A blood glucose test measures the amount of glucose in a person's blood and is used to screen for and diagnose prediabetes and diabetes. There are several types of blood glucose tests, including fasting blood sugar tests, oral glucose tolerance tests, and A1c tests. Normal blood glucose levels are below 99 mg/dL when fasting, below 140 mg/dL two hours after eating, and below 6% for an A1c test. Nurses play an important role in properly conducting blood glucose tests and documenting the results.

6. Introduction:
Glucose comes from carbohydrate foods. It is the
main source of energy used by the body. Insulin
is a hormone that helps your body's cells uses
the glucose. Insulin is produced in the pancreas
and released into the blood when the amount of
glucose in the blood rises.

7. 
Normally, your blood glucose levels increase
slightly after you eat. This increase causes
your pancreas to release insulin so that your
blood glucose levels do not get too high. Blood
glucose levels that remain high over time can
damage your eyes, kidneys, nerves, and blood
vessels.

9. Definition
A blood glucose test measures the
amount of a sugar called glucose
in a sample of patient blood.

10. Purposes
 Check for prediabetes and diabetes.
 Monitor treatment of diabetes.
 Check for diabetes that occurs during pregnancy
(gestational diabetes).
 Screen for high blood glucose level
(hyperglycemia) or low blood glucose level
(hypoglycemia).

11. Prediabetes is a wake-up call that you’re on the
path to diabetes.
If you have it, your blood sugar (glucose) level
is higher than it should be, but not in the
diabetes

12.  3 Key Lifestyle Changes to Make Now
 Lifestyle changes can help many people with prediabetes delay
or prevent it from becoming diabetes.
 In a large research study called the Diabetes Prevention
Program,
 1. Weight control. If you're overweight, your prediabetes is
more likely to turn into diabetes. Losing even as little as 5% to
10% of your body weight makes a difference.
 2. Exercise. Get moderate exercise for 30 minutes a day, such
as cycling, swimming, or brisk walking
 3. Nutrition. Go for meals that, vegetables, and whole grains.
Limit calories, serving sizes, sugar, and starchy. Favor fiber-
rich foods, which help you feel full and not eat too much

14. gestational diabetes
The placenta supports the baby as it grows.
Hormones from the placenta HPL help the
baby develop. But these hormones also block
the action of the mother's insulin in her body.
This problem is called insulin resistance.
Insulin resistance makes it hard for the
mother's body to use insulin.

15. Types
Fasting blood sugar (FBS) measures blood
glucose after you have not eaten for at least
8 hours. It is often the first test done to
check for prediabetes and diabetes.

16. Normal 70-99
Prediabetes if your blood sugar is 100-
125
Diabetes if your blood sugar is 126 or
higher

17. 2-hour postprandial blood sugar
measures blood glucose exactly 2 hours after you start eating a meal.
Diabetes may be diagnosed if the 2-hour post-
prandial blood sugar level is higher than
normal for a person's age. This is true
especially if the test on two different days
gives the same results and the person has
symptoms of diabetes. Less than 140mg

19. Random blood sugar (RBS)
measures blood glucose regardless of when
you last eat. Several random measurements
may be taken throughout the day.
Random testing is useful because glucose
levels in healthy people do not vary widely
throughout the day. Blood glucose levels that
vary widely may mean a problem. This test is
also called a LESS 200 casual blood glucose
test.

20. Oral glucose tolerance test is used to
diagnose prediabetes and diabetes. blood
glucose measurements taken after you drink a
sweet liquid that contains glucose.
 This test is commonly used to diagnose
diabetes that occurs during pregnancy
(gestational diabetes).
This test is not commonly used to diagnose
diabetes in a person who is not pregnant.

23. Glycohemoglobin A1c
measures how much sugar (glucose) is stuck to
red blood cells. used to diagnose diabetes. It
also shows how well your diabetes has been
controlled in the last 2 to 3 months and
whether your diabetes medicine needs to be
changed.
