Does my Duo or Nano need to be calibrated?

Nope - calibration is not necessary for your Center Health meter!

All of our meters come factory calibrated and have been tested for accuracy. If you'd like to read more about how accurate Center Health products are, you can visit this page: https://help.center.health/article/5-is-the-nano-accurate

Additionally, we do provide control solution upon request to verify that everything is working accurately - if you'd like a bottle, please reach out to us from the app or via email at yourfriends@center.health 🙂 One of our Patient Support Associates would be happy to discuss any accuracy concerns you may have, and send you a bottle of control solution free of charge!
