The GlycoMark® Test is More Accurate than HbA1c and Glucose for Predicting Mortality in Diabetic and Non-Diabetic COVID-19 Patients

Study Data Highlighted At 2021 American Heart Association Scientific Sessions

RALEIGH,N.C.,Nov. 16,2021 -- Precision Diabetes,Inc. today announces the presentation of data demonstrating that the 1,5-anhydroglucitol blood test (GlycoMark®) is more accurate than commonly used diabetes tests,hemoglobin A1c (HbA1c) and glucose,in predicting mortality in hospitalized COVID-19 patients with and without diabetes.The study,"1,5-anhydroglucitol is an Independent Predictor of Mortality in Patients with COVID-19," was presented at the American Heart Association (AHA) 2021 Scientific Sessions conference.

The study,conducted at Sinai Hospital in Baltimore,Maryland,showed that the GlycoMark® test had 76% mortality accuracy (AUC) compared to the accuracy for HbA1c and fasting glucose of 51% and 60%,respectively.Interestingly,the accuracy of GlycoMark® was higher in patients without diabetes (79%) than in patients with diabetes (73%). An algorithm,which included age,BMI,and GlycoMark® had an accuracy for prediction of mortality of 89%.

"We were pleased to find that the GlycoMark® test identified mortality with high accuracy in COVID-19 patients,said Paul Gurbel,MD,a cardiologist at the The LifeBridge Health Cardiovascular Institute and lead investigator of the trial.GlycoMark® may have utility in triaging COVID-19 patients in the hospital setting at higher risk of severity and mortality. This may be especially important in COVID-19 non-diabetic patients who may develop new-onset diabetes,which brings higher risks of severe disease and death."

This study follows a previously reported study presented as a late-breaking abstract at the 2021 American Diabetes Association (ADA) Scientific Sessions,which showed that GlycoMark® was an effective marker of stress hyperglycemia and severity in COVID-19 patients,particularly in patients without diabetes.The study was conducted at Hospital Universitario Cruces in Bilbao,Spain.
