Can You Sell Expired Diabetic Test Strips?

No. Once test strips have passed their expiration date, reputable buyers will not accept them, and for a practical reason that has nothing to do with the buyer being overly cautious: an expired strip can no longer reliably measure blood glucose. The enzymatic compounds embedded in the strip degrade after the expiration date, as the FDA notes in its guidance on home glucose monitoring devices, making the readings unpredictable. A buyer who resells strips to people managing diabetes cannot sell something that may give them a false reading.

That’s the direct answer. But the more useful question for most people who land on this page is slightly different: how close to expiration can test strips be and still sell? Because “expired” and “about to expire” are not the same thing, and the gap between them is where most real-world situations actually live.

The Direct Answer: No, and Here’s Exactly Where the Line Is

Most buyers in this market set their cutoff based on how many months remain before expiration, not just whether the strips have technically expired yet. Here is how our policy works, published directly on our site so there’s no ambiguity:

• 10 or more months remaining before expiration: full price paid.
• 7 to 9 months remaining: 50% of the current price.
• 6 months or fewer remaining: not accepted.
• Already expired: not accepted.

The reason for these tiers isn’t arbitrary. It reflects the time it takes for strips to move through the resale process and reach someone who needs them. A box with nine months left when it ships to us may have seven or eight months left by the time it reaches a buyer. A box with two months left when it ships is effectively useless by the time it changes hands. The expiration date isn’t just a regulatory formality; it’s a hard downstream constraint.

This is why acting early matters so much. The difference between selling at full price, selling at half price, or not being able to sell at all often comes down to a matter of weeks.

Why Test Strips Have Expiration Dates in the First Place

Understanding why strips expire helps clarify why the cutoffs above are firm rather than negotiable. Each test strip contains a small amount of glucose oxidase, an enzyme that reacts with glucose in a blood sample to produce a measurable electrical signal. Over time, and especially when exposed to heat, humidity, or air, that enzyme breaks down. Once it degrades past a certain threshold, the chemical reaction no longer produces a reliable reading.

The expiration date printed on the box is the manufacturer’s certified guarantee that the enzyme is still functioning within their tested accuracy standards. After that date, the strips may still produce a number when used, but that number is no longer valid. For someone adjusting an insulin dose based on a glucose reading, an inaccurate result is not a minor inconvenience; it’s a meaningful medical risk. That’s why the FDA specifically advises against using expired test strips and why responsible buyers in this market don’t accept them.

What to Do If Your Strips Are Already Expired

If your strips have already crossed the expiration date, selling them to a buyback service is not an option. Here’s what you can do instead.

Dispose of Them Properly

Test strips that have come into contact with blood are considered medical waste and should be handled accordingly. Most unused, sealed, expired strips can go into regular household trash, but check your local municipality’s guidelines. Lancets and syringes require an approved sharps container. Many pharmacies offer sharps disposal programs for diabetic supplies. Our post on what to do with expired diabetic test strips covers disposal options in more detail.

Check Whether a Training or Education Program Can Use Them

Some caregiver training programs and diabetes education classes use expired strips for demonstration purposes, where actual glucose accuracy isn’t needed. This isn’t a universal option, but it’s worth asking a local clinic, hospital, or diabetes education center whether they have a use for expired materials.

Avoid Donating Them to Individuals Who Need to Manage Diabetes

Even with good intentions, passing along expired strips to someone who will use them for blood glucose monitoring is not a safe option. The risk of inaccuracy is real, and the person receiving them may not realize the strips are past their expiration date.

What to Do If Your Strips Are Near Expiration But Not Yet Expired

This is the situation where acting quickly makes a real financial difference. If you have strips with six months or more remaining, you still have a selling window. Seven to nine months get you half the value. Ten months or more get you full value.

The most common scenario we see: someone finds a box of strips they forgot about, checks the expiration date, and realizes they have a few months left. If there are at least seven months remaining, it’s worth submitting them now rather than waiting to see if the situation changes.

The process at More Cash For Test Strips is straightforward: check your strips against our price list, request a free prepaid shipping label or mailing kit, pack your supplies, and ship them. Payment goes out by check, PayPal, Cash App, Zelle, or wire once we’ve received and verified the order.

One important detail: strips must be factory-sealed with the box in good condition. An open box or damaged packaging is not accepted, regardless of the expiration date. If you’re not sure whether your strips qualify, our how it works page and FAQ cover the eligibility requirements clearly.

The Lesson: Don’t Wait

The single most actionable takeaway from this entire topic is that timing is everything when it comes to selling diabetic test strips. Strips that sit unused in a drawer don’t hold their value; they lose it, one month at a time, as the expiration date approaches.

If you’re managing a supply that’s building up, or if you’ve recently switched meters or had a prescription change, the right time to sell your diabetic test strips is while they still have ten months or more remaining. That’s when you get the full value, when the process is the most straightforward, and when the strips are most useful to the people they’ll eventually reach. Waiting costs money, and waiting too long costs the sale entirely.

We buy all major brands, including OneTouch, Freestyle Lite, Accu-Chek, Bayer Contour, and more. You can check your specific strips on our price list to see the current payout, then request your free shipping label to get started.

Frequently Asked Questions

Can you sell test strips that expired last month?

No. Once strips have passed their expiration date, they are not accepted by any reputable buyback service, including ours. The expiration date is the point at which the manufacturer can no longer certify the strips’ accuracy, and no responsible buyer will resell a product that may give inaccurate glucose readings.

What if my strips expire in two or three months?

Strips with fewer than six months remaining before expiration are not accepted. This threshold exists because by the time strips ship, are processed, and reach the next buyer, a short window becomes a closed one. If you have strips expiring in two to three months, the selling window has unfortunately passed.

Will buyers accept strips that expire in seven to nine months?

Yes, though typically at a reduced payout. At More Cash For Test Strips, strips with seven to nine months remaining are accepted at 50% of the current listed price. Strips with ten or more months remaining receive the full price.

Why won’t buyers accept expired test strips even if the box is sealed?

Because the buyer has to resell them to someone who will use them to manage their diabetes. An expired strip may still be physically intact and factory-sealed, but the enzyme inside can no longer be counted on to produce an accurate glucose reading. Selling expired strips downstream would put the end user at risk, which is why the line is drawn at the expiration date regardless of physical condition.

Can I tell if my test strips are expired by looking at them?

Not reliably. Expired strips often look identical to non-expired ones. The only reliable way to determine whether strips are usable is to check the expiration date printed on the box, typically on the side or bottom panel.

Is it illegal to sell expired test strips?

Selling diabetic test strips is legal when done through compliant channels with unexpired, sealed supplies. Selling expired strips is not a criminal act in the way that selling other regulated substances might be, but no legitimate buyer will purchase them, and selling expired medical supplies to someone who will rely on them for health decisions raises serious ethical and potential liability concerns regardless of legality.

What should I do if I have a mix of expired and unexpired strips?

Separate them before submitting. Include only the boxes that meet the minimum expiration threshold (six months or more remaining, with seven to nine months qualifying for 50% payout and ten-plus months qualifying for full price). Expired boxes should be disposed of separately. Sending expired strips mixed into an order with valid ones creates processing delays and will result in those boxes being excluded from your payout.
