Study suggests that diabetes can be accurately diagnosed from a single blood sample

(American College of Physicians) A combination of elevated fasting glucose and HbA1c levels from a single blood sample was found to be accurate for diagnosing diabetes. This is significant because current guidelines state that a second blood test, conducted a separate point in time, is requited to confirm a diagnosis of diabetes. Findings from a prospective cohort study are published in Annals of Internal Medicine.
