Welcome to TuD, @Georgia_Barnwell. That’s frustrating. You mentioned that you treated a false low with glucose and then finger-checked and discovered you were actually high. My first question to you is: did you thoroughly wash and dry your hands before that fingerstick?
I’ve been bitten by that circumstance more than once. I’ve concluded that any high fingerstick reading that meant adding insulin to correct, I will always wash and dry my hands and re-check before adding correction insulin.
Our meters are generally accurate and dependable but they’re not perfect.
One thing I do every 90 days when I see my doctor and get an A1c check, is to get a lab plasma glucose check done and I do three fingerstick readings right after the lab draw. I average those three readings and compare to the lab number. That check, if the the lab and meter are reasonably close, confirms that meter/strips I’m using are accurate enough.
I don’t use a LIbre flash glucose monitor but I have read some accuracy complaints by online users. People overall seem generally happy with the system. It’s definitely less expensive than the Dexcom, the system I use.
Is it possible for you to switch to a Dexcom? I know there are people who use the less-expensive Libre since they have to pay out of pocket for this technology.
Have you called Abbott to see if it’s possible that you have some sensors from a bad lot?
Sorry for the frustration. When I travel, I try to bring with me 2-3x the supplies I expect to use to cover unexpected events. Diabetes seems to feature unexpected events. I hope you were able to get your strips without missing too much of the conference. Your immediate safety and health come first.
Please report back, especially if you can positively resolve your Libre/fingerstick disagreements. I highly recommend that you regularly check your meter against a lab. It’ll help you remain confident that your meter is giving you accurate readings. And failing to wash hands before fingersticking is a common source of inaccurate readings that often lead to incorrect treaments. Good luck!
