GLUCOSE LEVELS Calculate how much higher the blood
sugar (glucose) level of a diabetic is before breakfast
when compared to a nondiabetic before breakfast.
Express this number as a percentage of the nondiabetic
sugar level before breakfast.
3.5
Diabetic
3.0
- Nondiabetic
2.5
2.0
1.5
1.0
Solution
0.5
1 This is what you know:
• nondiabetic blood
1 2 34 5 6
sugar at 0 h = 0.85 g
sugar/L blood
Hours after breakfast
• diabetic blood sugar at 0 h = 1.8 g sugar/L blood
2 This is what you need
to find out:
How much higher is the glucose level of a diabetic person
than that of a nondiabetic person before breakfast?
• Find the difference in glucose levels:
1.8 g/L - 0.85 g/L = 0.95 g/L
• Use this equation:
3 This is the procedure
you need to use:
%3D
difference between values
nondiabetic value
X 100% =
percent
difference
• Substitute in the known values:
0.95
X 100% = 112%
0.85
• Before breakfast, a diabetic's blood sugar is about
112 percent higher than that of a nondiabetic.
4 Check your answer:
Change 112% to a decimal then multiply it by 0.85. You
should
get 0.95.
Practice Problems
1. Express as a percentage how much higher the blood sugar value is for a diabetic person
compared to a nondiabetic person 1 h after breakfast.
2. Express as a percentage how much higher the blood sugar value is for a diabetic
person compared to a nondiabetic person 3 h and 6 h after breakfast.
