h. Interpretation of Quality Control Results
a. Results are displayed on the screen as a number. Any result that shows an "out of range"
message or "Fail" is an indication that the system may not be performing correctly for
patient testing.
b. Patient testing may not be performed if quality control testing results are not within
acceptable limits and the meter will not display the patient testing option if scheduled
quality control results exceed acceptable limits.

9. Special considerations for Patient Testing

a. Hematocrit should be between 10–65 %.
b. Lipemic samples (triglycerides) in excess of 1800 mg/dL may produce elevated results.
c. Blood concentrations of galactose >15 mg/dL will cause overestimation of blood glucose
results.
d. Intravenous administration of ascorbic acid which results in blood concentrations of
ascorbic acid >3 mg/dL will cause overestimation of blood glucose results.
e. If peripheral circulation is impaired, collection of capillary blood from the approved
sample sites is not advised as the results might not be a true reflection of the
physiological blood glucose level. This may apply in the following circumstances: severe
dehydration as a result of diabetic ketoacidosis or due to hyperglycemic hyperosmolar
non-ketotic syndrome, hypotension, shock, decompensated heart failure NYHA Class IV,
or peripheral arterial occlusive disease.
f. Hematocrit—the acceptable range for the ACCU-CHEK INFORM ll test strips is 20-65%
for values below 200 mg/dL and 20-55% for values above 200 mg/dL.
g. Patients in Isolation
1. The meter can be placed in a plastic bag.
2. A small hole can be punctured in the bag.
3. The strip can be placed in the meter through the hole and the meter programmed as
usual.
4. After the testing is done the plastic bag is discarded and the meter will be wiped
down.

10. Procedure for Patient Testing

a. Wash hands and don personal protective equipment (gloves, gowns, etc.) as required by
infection control and isolation policies and procedures.
b. Assemble the finger-stick equipment, the meter, and the test strips at the patient bedside.
c. Identify the patient by armband and explain the procedure.
d. Wash and dry patient's hands/heel with soap and water before obtaining a blood sample.
Alcohol wipes are not recommended for use.
e. Turn on the meter.
f. Scan your operator barcode or enter your 5 digit Lawson ID. You must enter a leading zero if
you have a 4 digit Lawson number. If your ID is not on record in the laboratory you will be
locked out of the instrument. NOTE: If the operator ID you enter is not accepted, attempt to
re-enter it. If it is still rejected, contact your supervisor or Point of Care Coordinator. DO NOT
attempt to perform tests under another operator's ID.
g. From the Main Menu, touch Patient Test.
h. Scan the patient's financial number from the bar-coded wristband for the patient ID.
i. In any situation where a patient has not been registered, the number 0911911 should
be used as the patient identification number.
ii. A custom comment should be entered in the ACCU-Check Inform ll system with the
patient's name at the time of testing. This will allow for charting and billing when a
financial number is assigned in the future.
iii. In certain situations, an employee may need to have a glucose test done. If this
occurs, the number 0123456 should be used. This will not be documented as a
patient test.
i. Confirm that the meter is coded (calibrated) to the same test strip code that is printed on the
test strip vial by scanning the test strip vial. Contact the laboratory if you are unable to
confirm the correct test strip code.
j. You will now see a picture of a test strip with a downward flashing arrow on the screen
indicating that you are ready to insert a test strip into the meter.
k. Remove a test strip from the vial and immediately recap the vial. Insert the test strip into the
meter in the direction of the arrows and with the "ACCU-CHEK" lettering facing upward. The
