Compared to the above urine test, a blood test for glucose is more accurate in avoiding both false positive and false negative results in identifying diabetic patients. If a blood test for glucose correctly identifies 90% of diabetic patients, but gives false-positive results for 12% of non-diabetic patients, then: the blood glucose test has improved sensitivity, but reduced specificity (compared to the urine test) the blood glucose test has improved neither sensitivity nor specificity (compared to the urine test) the blood glucose test has reduced both sensitivity and specificity (compared to the urine test) the blood glucose test has improved both sensitivity and specificity (compared to the urine test) the blood glucose test has improved specificity, but reduced sensitivity (compared to the urine test)

You are an endocrinologist in a Diabetes Centre, and a 38 year-old person who has no signs (symptoms) for diabetes arrived to your clinic, but when you checked his fasting blood sugar (FBS) level, it was 132 mg/dL (7.3 mmol/L).
