Glycosylated Haemoglobin Flashcards
1
Q
How often should HbA1C be checked?
A
Every 3-6 months until stable and then every 6 months
2
Q
Over what kind of window of time/time period does the HbA1C reflect?
A
Typically: a 3 month period
BUT recent evidence shows it reflects the last 2-4 weeks.
3
Q
How do you calculate the average plasma glucose from %HbA1C?
A
( 2 x % ) - 4.5
(e.g. HbA1c = 5%)
THEREFORE (2 x 5) - 4.5 = 5.5mmol/l is the average plasma glucose.
4
Q
What is the IFCC-HbA1c equivalent for an HbA1C of 6%?
A
42 mmol/mol
(Just subtract 2 from the % and you are in the approximate ballpark e.g. 6-2 = 4)
5
Q
What is the IFCC-HbA1c equivalent for an HbA1C of 7%?
A
53 mmol/mol
6
Q
What is the IFCC-HbA1c equivalent for an HbA1C of 8%?
A
64mmol/mol
7
Q
What is the IFCC-HbA1c equivalent for an HbA1C of 9%?
A
75 mmol/mol
