User Guide

Before You Get Started

Read this additional information before testing your blood glucose with the Accu-Chek SugarView app and the Accu-Chek Active test strips. The User’s Manual of the Accu-Chek SugarView app contains all the information you need to perform a test and understand your test results. If you have questions, contact customer support. Contact information for your country can be found in the main menu. Open the app, and go to PROFILE > Support Information > Support Contact.

WARNING
The package insert contains warnings:
A WARNING indicates a foreseeable serious hazard.
Self-testing is not a substitute for visits to your doctor. You must receive proper instruction from a qualified healthcare professional before you start self-testing your blood glucose. Your healthcare professional will determine the appropriate blood glucose target range jointly with you.
The cap of the test strip container contains a non-toxic silicate-based drying agent. If you accidentally swallow any of this, drink plenty of water!
These test strips deliver results that correspond to blood glucose concentrations in plasma as per the recommendation of the International Federation of Clinical Chemistry and Laboratory Medicine (IFCC) [1]. Therefore, the Accu-Chek SugarView app displays blood glucose values that refer to plasma although you always apply whole blood to the test strip.
The normal fasting glucose level for a non-diabetic adult is below 100 mg/dL (5.6 mmol/L). A criterion for the diagnosis of diabetes in adults is a fasting glucose level of 126 mg/dL or higher (7.0 mmol/L or higher) confirmed in two tests [2, 3, 4]. Adults with a fasting glucose level between 100 and 125 mg/dL (5.6 and 6.9 mmol/L) are defined as having impaired fasting glucose (prediabetes) [2]. Other diagnostic criteria for diabetes exist.
Consult your doctor or diabetes nurse to determine if you have diabetes or not.

The User’s Manual of the Accu-Chek SugarView app includes details on where to get information on the effects and prevalence of diabetes.

WARNING
Risk of suffocation
This product contains small parts that can be swallowed.
Keep the small parts away from small children and people who might swallow small parts.

Blood Volume and Test Time

The test strip requires 1–2 μL of blood (1 µL (microliter) = 1 thousandth of a milliliter) per blood glucose test. The blood glucose test takes approximately 13–45 seconds.

Storing and Using Test Strips Properly

WARNING
Risk of a serious health incident
If the test strips are not stored or used properly, they can deliver incorrect test results. This can lead to serious health incidents.

• Store the test strips at temperatures between +2 and +30 °C in a dry place away from direct sunlight.
  Also, note the following instructions:

• The drying agent contained in the cap of the test strip container protects the test strips from moisture. Always store the test strips in their original test strip container with the cap closed.

• Close the test strip container tightly with its original cap after removing a test strip. Do not remove test strips from the test strip container with moist hands. This enables the drying agent to retain its effect.

• If you store the test strip container in a refrigerator, leave the closed container to stand at an ambient temperature. Only remove a test strip once the test strip container has warmed up to ambient temperature. This prevents condensation from forming in the test strip container.

• Do not store any other objects such as cleaning cloths or used test strips in a test strip container that contains unused test strips. This could make the test strips unusable.

• When you perform a blood glucose test with the app, the temperature must be between +15 and +40 °C.

• Do not test in direct sunlight.

• Use only test strips which are within the use-by date. The use-by date is printed next to the e symbol on the packaging and on the label of the test strip container. The use-by date applies for test strips from a new, unopened test strip container and for test strips from a test strip container that has already been opened.

• Use a test strip only once. Test strips are for single use only.

Test Principle

On each test strip, there is a test area containing reagents. When blood is applied to the test area, the glucose dehydrogenase enzyme (Mut. Q-GDH 2) reacts with the blood glucose. The subsequent chemical reaction changes the color of the test area.
The app performs a digital visual test of the color of the control window and interprets the color change on the test strip using the standard color information provided by the accessory color card.
The app indicates on the display of the smartphone if your test result falls above, below, or within your target range. Displayed will be a semi- quantitative blood glucose range.

Blood Glucose Ranges

greater than
600| greater than
33.3| outside the measuring range, blood glucose cannot be properly detected
301 to 600| 16.7 to 33.3| very high, exercise and doctor visits recommended
181 to 300| 10.0 to 16.6| high, exercise recommended
131 to 180| 7.3 to 10.0| after a meal (within 2 hours): within the target range, good blood glucose result before meal or fasting: slightly high blood glucose result, exercise recommended
71 to 130| 3.9 to 7.2| within the target range, good blood glucose result
20 to 70| 1.1 to 3.9| low or very low, eating or drinking something sugary, and an immediate doctor visit recommended
lower than 20| lower than 1.1| out of measuring range, blood glucose cannot be properly detected

Checking the Test Result

Check by Color Comparison
The test strip itself allows you to estimate the test result through color comparison and thus check the displayed test result in addition. The color comparison serves only as a plausibility check of the test result.

• Before the test: On the back of the test strip, there is a round, colored control window. Compare the color of this window with the colored dots on the label of the test strip container. The color of the control window must match the color of the top dot (0 mg/dL, 0 mmol/L). If the control window is a different color, do not perform a test with that test strip.
• After the test: The label on the test strip container shows blood glucose values in mg/dL and mmol/L next to each colored dot.
  Within 30 to 60 seconds after applying the blood to the test strip, compare the color of the control window on the back of the test strip with the dot that comes closest to your test result. If the color deviates significantly, repeat the test. If the color still deviates in further tests, contact customer support.

Check Performed by the App
The app automatically tests your mobile device’s camera and system every time you scan a test strip and lets you know if something is wrong. Additionally, the app checks the quality of the test strip and rejects an unsuitable test strip. In this way, the app ensures that the blood glucose result is measured correctly.

Performance Characteristics

For performance characteristics of the app in combination with the test, strips refer to the Accu-Chek SugarView app User’s Manual. Go to PROFILE > Support Information > App Manual.

Limitations

Certain health conditions can lead to incorrect test results. If you know that one or more of the following health conditions apply to you, do not use the test strip. If you are unsure whether any of the health conditions apply to you, contact your healthcare professional.

• Intravenous administration of ascorbic acid may lead to falsely elevated test results. Concentrations of ascorbic acid in the blood greater than 8 mg/dL (greater than 0.45 mmol/L) lead to falsely elevated blood glucose test results.

• Parenteral administration of galactose and galactosemia can lead to falsely elevated test results. Concentrations of galactose in the blood greater than 15 mg/dL (greater than 0.83 mmol/L) lead to falsely elevated test results. Test results for neonates exhibiting symptoms of galactosemia must be confirmed by laboratory tests.

• Concentrations of bilirubin in the blood up to 40 mg/dL (680 µmol/L) do not interfere. Higher concentrations have not been tested.

• Do not use it when undergoing ceftriaxone treatment.
  Concentrations of ceftriaxone in the blood greater than 100 μg/mL (greater than 180 µmol/L) lead to falsely lowered blood glucose test results.

• If peripheral circulation is impaired, capillary blood 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.

• You may use blood with a hematocrit of 20 to 55 %.

• Visually impaired people must not use the Accu-Chek SugarView app, the test strips, and the control solutions.

• For any limitations on using blood samples from other sites on your body besides the fingertip (AST testing), refer to the package insert inside the test strip box.

• If you are on insulin therapy or if you take hypo-inducing oral antidiabetics (for example, sulfonylureas), this may lead to incorrect test results. In such a case do not use the app for testing your blood glucose. Do not use the test results of the app as a basis for making therapy decisions.
