DexCom is warning customers that some of its glucose monitoring sensors that had been marked for destruction were stolen and sold by third parties.

The maker of biosensors for people with diabetes said Tuesday that quality and accounting reviews uncovered the theft of two lots of Dexcom G7 sensors that had been designated for scrap.

Those sensors didn't meet DexCom standards and were sent to a third-party vendor for destruction and recycling. Instead, they were sold to and used by some customers, the company said.

"We are treating this matter with the utmost seriousness and are working closely with regulators and other authorities to ensure user safety, determine exactly how this product was stolen and hold the perpetrators fully accountable for their crimes," Chief Executive Jake Leach said.

The company said it has traced the unauthorized sales back to a business called Pharmsource, which is not an authorized DexCom distributor but does supply some independent pharmacies and Durable Medical Equipment distributors in the U.S. DexCom is warning pharmacies that buy from Pharmsource to review their inventory.

Sensors from one of the affected lots, if they're not sterilized properly, have an increased risk of skin infection. Sensors from the other lot have an elevated internal testing failure rate, and an increased risk of having no sensor readings available.
