Test results will be issued at the time of the screening. Dr. J. David Maher, a family physician at Decorah Clinic, suggests that patients do not eat solid foods and drink only water after midnight on the evening before the screening. Following these instructions will provide the most effective screening. Glucose screening is important for early identification of diabetes, says Dr. Maher. Patients with mild diabetes might not exhibit symptoms for years.
Many adults are unaware that they are diabetic until they have a glucose test.
As with most medical conditions, the earlier we identify diabetes, the great our chance of controlling it and helping patients lead more comfortable and fulfilling lives, he says.
