2-HOUR POSTPRANDIAL GLUCOSE
GENERAL
INFORMATION:
What
is it? A 2-hour postprandial (post-pran-d-ul) glucose is a
blood test. Postprandial means "after a meal." Glucose,
a type of sugar, is the main source of energy in your body.
Your health caregiver may ask you to drink a special glucose
solution instead of eating a meal. A blood sample to be tested
for glucose is taken 2-hours after the meal or drink is finished.
Why
do I need it? You may need this test to learn if you have
diabetes (dia-b-tees).
How
do I get ready for the test?
Sometimes
a fasting blood sugar (FBS) will be done before the 2 hr PPG.
Ask your health caregiver for the CareNote about FBS.
You should rest during the 2 hours between the meal or drink
and the blood collection. Tell your health caregiver if you
cannot finish the meal or drink or if you vomit. Do not smoke,
eat, drink, or exercise during the 2 hours. These activities
cause the blood sugar levels to be falsely low or falsely
high.
How is the blood collection done? A health caregiver will
put a wide rubber strap around your arm and tighten it. Your
skin will be cleaned with alcohol. A small needle attached
to a special test tube will be put into a vein in your arm
or hand. The tube has suction to pull the blood into it. When
the tube is full, the rubber strap, needle and tube are removed.
The caregiver will press a piece of cotton where the needle
was removed. You may be asked to hold the cotton on the site
for a few minutes to help stop the bleeding. Tape may then
be put over the cotton on your arm.
After
the test. You may remove the tape and cotton in about 20 to
30 minutes. Call your health caregiver to get the results
your test. Your health caregiver will explain what your test
results mean for you. Follow the instructions of your health
caregiver.
