    Description of Event or Problem · 0

    MY FREESTYLE LIBRE 3 HAS ALERTED ME ON SEVERAL OCCASIONS THAT MY BLOOD SUGAR WAS CRITICALLY LOW (56 MG/DL). I HAVE GOTTEN UP AND REACTED BY IMMEDIATELY EATING/DRINKING ITEMS TO RAISE MY BLOOD SUGAR, WHICH RESULTS IN A SPIKE IN BLOOD SUGAR BECAUSE MY GLUCOSE WAS REALLY 102 MG/DL. I NOW HAVE TO DOUBLE CHECK IT WITH MY OLD METER VIA FINGER PRICK AND SEVERAL TIMES IT IS READING LOW. I HAVE BEEN A DIABETIC FOR OVER 20 YEARS AND HAVE MANAGED IT WELL. THIS SENSOR WAS SUPPOSED TO ELIMINATE FINGER PRICKING, BUT NOW I CAN'T TRUST THE DEVICE. I HAD A BATCH OF SENSORS DO THE SAME THING IN JUNE AND JULY. THIS IS A NEW BATCH: LOT T60003079; SN (B)(6) (2025-12-31 EXPIRATION). I DID NOT REPORT THE PREVIOUS TWO TIMES. I TAKE GREAT CARE TO PUT THE SENSOR ON AND I'VE FOLLOWED ABBOTT'S DIRECTIONS TO THE LETTER. PATIENT CODE: 1905. DEVICE CODE: 2460. REFERENCE REPORTS MW5174535 AND MW5174536.
