The Clinical Laboratory will change the normal range for fasting glucose to 70-99 mg/dl to meet the guidelines set by the expert committee on the diagnosis and classification of diabetes mellitus. According to the Follow-Up Report on the Diagnosis of Diabetes Mellitus, published in Diabetes Care 23:3160-3167, 2003, individuals with repeated fasting glucose values of greater than 99 mg/dl have an increased risk of developing diabetes. For glucose values obtained on non-fasting specimens, the fasting range does not apply.
