CGM? Still Perform the Fingerstick!

College student, type 1 diabetes, wears a pump and CGM. She has good family support. Several of her family members get her CGM readings on their phone. She received a call from her mother about 2:45 am waking her up. She told her to treat her low blood glucose, which patient reported to be 41.

Patient states her alarm had gone off, but she did not hear it. She performed a fingerstick because she didn’t feel like she was low. It was 149. (See report.) The CGM recalibrated. She did not treat because she did not need to.

She was always taught to check a fingerstick before treating. She was glad she was taught that. Had she not checked she may have had to deal with a high glucose level later.

Lessons Learned:

  • Technology helps, but it needs human input.
  • CGM’s accuracy may have proved to be accurate enough to treat from, but experience tells us each person responds differently, and accuracy can vary from person to person.
  • If symptoms don’t match readings, perform a fingerstick.
  • My recommendation is to continue to perform a fingerstick before treating, even though some say one does not have to.
