Diabetes Diagnosis

Question 1

list the four criteria which can be used to diagnosis diabetes

Answer 1

fasting blood glucose > 7 mmol/L
random blood glucose > 11.1 mmol/L
blood glucose > 11.1 mmol/L after OGTT
HbA1c > 48 mmol/mol

Question 2

what is the range of HbA1c values that encompasses “prediabetes”?

Answer 2

42-47 mmol/mol

Question 3

what range of values is acceptable for blood glucose before meals in a type 1 diabetic?

Answer 3

4 to 7 mmol/L

Question 4

what range of values is acceptable for blood glucose before meals in a type 2 diabetic?

Answer 4

4 to 7 mmol/L

Question 5

what range of values is acceptable for blood glucose at least 90 minutes after meals in a type 1 diabetic?

Answer 5

5 to 9 mmol/L

Question 6

what range of values is acceptable at least 90 minutes after meals in a type 2 diabetic?

Answer 6

under 8.5 mmol/L

Question 7

what range of values is acceptable upon waking in a type 1 diabetic?

Answer 7

5 to 7 mmol/L

Question 8

what target of HbA1c should be aimed for in type 2 diabetics controlled with metformin?

Answer 8

< 48 mmol/mol

Question 9

what target of HbA1c should be aimed for in type 2 diabetics controlled with sulphonylureas?

Answer 9

< 53 mmol/mol (more leeway due to risk of hypoglycaemia)

Question 10

what is a normal level to find in a random plasma glucose test?

Answer 10

< 11.1 mmol/L
(takes into account wide range of factors that could result in a non-diabetic having blood sugar up to this value when randomly tested)

Question 11

what is a normal level to find in a fasting plasma glucose test?

Answer 11

< 5.5 mmol/L

Question 12

what is a normal level to find in a 2 hour OGTT plasma glucose?

Answer 12

< 7.8 mmol/L

Question 13

what level of fasting blood glucose is classified as prediabetes?

Answer 13

5.5 to 6.9 mmol/L

“impaired fasting glucose”

Question 14

what level of blood glucose post 2 hour OGTT is classified as prediabetes?

Answer 14

7.8 to 11.0 mmol/L

“impaired glucose tolerance”
