I’ve been using the Freestyle Libre as my only method of monitoring my blood sugar for quite some time. I was very encouraged by the readings, which consistently showed that I was within range about 92% of the time.
However, during my annual lab work, my A1C came back significantly higher than expected. That prompted me to double‑check my glucose levels using traditional finger‑stick blood tests and compare them to the Freestyle Libre sensor readings.
What I discovered was alarming: the sensor was off by an average of 80–90 points compared to actual blood test results. This level of inaccuracy is not only unacceptable — it’s dangerous. Consumers rely on these devices to make critical health decisions, and such discrepancies can lead to serious consequences.
Very irresponsible and potentially harmful to anyone depending on this product for accurate glucose monitoring.
