[Posted 08/13/2009] FDA notified healthcare professionals of the possibility of falsely elevated blood glucose results when using GDH-PQQ glucose test strips on patients who are receiving therapeutic products containing certain non-glucose sugars. These sugars can falsely elevate glucose results, which may mask significant hypoglycemia or prompt excessive insulin administration, leading to serious injury or death.
GDH-PQQ glucose monitoring measures a patient’s blood glucose value using methodology that cannot distinguish between glucose and other sugars. Certain non-glucose sugars, including maltose, xylose, and galactose, are found in certain drug and biologic formulations, or can result from the metabolism of a drug or therapeutic product. The FDA Public Health Notification provides a list of GDH-PQQ Glucose Test Strips and recommends that healthcare practitioners avoid using GDH-PQQ glucose test strips in healthcare facilities or take steps to never use them on patients receiving interfering substances.
FDA encourages the voluntary reporting of any medical device adverse events related to glucose meters or glucose test strips that do not meet the requirements for mandatory reporting. Adverse events should be reported to the FDA's MedWatch Adverse Event Reporting program online, by phone [1-800-332-1088], or by returning the postage-paid FDA Form 3500 by mail [to MedWatch, 5600 Fishers Lane, Rockville, MD 20852-9787] or fax [1-800-FDA-0178].
