In GDH-based glucometers, glucose oxidation can be catalysed by different cofactors: nicotinamide adenine dinucleotide (GDH-NAD), flavin adenine dinucleotide (GDH-FAD), pyrroloquinolinequinone (GDH-PQQ) and mutant GDH-PQQ. GOD-based and GDH-NAD-based glucometers are substrate-specific and do not react with sugars other than glucose. GDH-FAD reacts with xylose only in addition to glucose. GDH-PQQ is not glucose-specific; in addition to glucose, it reacts with different other sugars and produces falsely high values of capillary glucose in the presence of such substances. There are reports of several deaths associated with usage of GDH-PQQ-based test strips. A modified form of GDH-PQQ, the so-called mutant GDH-PQQ, is supposedly free from such interferences. In this article spuriously high glucose values due to maltose interference in a glucometer using the mutant GDH-PQQ chemistry are being reported.<\/jats:p>","DOI":"10.1136\/bcr-2017-219928","type":"journal-article","created":{"date-parts":[[2017,5,12]],"date-time":"2017-05-12T05:24:03Z","timestamp":1494566643000},"page":"bcr-2017-219928","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":10,"title":["Erroneously elevated glucose values due to maltose interference in mutant glucose dehydrogenase pyrroloquinolinequinone (mutant GDH-PQQ) based glucometer"],"prefix":"10.1136","volume":"2017","author":[{"given":"Partha Pratim","family":"Chakraborty","sequence":"first","affiliation":[{"name":"Department of Medicine, Midnapore Medical College and Hospital, Midnapore, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinjan","family":"Patra","sequence":"additional","affiliation":[{"name":"Department of Medicine, Midnapore Medical College and Hospital, Midnapore, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rana","family":"Bhattacharjee","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, IPGMER\/SSKM Hospital, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Subhankar","family":"Chowdhury","sequence":"additional","affiliation":[{"name":"Department of Endocrinology and Metabolism, IPGMER\/SSKM Hospital, Kolkata, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2017,5,12]]},"reference":[{"key":"2025082704070918000_2017.may11_1.bcr-2017-219928.1","doi-asserted-by":"publisher","DOI":"10.2337\/dc09-1822"},{"key":"2025082704070918000_2017.may11_1.bcr-2017-219928.2","unstructured":"U.S. Food and Drug Administration.
