which provides automated diabetes monitoring, beta- thalassemia, and screening for hemoglobinopathy and sickle cell disease.
