Understanding Medical Tests Results
How to Interpret Them
This article is the first in a series dedicated to medical tests and examinations.
I recently received a medical test during my annual check-up with my Family Doctor. He knew that I had retired and wanted to have a baseline for my biological profile.
I did not complain of any symptoms nor did my physical examination show any concerns.
The test came back within normal limits except for the Hemoglobin A1c or glycosylated hemoglobin, which measures how well the level of blood sugar has been controlled in the last 3 months.
The result showed 5.7 %, which means “at risk.” The range is 5.5–5.9 %.
The normal Hb A1c test is : below 5.5 %.
The pre-diabetes range is 6.0%-6.4%.
Diabetes mellitus is equal to or above 6.5 %.
All the numbers are consistent with Canadian Guidelines.
The American Diabetic Association numbers are :
Normal blood sugar : below 5.7%.
Pre-diabetes or increased risk of diabetes : 5.7–6.4%.
Diabetes : 6.5% (48 mmol /L) or higher
