Taking control of your
diabetes can help you feel
better and stay healthy.
Research shows that keeping
your blood glucose (blood sugar) close to normal
reduces your chances of having eye, kidney, and nerve
problems. To control your diabetes, you need to know
your blood glucose numbers and your target goals.
There are two different tests to measure
your blood glucose.
The A1C test (pronounced A-one-C)
reflects your average blood glucose level
over the last 3 months. It is the best
way to know your overall blood glucose
control during this period of time. This
test used to be called hemoglobin A-1-C
or H-b-A-1-C.
The blood glucose test you do
yourself uses a drop of blood and
a meter that measures the level of
glucose in your blood at the time
you do the test. This is called selfmonitoring
of blood glucose (SMBG).
If you
have diabetes…
know your
blood sugar numbers!
You and your health care team need to use both
the A1C and SMBG tests to get a complete
picture of your blood glucose control.
Why should I check my blood glucose?
Self monitoring of blood glucose, or SMBG, with a meter
helps you see how food, physical activity, and medicine
affect your blood glucose levels. The readings you get can
help you manage your diabetes day by day or even hour
by hour. Keep a record of your test results and review it
at each visit with your health care team.
How do I test my own blood glucose?
To do SMBG, you use a tiny drop of blood and a meter to
measure your blood glucose level. Be sure you know how
to do the test the correct way. Also, ask your health care
team whether your meter gives the results as plasma or
whole blood glucose. Most new meters provide the results
as plasma glucose.
What is a good
self-testing blood
glucose goal?
Set your goals with your
health care team. Blood
glucose goals for most people
with diabetes when selftesting
are on these charts.
How often should I check my blood glucose?
Self-tests are usually done before meals, after meals, and/or
at bedtime. People who take insulin usually need to test
more often than those who do not take insulin. Ask your
health care team when and how often you need to check
your blood glucose. If I test my own blood glucose, do I still need the
A1C test? Yes. The results of both SMBG and A1C tests help you
and your health care team to manage your diabetes and
get a complete picture of your diabetes control.
Does my insurance pay for the A1C test, self-testing
supplies, and education?
Most states have passed laws that require insurance
coverage of SMBG supplies and diabetes education.
Check your coverage with your insurance plan.Medicare
covers most of the cost of diabetes test strips, lancets
(needles used to get a drop of blood), and blood glucose
meters for people who have diabetes. Ask your health care
team for details about Medicare's coverage of the A1C.
What is the A1C test?
The A1C test is a simple lab test that reflects your average
blood glucose level over the last 3 months. A small blood
sample to check your A1C can be taken at any time of
the day.
Why should I have an A1C test?
The A1C test is the best test for you and your health care
team to know how well your treatment plan is working
over time. The test shows if your blood glucose levels
have been close to normal or too high. The higher the
amount of glucose in your blood, the higher your A1C
result will be. A high A1C result will increase your
chances for serious health problems.
What is a good A1C goal?
You and your health care team should discuss the A1C
goal that is right for you. For most people with diabetes,
the A1C goal is less than 7. An A1C higher than 7 means
that you have a greater chance of eye disease, kidney
disease, or nerve damage. Lowering your A1C—by any
amount— can improve your chances of staying healthy
.
.
If your number is 7 or
more, or above your goal,
ask your health care team
about changing your
treatment plan to bring
your A1C number down.
If I am pregnant, what is my A1C goal?
Keeping your A1C less than 6 if you are pregnant will
help ensure a healthy baby. If possible, women should
plan ahead and work to get their A1C below 6 before
getting pregnant.
How often do I need an A1C test?
Ask for an A1C test at least twice a year. Get the test more
often if your blood glucose stays too high or if your
treatment plan changes.
What about home testing for A1C?
You and your health care team should decide if home
testing is a good idea for you. If so, be sure to do the test
the correct way and discuss the results with your doctor.
The A1C Test
The Best Measure of
Long-Term Diabetes Control
Level of A1C
Control Number
Normal 6 or less
Goal less than 7
Take action 7 or more
1. Talk to your health care team about your
A1C goals and your SMBG goals.
2. Ask for an A1C test at least twice a year.
3. Ask your health care team what your A1C
number is, what it means, what it should
be, and what you need to do to reach
your A1C goal.
4. Check your own blood glucose as often
as needed and go over the results at each
visit with your doctor and health care
team.
5. To keep your blood glucose under
control, eat the right foods in the right
amounts. Get regular physical activity
as advised by your health care team.
Take medicines that have been prescribed
for you.
6. Ask your health care team about your
blood pressure and cholesterol numbers
and what your goals should be.
