FORA COMFORT check G40 Blood Glucose Test Strip User Manual

FORA COMFORT check G40 Blood Glucose Test Strip

Warnings

• For in vitro diagnostic use (for use outside of the body only).
• For single use only.
• Healthcare professionals and other users testing multiple patients with this system should handle everything that has come into contact with human blood carefully to prevent transmitting infectious diseases, including sanitized objects.
• Please read this sheet and your Blood Glucose Monitoring System Owner’s Manual before you use this test strip. Use only FORA Test Strips with FORA Blood Glucose Monitoring System to obtain accurate results, and be covered by the manufacturer’s warranty.
• Results may be inaccurate when testing on patients with abnormally low blood pressure or those who are in shock.
• Please do not use FORA Blood Glucose Monitoring System on critically ill patients. While the blood glucose result is extremely hyperglycemia (over 600  mg/dL (33.3 mmol/L)), the collection of capillary blood from the approved sample sites is not advised when the peripheral circulation is impaired as the delivery of physiological blood glucose level might not be a true reflection. The following circumstances may apply: severe dehydration as a result of diabetic ketoacidosis or due to stress hyperglycemic, hyperosmolar non-ketotic coma, shock, decompensated heart failure NYHA Class IV or peripheral arterial occlusive disease.
• Keep test strips and lancets away from small children. If swallowed, consult a doctor immediately for advice.

Intended Use

FORA test strips, when used together with FORA Blood Glucose Monitoring System, allow your blood glucose levels to be measured by yourself at home or by healthcare professionals. It uses fresh whole blood samples from the finger, and the following areas: the palm, forearm and upper arm. This system is not intended for use in the diagnosis or screening of diabetes mellitus.
Professionals may test with capillary and venous blood sample; home use is limited to capillary whole blood testing. Use only heparin for anticoagulation of whole blood.
Please do NOT use EDTA for anticoagulation.

Limitations

• Hematocrit: The hematocrit level is limited to between 35% and 60%. Please ask your healthcare professional if you do not know your hematocrit level.
• Neonatal Use: This test strip must not be used for the testing of newborns.
• Please see Appendix: Summary of substances and concentrations in excess of limitation with interference.
• Altitude Effects: Altitudes up to 3,275 m (10,742 ft) do not affect test results.
• Do not test blood glucose during or soon after a xylose absorption test. Xylose in the blood can produce elevated glucose results

Storage and Handling

IMPORTANT: Do not use the test strips if they have expired.

► Test strips expire 6 months after first opening. Write the first opening date on the test strip vial when you first opened it.
► Store the test strips in a cool, dry place between 2°C and 30°C (35.6°F and 86°F) and below 85% relative humidity.
► Keep the test strips away from direct sunlight. Do not store the test strips in high humidity.
► Store the test strips in their original vial ONLY. Do not transfer them to a new vial or any other containers.
► Do not touch the test strips with wet hands.
► Use each test strip immediately after taking it out of the vial. Close the vial immediately after taking out a strip.
► Keep the vial closed at all times.
► Do not bend, cut, or alter the test strip.

Testing Your Blood Glucose

PLEASE WASH AND DRY YOUR HANDS BEFORE PERFORMING ANY TESTS.

Please refer to your Owner’s Manual for more information.

The used lancet and test strip are potentially biohazardous. Please dispose of them carefully according to your local regulations.

Reading Your Result

Your blood glucose readings deliver plasma equivalent results and are displayed in mg/dL or mmol/L.

Reference values

Source: American Diabetes Association (2012). Clinical Practice Recommendations. Diabetes Care, 35 (Supplement 1): S1-100.

Please consult your doctor to determine a target range that works best for you.

Questionable or inconsistent results

If your test results are unusual or inconsistent with how you are feeling:

• Make sure the confirmation window of the test strip is completely filled with blood.
• Check the expiry date of the test strips.
• Check the performance of your meter and test strip with the control solutions.

Please Note: Unusually high or low blood glucose levels may be symptoms of a serious medical condition. If most of your results are unusually high or low, please contact your healthcare professional.

Quality Control Testing

Our control solutions contain a known amount of glucose that can react with test strips.
You can check the performance of the meter, test strip and your technique by comparing the control solution results with the range printed on the label of test strip vial. Checking regularly can ensure your test results are accurate. Please refer to the Owner’s Manual for complete testing instructions.

IMPORTANT: The reference range of the control solutions may vary with each new test strip. Make sure you check the range on the label of vial or individual foil pack of your current test strip.

Chemical Components

Additional Information for Healthcare Professionals

Always wear gloves and follow your facility’s biohazard control policy and procedures when performing tests involving patient blood samples. Use fresh whole blood samples only. Professionals may use test strips to test capillary and venous whole blood.
Sample Size: 0.7 μL
Reaction Time: 7 seconds
System Measurement Range: 20 mg/dL to 600 mg/dL
Hematocrit Range: 35% to 60%

Accuracy

The table below displays how often FORA G40 achieves this target. The chart is based on a study carried out on 160 patients (each patient was tested six times which had 960 test results) to see how well FORA G40 performed compared to YSI-2300 reference method results.

Table 1 Accuracy results for glucose concentration < 100 mg/dL (5.55 mmol/L)

Within ±5 mg/dL (Within ±0.28 mmol/L)| Within ±10 mg/dL (Within ±0.55 mmol/L)| Within ±15 mg/dL* (Within ± 0.83 mmol/L)
---|---|---
60.6% (181/294)| 90.1% (265/294)| 100% (294/294)

Table 2 Accuracy results for glucose concentration≧100 mg/dL (5.55 mmol/L)

Table 3 Accuracy results for glucose concentrations between 32.4mg/dL (1.80mmol/L ) to 532.0mg/dL (29.56mmol/L)

Within ±15 mg/dL or ±15% (Within ±0.83 mmol/L or ±15%)

97.5% (936/960)

Note: *Acceptance criteria in EN ISO 15197: 2015 95% of all differences in glucose values (i.e., YSI-2300 reference values minus glucose values of FORA G40) should be within ±15 mg/dL (0.83 mmol/L) for glucose concentration < 100 mg/dL (5.55 mmol/L), and within ±15% for glucose concentration ≥ 100 mg/dL (5.55 mmol/L).
When Test Strips results are compared to the reference values, difference values below 100 mg/dL (5.55 mmol/L) are expressed in mg/dL or mmol/L, while those above 100 mg/dL (5.55 mmol/L) are in percent.

User performance

160 subjects tested on the fingertip and the alternative sites, the palm, the forearm and the upper arm. The tables show how well FORA G40 performed compared to YSI-2300 reference method results.
