Unused Test Strips After Switching to a CGM
Switching from fingerstick testing to a continuous glucose monitor (CGM) is one of the most common reasons people end up with a surplus of unused test strips. If you’ve made the switch and have unopened boxes left over, here’s what to do with them.
Why This Happens So Often
Many people stock up on test strips before a CGM prescription is approved, or simply have a backlog built up over months of routine refills. Once a CGM takes over daily monitoring, fingerstick testing often drops to occasional calibration checks or backup use — leaving far more strips than you’ll realistically use.
You Still Need Some Test Strips as Backup
Before selling or donating all of your strips, keep in mind that most CGM systems still recommend keeping some backup test strips on hand for calibration (depending on the model) or in case your sensor fails. Don’t clear out your entire supply — just the excess.
Option 1: Sell Your Unopened Surplus
Unopened, unexpired test strip boxes retain real resale value. MyDiabetesGuru purchases unused test strips directly from individuals, which is often the simplest way to recover value from strips you no longer need in bulk.
Option 2: Donate Unopened Boxes
Local health clinics, diabetes nonprofit organizations, or community health centers sometimes accept unopened test strip donations for patients without reliable access to supplies.
Option 3: Check With Your CGM Provider
Some CGM manufacturers or suppliers have guidance or programs related to leftover testing supplies during a transition — it’s worth asking during your onboarding process.
What About the Meter Itself?
If you also have an unused glucose meter from before your CGM switch, many buyers accept meters along with test strips. Don’t forget to include it when requesting a quote.

FAQs About Unused Test Strips After a CGM Switch
Do I still need test strips if I have a CGM? Most CGM systems recommend keeping some backup test strips on hand, even if you no longer test as frequently — check your specific device’s guidance.
Can I sell test strips that are a few months away from expiring? Many buyers accept test strips with a reasonable amount of shelf life remaining — the more time left, the stronger the offer is likely to be.
What if I have strips for a meter brand I no longer use? As long as the boxes are unopened and unexpired, most buyers will still purchase them regardless of whether you currently use that meter.
Should I sell my old meter too? Yes, if it’s in good working condition, many buyers accept unused meters alongside test strips.
Is it safe to give away my old testing supplies to a family member? If the supplies are unopened and unexpired, this is generally fine, though it’s worth confirming they use a compatible meter brand.
Conclusion
A CGM switch is one of the most common reasons for a surplus of unused test strips, but it’s also one of the easiest situations to resolve — just keep a small backup supply and sell or donate the rest before it expires.
