Accu-Chek Instant Test Strips Expiry & Storage Guide: How to Store Them Correctly
Microsidd India
Accu-Chek Instant Test Strips are used with both the Accu-Chek Instant and Accu-Chek Instant S blood glucose meters. Correct storage, careful handling and checking the printed expiry date are important parts of using the strips as intended.
Each test-strip vial has a manufacturer use-by or expiry date. Do not use Accu-Chek Instant strips after that printed date.
This Microsidd Knowledge Hub guide explains where to check the expiry, how to store the strip vial, what to do if the container is left open, how heat and moisture can affect storage conditions, when a control test may be useful and what to consider when buying 50 or 100 strips.
Quick answer:
Keep Accu-Chek Instant Test Strips in their original container,
close the vial promptly after removing a strip, follow the storage conditions
printed on the manufacturer packaging and
never use strips after the printed use-by date.

Where Is the Expiry Date on Accu-Chek Instant Test Strips?
Check the original Accu-Chek Instant test-strip vial and manufacturer packaging for the printed use-by or expiry date.
The date printed on the physical product supplied with your order should be treated as the final reference for that particular strip batch.
Microsidd may also display the current available stock expiry on the relevant product page where that information has been updated.
Because new batches arrive over time, an expiry date visible in an older screenshot, advertisement, review or search result may not represent the batch currently in stock.
Can Expired Accu-Chek Instant Test Strips Be Used?
No. Accu-Chek advises users not to use test strips past the use-by date printed on the test-strip container.
If the printed date has passed, discard the expired strips and begin using an in-date vial of compatible Accu-Chek Instant Test Strips.
Do not continue using an expired strip simply because:
- the vial is still sealed,
- some strips remain unused,
- the strip looks normal, or
- the meter still accepts the strip.
Why Does Test Strip Expiry Matter?
Blood glucose test strips contain chemical components designed to work within specified manufacturer conditions.
The printed expiry date forms part of those product-use conditions. Using strips beyond their use-by date is not recommended because the manufacturer no longer intends them to be used for testing after that point.
When accurate blood glucose information matters, the safer approach is simple: use compatible, correctly stored, in-date strips.
Do Accu-Chek Instant and Instant S Use the Same Strips?
Yes. Both meters use Accu-Chek Instant Test Strips.
The expiry and storage guidance therefore applies whether you use:
- Accu-Chek Instant, or
- Accu-Chek Instant S.
The compatibility rule is:
Accu-Chek Instant → Accu-Chek Instant Test Strips
Accu-Chek Instant S → Accu-Chek Instant Test Strips

How Should Accu-Chek Instant Test Strips Be Stored?
Always follow the storage instructions printed on the specific Accu-Chek Instant strip vial, carton and product insert supplied with your batch.
Good strip-handling practices include:
- Keep unused strips in their original test-strip vial.
- Remove only the strip required for the current test.
- Close the container promptly and securely after removing a strip.
- Keep the strips clean and dry.
- Protect the strips from inappropriate heat and humidity.
- Do not transfer loose strips to an unrelated container.
- Do not use visibly damaged or contaminated strips.
- Check the printed use-by date before testing.
Why Should the Test Strip Vial Be Closed Promptly?
The original strip vial is part of the manufacturer's intended storage system.
Leaving the container open unnecessarily can expose the remaining strips to environmental conditions such as humidity or contamination.
A simple routine is:
Open vial → Remove one strip → Close vial → Perform the test
There is no need to leave the vial open while preparing the lancing device, washing your hands or obtaining the blood sample.
What If the Accu-Chek Instant Strip Vial Was Left Open?
Accu-Chek specifically lists a test-strip container being left open as one of the situations where a control test may be useful.
If the vial was accidentally left open:
- Close the container securely.
- Consider whether the strips may have been exposed to moisture, heat or contamination.
- Inspect the strip and container for obvious damage.
- Follow the manufacturer instructions supplied with your strips.
- Consider performing a control test according to Accu-Chek guidance.
If you are uncertain about the condition of the strips, do not rely on guesswork. Follow the manufacturer support instructions for that product.
What Is a Control Test?
A control test is used to check whether the meter and test strips are working together as expected using the appropriate control solution rather than a blood sample.
Accu-Chek recommends considering a control test in situations including:
- opening a new test-strip box,
- leaving the strip container open,
- suspecting that the strips are damaged,
- wanting to check the meter and strips,
- exposure to extreme temperature or humidity,
- dropping the meter,
- receiving a result that does not match how you feel, or
- checking whether the testing procedure is being performed correctly.
Follow the Accu-Chek instructions for the correct control solution and testing procedure.
Can Heat Affect Accu-Chek Instant Test Strips?
Test strips should be stored within the conditions specified by the manufacturer.
Do not intentionally store the strip vial in locations that may become excessively hot, such as:
- inside a closed vehicle exposed to sunlight,
- directly beside a heat source,
- on a sunny windowsill, or
- in another location outside the storage conditions printed on the pack.
If the strips have been exposed to extreme temperature conditions, Accu-Chek identifies this as a situation in which a control test may be appropriate.
Can Humidity or Moisture Affect Test Strip Storage?
The Instant strip vial should be kept securely closed when not in use.
Avoid unnecessary exposure of the remaining strips to moisture or high humidity. Handle individual strips with clean, dry hands.
Do not place a wet or contaminated strip back into the vial.
If the container has been left open in unsuitable humidity or the strips are suspected of being compromised, follow the manufacturer guidance and consider a control test before relying on the strips.
Can Accu-Chek Instant Strips Be Stored Outside Their Original Vial?
Keep unused test strips in the original Accu-Chek Instant test-strip vial.
Do not routinely transfer strips into:
- pill organisers,
- plastic pouches,
- unlabelled bottles,
- another test-strip vial, or
- loose storage compartments.
Using the original container also helps preserve the product identification, lot information and expiry reference associated with the strips.
Can You Touch Accu-Chek Instant Test Strips?
Accu-Chek states that Instant strips have a protective barrier along the strip to help protect the strip and its chemistry.
Nevertheless, good testing practice is to handle strips with clean and dry hands and avoid unnecessarily touching the blood-dosing area or contaminating the strip.
What If an Accu-Chek Instant Strip Looks Damaged?
Do not use a strip that appears:
- bent,
- damaged,
- wet,
- dirty,
- contaminated, or
- otherwise different from a normal unused strip.
Use a fresh strip from an in-date, correctly stored vial instead.
Accu-Chek also lists suspected strip damage as a reason to consider performing a control test.
What If the Strips Were Stored in Extreme Temperature or Humidity?
Accu-Chek specifically identifies exposure to extreme temperatures, humidity or both as a reason to check the meter and strips using a control test.
Do not assume that strips exposed to unsuitable conditions are automatically fine simply because they still look normal.
Follow the manufacturer instructions associated with the particular strip batch.
How to Check Accu-Chek Instant Strips Before Every Test
A quick pre-test check can become part of your routine:
- Confirm the strips are Accu-Chek Instant Test Strips.
- Check the printed use-by date.
- Confirm that the vial has been stored according to the manufacturer instructions.
- Make sure the container was properly closed.
- Remove one strip with clean, dry hands.
- Check that the strip is not visibly damaged or contaminated.
- Insert it into a compatible Instant or Instant S meter.
Can Active, Guide or Performa Strips Be Stored and Then Used in Instant?
Storage does not change test-strip compatibility.
Even if another Accu-Chek strip is correctly stored and within expiry, it cannot be substituted for an Instant strip if it belongs to a different meter system.
| Strip Family | Use with Instant? | Use with Instant S? |
|---|---|---|
| Accu-Chek Instant | Yes | Yes |
| Accu-Chek Active | No | No |
| Accu-Chek Guide | No | No |
| Accu-Chek Performa | No | No |

Accu-Chek Instant Test Strips 50 vs 100: Does Pack Size Change Expiry?
Microsidd's current Instant strip listing includes 50-strip and 100-strip options.
Pack quantity itself does not determine compatibility. Both are intended for the same Instant strip system.
However, expiry becomes an important purchasing consideration when buying a larger quantity.
| Pack Size | Consideration |
|---|---|
| 50 strips | Regular refill quantity |
| 100 strips | Larger supply; check whether expected usage fits the available expiry period |
Before purchasing a larger quantity, consider:
- the current batch expiry,
- your expected strip usage,
- your prescribed or advised testing schedule, and
- whether you are likely to use the strips before the printed expiry date.

Should You Buy More Strips Just Because the Price per Strip Is Lower?
Not necessarily.
When comparing 50 and 100-strip quantities, consider both price and practical usage.
A larger quantity can reduce the frequency of reordering, but buying more strips than you are likely to use before expiry may not provide practical value.
Check the current product listing for live pricing, available quantity and expiry information.
Does Opening the Vial Automatically Change the Printed Expiry Date?
Use the manufacturer instructions supplied with the specific Accu-Chek Instant test-strip batch as the authority for storage and expiry.
Do not invent a new use-by date or apply a rule from a different test-strip brand unless the Accu-Chek Instant packaging or product insert specifically instructs you to do so.
The clearly printed manufacturer use-by date and the storage instructions supplied with your strips should guide use of the product.
Can a Sealed Pack Be Used After the Expiry Date?
No. A pack being unopened does not override the manufacturer's use-by date.
If the printed expiry date has passed, do not use the strips even if the carton or vial has never been opened.
What Should You Do with Expired Test Strips?
Once the manufacturer's use-by date has passed:
- do not use the remaining strips for blood glucose testing,
- separate them from your in-date testing supplies, and
- begin using a fresh vial of compatible, in-date Instant strips.
Follow applicable local instructions for disposal of unused medical consumables.
What If a Result Does Not Match How You Feel?
Accu-Chek lists a result that does not match how the user feels as one of the situations where checking the meter and test strips with a control test may be useful.
Also review:
- whether the correct Instant strip was used,
- the printed expiry date,
- strip storage conditions,
- whether the vial was left open, and
- whether the testing procedure was followed correctly.
Do not use an online article to make treatment decisions from an unexpected glucose result. Follow your meter instructions and contact an appropriate healthcare professional when necessary.
