Dexcom G7 Failures?
Ye are probably sick of me posting about this by now but I have some new information (thanks to ) and tips for getting replacements.
In the first picture you will see two sensors which have a hole right before where it says Dexcom. On the left is a functioning sensor where this hole is clear. On the right you will see part of the insertion which should stick into the skin, has curled around and is sticking out of the hole. This will cause a sensor failure.
You can report failures online (without having to wait in long phone queues) at this link: https://dexcom-intl.custhelp.com/app/support_request/ (sorry links don't work properly here but I will put in a story for today).
When requesting you will need your lot number and sensor number (SN). Your sensor number will usually start with (21) and can be found on either the box or the applicator (pictured below). When reporting there is a box to detail the problem, so make sure to let them know about the insertion curling up so that they know it's a common fault. Hopefully they will fix it.
Anyway, wishing you all functioning sensors and great days π Hope you enjoyed the little PSA.
