This document provides instructions for point of care blood glucose testing using a glucometer. It defines hypoglycemia and hyperglycemia as low and high blood sugar, respectively. It outlines the objectives, materials needed, testing procedure, and documentation for blood glucose testing. The key steps are selecting an appropriate site on the finger or other area, using a lancet to obtain a blood sample, applying the sample to a test strip and placing it in the glucometer, and interpreting the results on the display. Abnormal results require immediate attention and may indicate issues with calibration. Results should be recorded along with interventions in the patient's diabetic chart or other documentation.

2. Objectives:
 Define indications for blood glucose monitoring
 Recognize the HYPO and HYPER-glycemia
 Distinguish between normal and abnormal blood glucose
level
 Demonstrate the steps in the use of Glucometer
 Measure and document accurate blood glucose.

3. INTRODUCTION
Point of Care Testing

4. What is it used for?
• use to find out if your blood sugar
levels are in the healthy range.
• use to help diagnose and monitor
diabetes.
Why do I need a blood glucose
test?
To test if you have
symptoms of high glucose
levels (hyperglycemia) or
low glucose levels
(hypoglycemia).
A blood glucose test measures
the glucose levels in your blood.

5. Hypoglycemia
is low blood sugar
Hyperglycemia
is high blood sugar

6. Blood Glucose Meter
• is a small, portable machine that's
used to measure how much glucose (a
type of sugar) is in the blood (also
known as the blood glucose level).

7.  Glucometer
 Lancet
 Strips
 Alcohol swab
 Gauze/Cotton balls
 Gloves

8. Sites for skin puncture:
finger tips, ear lobes, and
heels (infants)
Avoid sites that are
swollen, bruised, cyanotic,
scarred, or calloused (poor
blood flow)
Preffered fingers - middle
and ring finger
Use the side of finger

9. Blood Glucose Test
Reagent strip - Check strips for expired dates; place large drop of blood on strip and time
according to instructions
Glucose meter:
 Be sure meter is calibrated properly (coding)
 Perform control testing according to policy
 Place drop of blood on reagent strip
Apply pressure to site until bleeding stops
Discard lancet in sharps container

10. *The following messages may mean there is a blood glucose result that
requires immediate attention or there may be a problem with the test
strip:
• LO = the blood glucose may be lower than 20 mg/dL (1.1 mmol/L).
• HI = the blood glucose may be higher than 500 mg/dL (27.8 mmol/L).
• Test. Error E-3 = there may be a test error.
• Test Error E-4 = the blood glucose may be too high to be read by the
system.
• If any of these messages show, check that the meter is calibrated
correctly and repeat the test with a new test strip.
