Not so Smart Strips

The FDA issued a warning that certain glucose monitoring strips can get confused by non-glucose sugars. If a patient is undergoing peritoneal dialysis or has undergone surgery, certain therapies may call for products that contain non-glucose sugars like maltose, galactose and xylose. These sugars can give a falsely high blood sugar reading when GDH-PQQ test strips are used and cause patients and caretakers to over treat with too much insulin.

GDH-PQQ stands for glucose dehydrogenase pyrroloquinoline quinone, and the FDA has published a list of strips that may cause a false high reading. Widely used GDH-PQQ test strips such as the Accucheck, TRUEtest and Freestyle brands fall into this listing.

This alert shouldn't affect your day to day use of these strips and monitor systems, but please be sure to look into this if your child has recently undergone surgery.
