Diabetic test strips are medical devices that millions of people living with diabetes depend on to monitor their blood glucose levels multiple times a day. This frequent monitoring is necessary for effective diabetes management, yet the cost of these supplies can be substantial, even with insurance coverage. This financial pressure has led to the emergence of a secondary, non-retail market where individuals purchase what are often referred to as “used” diabetic test strips. These strips are almost always unused, overstocked, or near-expired products sold outside of official distribution channels. This marketplace connects sellers who have an excess of supplies with buyers seeking a lower-cost alternative to pharmacy prices.
The Economic Drivers: Why Users Seek Lower-Cost Strips
The primary force driving the demand for secondary-market test strips is the high out-of-pocket cost of diabetes supplies in the regulated market. Even with health insurance, patients often face high deductibles and substantial copayments for their monthly supply of strips, which can cost upwards of a dollar per strip at retail price. For someone who needs to test frequently, the annual expense quickly becomes a significant financial burden. This financial strain is especially acute for people who are uninsured or underinsured, making the regular testing frequency recommended by physicians nearly impossible to afford. The secondary market offers a deep discount on these supplies, often selling them for a fraction of the retail price. For many, this gray market is the only viable method to maintain the testing frequency needed for safe and effective blood glucose control.
The Supply Chain: Why Individuals Sell Unused Strips
The surplus of unused test strips that fuels this market originates from diabetic patients who receive more supplies than they use. Insurance plans and prescription protocols sometimes result in an oversupply, where patients are sent a fixed, large quantity of strips regardless of their actual daily testing needs. Changes in a patient’s diabetes management, such as switching to a continuous glucose monitor (CGM) or changing to a different brand of meter, can also render a large stock of strips obsolete. Other circumstances, like the death of a patient, also contribute to the excess inventory that enters the resale market. The motivation for the individual seller is financial, allowing them to recoup some of the cost they or their insurance paid for the supplies. By selling their excess inventory, they turn what would otherwise become medical waste into a source of cash, creating a unique economic opportunity out of a healthcare system inefficiency.
Quality Control and Health Risks Associated with Resale
Purchasing test strips from unregulated sources presents a serious public health concern due to compromised quality control. Blood glucose test strips contain sensitive enzymes that react with the glucose in a blood sample to produce a reading. The accuracy of the result relies on the chemical integrity of these enzymes, which can degrade over time or when exposed to environmental factors.
Improper storage is a risk, as the strips may have been subjected to extreme heat, cold, or high humidity while in the possession of the seller or a reseller. Exposure to these conditions can compromise the chemical reagents, leading to inaccurate blood glucose measurements. When a reading is inaccurate, a patient may administer an incorrect dose of insulin. For example, taking too much insulin based on a falsely high reading can lead to dangerously low blood sugar (hypoglycemia). Conversely, taking too little based on a falsely low reading can result in dangerously high blood sugar (hyperglycemia). Both of these outcomes can lead to severe health complications, including coma or death.
Risks of Compromised Products
There is also a risk of receiving expired or tampered products, where expiration dates may have been altered to make the strips seem viable. The use of expired strips is discouraged because the enzyme viability is no longer guaranteed by the manufacturer, leading to questionable accuracy. Furthermore, there is a risk of cross-contamination if a pre-owned vial has been opened and contains trace amounts of blood from the original owner, which could pose an infection risk.
Regulatory Status and Ethical Concerns
Diabetic test strips are classified as medical devices and are regulated by the U.S. Food and Drug Administration (FDA) to ensure their quality, safety, and accuracy. The secondary market operates in a regulatory gray area. While the sale of unused, unexpired strips not obtained through government programs like Medicare or Medicaid is not strictly illegal in many places, the practice is strongly discouraged by the FDA and diabetes organizations. The FDA warns specifically against using pre-owned strips because their storage conditions cannot be verified, making their accuracy unreliable.
Ethical concerns surround both the buyer and the seller in this market. For the buyer, the desperation for affordability is exploited, forcing them to gamble with their health by using potentially compromised supplies. For the seller, the practice can create an incentive to ration their own supplies or to profit from a system designed to provide medical necessity. Manufacturers and authorized distributors strongly advise against these transactions, emphasizing that the lack of consumer protection and the potential for life-threatening inaccurate readings outweigh any perceived cost savings.
