Blood Glucose Monitoring, Pediatric
Monitoring your child's blood sugar (glucose) is an important part of managing your child's diabetes. Blood glucose monitoring involves checking blood glucose as often as directed and keeping a log or record of the results over time.
Checking your child's blood glucose regularly and keeping a blood glucose log can:
Help you and your child's health care provider adjust your child's diabetes management plan as needed, including medicines or insulin.
Help you and your child understand how food, exercise, illnesses, and medicines affect blood glucose.
Let you and your child know what your child's blood glucose is at any time. You can quickly find out if your child has low blood glucose (hypoglycemia) or high blood glucose (hyperglycemia).
Your child's health care provider will set individualized treatment goals for your child's blood glucose levels before meals (preprandial) and after meals (postprandial).
Supplies needed:
-
Blood glucose meter.
-
Test strips for your child's meter. Each meter has its own strips. You must use the strips that come with your child's meter.
-
A needle to prick the finger (lancet). Do not use a lancet more than one time.
-
A device that holds the lancet (lancing device).
-
A journal or log book to write down your child's results.
How to check your child's blood glucose
Checking your child's blood glucose
-
Wash your hands and your child's hands for at least 20 seconds with soap and water.
-
Prick the side of your child's finger (not the tip) with the lancet. Use a different finger each time you check blood glucose.
-
Gently rub the finger until a small drop of blood appears.
-
Follow instructions that came with the meter for inserting the test strip, applying blood to the strip, and using the blood glucose meter.
-
Write down the result and any notes in the journal.
Using alternative sites
Some meters allow you to use areas of your child's body other than the finger (alternative sites) to test the blood. The most common alternative sites are the forearm, the thigh, and the palm of the hand.
Alternative sites may not be as accurate as the fingers because blood flow is slower in those areas. This means that the result you get may be delayed, and it may be different from the result that you would get from your child's finger.
Use the finger only, and
do not use alternative sites, if:
