Test Strips

The user will receive an E-4 error code.

Yes, as with any test strip, heat, humidity and other environmental conditions can affect strips.

No, there is no ability to squeeze extra blood from the finger to dose a strip a second time.

The Accu-Chek Instant system was designed to assist users to easily conduct a test. Several features were designed for this purpose:

  • Easy-edge test strip has a wide application area compared to leading brands
  • Strips are placed electrode end down in the vial, so that they can be inserted easily into the meter with minimal handling
  • The used strip can easily and hygienically be removed from the meter with the strip ejector

The Accu-Chek Instant test strip requires only a small speck of blood (0.6 μL).

The Accu-Chek Instant test strip utilises the FAD-GDH chemistry.

No, the meter will not lock a user out if they have used expired test strips.

Yes, a clear protective barrier runs along the entire length of the test strip to protect the strip and chemistry. Blood applied anywhere along the yellow edge of the strip can be quickly pulled into the test strip.

No, there is no compatibility between the Accu-Chek Instant meter and these other Accu-Chek test strips.

The strip ejector allows a user to dispose of a used test strip hygienically.

Yes, it is possible to test with all types of blood including capillary, venous, arterial, and neonatal. Please refer to the user manual and speak to your healthcare professional for more information.

The Accu-Chek Aviva test strips can be used with the following Accu-Chek meters:

• Accu-Chek Aviva 
• Accu-Chek Aviva Combo 
• Accu-Chek Aviva Expert 
• Accu-Chek Aviva Insight

The system in your meter automatically detects when enough blood has been applied to the strip and begins the test, even if some yellow is still visible. 

The only time you need to apply more blood is when the blood drop symbol continues to flash in the display.

Using test strips that have expired can cause your results to be inaccurate. If your test strips have expired, throw them away and begin using a new vial of strips. The expiration date is printed on every vial of test strips.

The Accu-Chek Mobile test cassettes can be used with the Accu-Chek Mobile meter.

Using test cassettes that have expired can cause your results to be inaccurate. If your test cassettes have expired, throw them away and begin using a new test cassette. The expiration date is printed on every test cassette.

Explore the different ways you can simply handle Accu-Chek Guide test strips when removing them from the SmartPack test strip vial:

  1. Front slide
  2. Side pinch
  3. Pinch and pull
  4. Back slide

Remember to follow all instructions in the package insert (wash and dry hands, do not bend or get dirt on the test strip, and close the cap tightly when finished).

If the test cassette you removed still has unused tests and is still within the "use by" date, you can reinsert the cassette into the meter. The meter recognises the cassette, the number of available tests and the expiry date.

If a standard test cassette is inserted in to the meter, the meter checks regularly when the cassette was inserted and calculates the use-by period from this. Each test cassette must be used up within 90 days (use-by period). If a standard test cassette is inserted into the meter, the use-by period is calculated from the date when the cassette was first placed in the meter. This date is stored in the cassette. 

The meter also checks whether the expiry date of the cassette has been reached. The expiry date is shown on the test cassette box. 

If either of the two dates – use-by period or expiry date – is exceeded, the cassette has expired and further tests cannot be performed with this test cassette. 

If a test is started and the cassette is going to expire shortly or has already expired, the meter will inform you of this. 

A notification relating to the expiry of the test cassette appears 10 days before it expires, subsequent notifications appear 5, 2 and 1 day(s) before expiry. 

If the test cassette has expired, a message will ask the user to replace it.

No, it is not possible to insert the cassette the wrong way.

When a new test cassette is inserted, the Radio Frequency Identification (RFID) tag informs the meter about the specific properties of the chemistry in this test cassette and all coding information is given. The meter turns on, the display check appears and the user is shown the information about the cassette's expiry date. The number of available tests is indicated then the main menu is displayed. The meter is now ready for testing.

Please refer to the user manual and how-to videos for more information about how to change the test cassette in the Accu-Chek Mobile system.

The target expiration date is 18 months from the date of manufacture.

No. Accu-Chek Aviva meters are designed exclusively for use with Accu-Chek Aviva test strips.

No, as this could cause measurements to be incorrect. Please ensure that you carry enough valid test strips.


Before the user doses the test strip, the Accu-Chek Aviva meter runs quality checks of the strip chemistry to make sure the strip will give a valid test result. This ensures that the strip has not been exposed to outside environmental factors, such as humidity.
